Video highlights use of foil resistors in strain gauge calibration

Vishay Precision Group has announced that its Vishay Foil Resistors brand (VFR) has released a new video that demonstrates the shunt calibration of strain gauges using Bulk Metal Foil resistors.

According to the company, foil resistors provide long-term accuracy and stability regardless of the operating environment, and are an alternative to using certified weight standards for calibration. 

To illustrate how strain gauge measurement systems can be calibrated electronically using VFR Bulk Metal Foil precision resistor shunts, the video employs a demonstration setup utilizing a half bridge connected to a Micro-Measurements 350 ? / 350 ? strain gage beam. To detect any change in resistance when under load, the bridge is deflected by a precisely known amount using a VFR precision resistor in parallel with one side of the strain gage. The amount to be deflected corresponds to the deflection caused by a specific weight standard and is calculated using the well-known parallel resistance formula: ‘product over the difference.’
