Endress+Hauser’s iTHERM TrustSens hygienic resistance temperature detector (RTD) is a self-calibrating temperature sensor that can be used in bio/pharma processes to eliminate the risk of undetected ...

You can achieve accurate resistance-temperature-detector sensor measurements without having to resort to using a precision current source.

Both the RTD itself and its accuracy must be considered when selecting the RTD sensor. The temperature range varies with element type, and theaccuracy denoted at calibration temperature (usually at ...

This software-controlled RTD emulator produces voltages that cover the output range of the sensor. It supports all three RTD wiring configurations and associated sense-wire configurations.

To calibrate this circuit, replace the sensor with a precision decade box. Set the decade box to simulate 0°C and adjust the offset trim of R 2 for an output of 0V at Pin 7 of IC 3 .
