A range of slimline (21mm diameter) submersible plastic level sensors for continuous level measurement in confined spaces and small-size boreholes is now available from instrumentation specialist Impress Sensors & Systems Ltd. 

With a diameter of 21mm, the LMK 806 series of PVC-housed submersible ceramic level sensors is specially designed for hydrostatic level measurement of wastewater and other aggressive media, particularly where the sensor needs to be mounted inside a confined space such as an existing small size borehole, ¾” pipe or tube. Typical applications include wastewater treatment plants, chemical dosing stations, sewage lift stations, water recycling plants, storage tanks and landfill sites.

LMK 806 level sensors benefit from a PVC housing that provides maximum media compatibility and protection from virtually any aggressive media, including most acids and strong alkalis. Different cable materials (e.g. PVC, PUR, FEP) and seals are available to suit a range of different media.

The sensing technology on the LMK 806 series is a flush-mounted ceramic sensing element, which provides high reliability in long-term installations. Reliability is further enhanced by a nose cone, which when removed, exposes the flush diaphragm. This allows the sensor to be easily cleaned and any solid media removed, thus preventing clogging.

Sam Drury, Sales & Marketing Director at Impress Sensors & Systems comments: “It’s unusual to find a plastic level sensor with such a small diameter [21mm]. Most plastic level sensors are much bulkier. The LMK 806 level sensor should therefore appeal to a wide range of customers who require a submersible plastic level sensor for use in confined spaces in pipes, tubes and small size boreholes.”

Nominal pressure ranges are from 0…6mWG up to 0…200mWG. Accuracy is +/-0.5% FSO to IEC 60770 and so includes all setting errors, making this a high accuracy level-measuring instrument. The sensor provides excellent linearity, long-term stability and a high level of electrical protection (emission and immunity according to EN 61326) to prevent damage once the unit is installed in the field. Output signal is 2-wire, 4…20mA.

Fire: a basic requirement for the survival of our species.   To make fire, all you need is a source of fuel, an ignition source and some oxygen.   And there you have it, a very inefficient fire, producing a great deal of smoke and wasting most of the available of heat.   This may be very pleasant around the camp-fire but it’s far from ideal in the home!

We now live in a world where resources are dwindling.   Put simply, there are fewer things left for us to burn.   We are also, quite rightly, concerned about what we are putting back into the atmosphere so we have to be careful how we burn the fuel we have left.

Bioenergy is certainly one of the answers but, just because it is a “renewable” energy source, that does not mean we can afford to be wasteful with it.   For example, in order to maximise return on investment in the installation of a new industrial boiler, running costs need to be kept to a minimum.

Clearly, the design of the boiler will have a considerable effect not only on combustion efficiency but will also help minimise emissions.   However, the best way to achieve both of these goals: squeeze the greatest amount of energy from any fuel, while keeping harmful emissions to an absolute minimum, is by monitoring the flue gases and controlling the combustion process accordingly.

According to Carbon Trust, the air to fuel ratio within the boiler flue is one of the main factors affecting boiler efficiency. The technology of air to fuel ratio is set during commissioning and over time this tends to drift due to the changes in the fuels calorific value, combustion air temperature and control electronics. As a result of this, the boiler uses more energy to burn more fuel, causing increased emissions and increased costs. Studies illustrate that if you have a large, continuously operating boiler plant, you are likely to save at least 5% and recoup your costs within 2 years.

Many boiler manufacturers have discovered the benefit of using oxygen sensors also known as oxygen trim systems to optimise the process of burning fuel.    That is not only good for the environment but also for the end-user’s pocket.

The oxygen sensor system is inserted directly into the boiler flue which is connected to a control panel that continuously monitors the oxygen concentration enabling complete control over the boilers air to fuel ratio. Meaning that factors influencing drift within the boilers environment such as barometric pressure and high temperature do not force the boiler to run less efficiently that it is capable of. 

Zirconium Dioxide (ZrO₂) sensors are the most common type of sensor used in the field and the sensors from SST Sensing Ltd have been used reliably in boiler exhaust gases for over 25 years.   This is a dynamic oxygen cell product and it is rapidly gaining popularity in the field.   The fully porous, stainless steel cap allows a free flow of the flue gases to reach the sensor, while trapping any soot or debris which might lead to sensor malfunction.   Unlike other types of sensors, which can quickly become inaccurate as this build-up occurs, SST’s sensors will last for years even in badly regulated combustion processes before the dirt and pollution has any effect.

Why Use SST’s Zirconia Oxygen Systems?

Used in a variety of applications, SST’s Zirconium Dioxide Oxygen Sensor and Analysers are the product of choice where:

• Reliability and accuracy are required,
• Robustness in harsh environments is essential,
• Calibration, if necessary, is easily performed,
• Resistance to carbon deposits and other pollutants is vital,
• Increasing efficiency and minimising emissions is fundamental,

SST Sensing’s range of sensors and analysers meets all of the above requirements with ease.   They are accurate to within a fraction of a percent of reading, robust and reliable enough that they have been used for many years on aircraft and are extremely easy to calibrate when necessary.   Our high quality analysers, combined with our excellent customer service and strong commitment to protecting the environment, are the foundations for SST Sensing’s growing success.

The oxygen sensor system can be supplied with the control electronics separately or as an integrated analyser solution, both of which use the same technology.

To be cost effective, oxygen control systems are really designed for large boilers of over 500kW of output. They can work with natural gas, LPG, oil-fired and dual fuel burners.

A cost-effective approach to field calibration of thermocouples and PRT sensors permits fast and economical probe evaluation with National Standards traceability.

The Labfacility “mini-lab system” includes everything required for “local” highly precise calibration of  Thermocouple and Pt100 probes. Considerable savings in time and expense can be achieved by using such a system instead of sending platinum resistance thermometers to the appropriate laboratories for routine or special calibrations in every case. A considerable advantage is realized when site problems associated with temperature reading errors are suspected; the “system” can be set up anywhere to permit fast and convenient probe checking.

The “System” is supplied with the appropriate Traceable certifications and thus qualifies as a traceable calibration standard. This approach is not an alternative to the calibration laboratory but will complement the established National Laboratory calibration procedures. The kit uses a metal block thermal reference to provide very stable isothermal temperatures between –50^oC and 1100^oC which are measured with a calibrated sensor and a Labfacility Labcal PRO digital indicator.

Any temperature measurement installation comprises the sensor (with or without a signal convertor/transmitter), interconnecting wires and an associated instrument display/computer). In order to verify the overall accuracy of measurement, a heat source (thermal reference) must be used to generate an accurately known stable temperature which is measured independently of the installation.

The probe from the site installation is inserted in the thermal block and its reading is compared with the known (calibrated) temperature. The Labcal PRO is a laboratory standard digital temperature meter with many important and useful features. It is designed to provide fast, precise temperature measurement on an absolute or comparative basis.

For example, a display of either the reference sensor or the installed sensor value can be selected in sequence or as a differential temperature. Since the indicator remembers the corrected readings of the reference sensor, the display directly indicates its actual temperature. The difference reading shown, say +0.5^oC is thus the total actual error in the installation; the user does not have to refer to tables or carry out calculations.

Readings can be displayed in ^oC, ^oF, Kelvin, millivolts or Ohms as desired, which makes the system attractive to both industrial and laboratory users. The microprocessor based instrument is digitally configured for  thermocouple  ( types J, K, T, E, N, R, S & B) and Pt100 sensors; calibrated sensors can have their “Cal-point” values set into a memory in which case the instrument can display direct, corrected temperatures with probe tolerances eliminated from readings. Display resolution is 0.01^oC.

A calibration certificate is available for the reference sensor and indicator combination which can be periodically recertified at an appropriate laboratory. The complete system is easily transported and can be carried by one person. It can be used in electrically “noisy” environments and is ruggedly constructed. A fast warm-up feature  of the dry block calibrator allows readings to be made within 15 to 30 minutes from “switch-on”. A wide range of reference temperatures between -50^oC and +1100^oC can be provided. Designed for ease of use, readings are provided directly in ^oC or ^oF as required without the need for calculation from tables.

Reliable backup is absolutely vital in the nuclear industry including the Culham Centre for Fusion Energy (CCFE), the UK’s national laboratory for fusion research, based at Culham Science Centre in Oxfordshire. Owned and operated by the United Kingdom Atomic Energy Authority  CCFE hosts the world’s largest magnetic fusion experiment, JET (Joint European Torus), on behalf of its European partners.

For more than 30 years JET has used an in-line ultrasonic flowmeter to monitor the flow of the water cooling system for the site. For energy saving reasons the water cooling system operates in two modes, ‘Silent Hours’ and ‘Normal Hours’. During ‘Silent Hours’ the flow demand is reduced to 700m3/h which means that only one of the four main 160kW pumps is running. The ‘Normal Hours’ mode is selected at the start of daily operations when the process opens up various valves on the distribution system. This is achieved with a PLC control system, which monitors flow demand from the in-line ultrasonic flow meter to sequentially control the three other pumps over a 20 minute period until all four pumps are running providing a total flow of approximately 3500m3/h.

Performance of the in-line flow meter was becoming unreliable and a decision was taken to install a backup system. CCFE already used a Micronics Portaflow 300 for portable monitoring and were confident that a Micronics Service Engineer could recommend a suitable fixed clamp-on meter to provide a permanent solution. The Ultraflo 3000 was chosen because it offered a non-invasive, quick and reliable flow measurement solution.  With its easy to follow menu and simple set up it proved to be a cost-effective alternative to a traditional in-line meter installation. No installation drain down or pipe cutting was required and in addition dry servicing is possible so that downtime is kept to a minimum, absolutely vital in an industry which is so fast-moving.

David Gear, CCFE Technician, has total confidence in the Micronics product. “It is crucial to have the ability to monitor the cooling process and the flow in the site cooling water circuits supplying cooling to various systems associated with the JET fusion experiment”

The UK has had a thriving industry in the nuclear sector since the 1950’s. Nowadays, the industry spans the full nuclear life cycle from the design of new plant through to decommissioning and waste management. And this example demonstrates that there is significant potential for replication throughout the nuclear industry.

Barry Atkins, managing director of independent test equipment experts PASS, cautions that there is no need to risk fines for breaching noise at work regulations when the cost of compliance is so low.

In Early October, a Keighley furnishings company was fined after failing to protect its workforce from excessive noise levels on production machinery. Bradford Crown Court was told that an investigation by HSE found the company had not made a suitable assessment of the noise levels in the factory between 2006 and 2013.

The employer should have known its workforce was being subjected to loud noise and made personal hearing protection compulsory when the production changes were made. However, hearing protection was not introduced until 2013.

In addition a health surveillance programme for noise exposure should have been operating for affected workers, but this was not brought in until 2013, when 40 employees had to be given a hearing test. The company was fined £15,000 and ordered to pay £4,457 in costs after admitting breaching Section 2(1) of the Health and Safety at Work Act 1974.

The Control of Noise at Work Regulations 2005 came into force for Great Britain on 6th April 2006. The level at which employers must provide hearing protection and hearing protection zones is now 85 decibels (85dB) daily or weekly average exposure, and the level at which employers must assess the risk to workers’ health and provide them with information and training is now 80dB.

Logarithmic measure in decibels

Sound level meters measure sound pressure levels in industrial, environmental and aircraft applications as a logarithmic measure in decibels above a standard reference level. Their main components are a microphone, a signal processor and a display device.

According to IEC 61672-1 Electroacoustics Specifications, there are three types or classes of sound level meters: conventional meters that measure exponential time-weighted sound, integrating or averaging meters that measures time-average sound levels, and integrating meters that measures sound exposure level. Sound level meter prices start from under £40 for a basic Type 2 meter to over £4,500 for a sophisticated Type 1 meter.

The Amprobe SM-10 Type 2 sound meter measures sound from 30-130dB at a frequency range from 31.5Hz to 8KHz. It provides fast and slow response settings for checking peak and average noise levels. It allows health and safety engineers to perform acoustic analysis to assure compliance with safety codes and regulations.

The user can select the desired response time and weighting. If the sound source consists of short bursts or if only capturing peak sound, the response is set to fast. To measure average sound level, the slow setting is used and an ‘A’ weighting is selected for general noise sound level while a ‘C’ weighting is selected for measuring the sound level of acoustic material.

The Extech 407732 Type 2 meter has two separate measurement ranges for lower and higher sound volume applications. In the low range it can measure 35-100dB but in a noisier environment, the higher measurement range is 65-135dB, making it equally suitable for use in quiet offices or noisy factories.

As well as selecting ‘A’ or ‘C’ frequency weighting and fast or slow response, pressing the ‘max hold’ mode button only updates the meter display when a higher reading is detected than the one already on the display. A ‘data hold’ function works in similar fashion.

An external calibrator that can provide a 94dB signal at 1 kHz is required to calibrate the Extech 407732, but calibrate.co.uk can provide a full sound meter calibration service for meters from several different manufacturers.

Protective wind vane

The Testo 815 sound level meter measures sound level with an accuracy of plus/minus 1dB and resolution of 0.1dB, and features a protective wind vane for use outdoors. It uses frequency weighting to characteristic A and C, maximum and minimum value memory and built-in tripod knuckle screw. The fast/slow button may be used to change response time from 1s to 125ms.

The Chauvin Arnoux CA834 Type 2 recording sound level meter offers four measurement ranges up to 130dB, data capture software and internal memory capacity for 32,000 readings. Measurement ranges include 30-80dB, 50-100dB, 80-130dB and 30dB-130dB auto ranging. Captured data can be transferred to a PC by using an RS-232 cable.

As stated previously, a sound calibrator usually provides a reference sound pressure level of 94 dB and/or 114 dB at a frequency of 1 kHz. The sound calibrator must have a traceable and documented calibration certificate from a higher level laboratory, usually from a national metrology institute.

Regular calibration of sound level measurement equipment ensures that all testing results are accurate, and professional calibration laboratory technicians are able to match a sound meter against a known standard in order to ensure that the device is working within acceptable sound level parameters.

Temperature control is critical for many industrial processes, and although in many instances a simple controller can be sufficient, a growing number of applications require high precision temperature control. Ian Collins, Product Manager at West Control Solutions, outlines the role of cascade control in temperature control and how it can be used to improve process quality.

What is cascade control?

Directly heating a product can cause damage in manufacturing processes, so a secondary medium, usually liquid or gas, is often used to transfer heat to the product. The downside is that this often introduces a high level of themal lag to the system, leading to overshoot and instable control. It is difficult for a single instrument to control the temperature precisely when these conditions exist.

Cascade control is a temperature control method that links two control loops in sequence to eliminate this problem. The first controller is known as the master and its role is to monitor the temperature of the end product. The output of the master controller is then used to drive the setpoint of the second control loop, known as the slave. The role of the slave is to control the main heater load and the setpoint driven by demand from the master. As a result, the control system monitors changes at both the end product and at the heater, controlling the system accordingly. This method of control is particularly effective in applications where process variables have a high risk of disturbance and may not remain constant

Cascade control in application

Cascade control can be utilised in many applications across industry. For example, in dairy pasteurisation where water is used to heat milk. In this application water reaches temperature quickly while the milk heats more slowly, which can often lead to overheating. It’s crucial that the milk in this process must not overheat for reasons of reduced product quality. With single loop control the water temperature during the heating process would continue to rise until the milk reached its setpoint – a satisfactory outcome at this stage. Although single loop control generally achieves setpoint efficiently and at speed, problems occur in the moments that follow because the lag created by the process of heating the water to in turn heat the milk results in temperature overshoot of the milk, which seriously compromises the product quality. The answer is to utilise cascade control using two loops, with one loops measuring the temperature of milk and a second loop measuring the water temperature.  In this example the cascade control system relies on the measurement recorded by the rising temperature of the milk to slowly decrease the heat of the water, allowing the milk to continue heating at a pace that will not result in overshoot. 

Although cascade control is popular in the food and beverage industry, cascade temperature control can be used in many more applications than only food and drink manufacture. Such as in heat exchnagers for industrial building heaters, which can benefit from using cascade control to overcome temperature overshoot. A typical example in this application would see a product setpoint temperature programmed on a master controller that is then compared to the product temperature, in which case a maximum input value restricts the jacket temperature. At start-up the master loop compares the product temperature to its setpoint and gives maximum output. This sets the maximum setpoint on the slave, which is compared to the jacket temperature that is giving maximum heater output.  As the jacket temperature rises, the slave’s heater output falls and the product temperature also rises at a rate dependant on the transfer lag between the jacket and product. This causes the master’s output to decrease, reducing the ‘jacket’ setpoint on the slave, effectively reducing the output to the heater. This continues until the system becomes balanced.

Setting up and tuning

As the aforementioned application examples outline, there are a wide range of possible uses for this temperature control method. Once cascade control has been correctly specified for an application, it is then essential that it is correctly configured to meet the requirement of that specific application. To ensure correct configuration the first step is to ensure the secondary loop is tuned before the primary loop, because if the primary loop is tuned first then the secondary loop setpoint will constantly change and the autotune function will be constantly recalculating and unable to tune.  Therefore, a fixed setpoint should be entered on the secondary loop so that other parameters can be tuned. Once complete, the primary loop can be tuned and the secondary loop setpoint can then become dependent upon the primary loop. 

Cost-effective control

In applications where multiple substances cannot be adequately controlled by a single controller, the installation of highly effective cascade temperature control equipment enables the reduction of temperature overshoot and fluctuation in control. By consulting with a temperature control specialist, manufacturers across from industry can successfully preserve product quality in a cost-effective manner and optimise application efficiency.
