Fast-responding dew-point transmitter designed for tough industrial conditions
Michell Instruments has announced the launch of its new SF82 dew-point transmitter for compressed air quality.
The fast-responding moisture sensor has been designed specifically for use on compressed air dryers installed in compressor rooms. In these areas, temperatures can easily reach +50 °C while measurements of dew points below -60 °C are required. It comes calibrated to one of four standard measurement ranges to cover the requirements of industrial dryers in various applications. Non-standard ranges are also available on request to ensure complete flexibility.
The moisture transmitter uses the PST Group thick-film measurement technology coupled with microcontroller electronics to provide accurate and stable measurement across the transmitter’s product life. As well as ultra-fast response to moisture changes the dew-point sensor has an accuracy of ±2 °C dew point.
The SF82 is suitable for use in all types of industrial dryers: refrigeration dryers, membrane dryers and absorption dryers. Because compressed air is a ubiquitous utility, the moisture sensor has applications in a wide range of markets including medical and surgical air, breathing air, plastic injection moulding as well as compressed air used for instrumentation. The new unit has dual analog and digital outputs for use in electronic monitoring and control systems – including cloud-based Industry 4.0 systems such as the Rotronic Monitoring System (RMS). With both mini-DIN and M12 pin connectors as well as a wide range of process connections, it is compatible with all global standards for easy installation and integration with existing equipment.
Michell Instruments is a member of the Process Sensing Technologies (PST) Group. This is a group of manufacturers who together provide an unmatched suite of instruments, analysers and sensors for precision measurements in industrial process control and environmental monitoring.
