The iTherm TrustSens hygienic RTD temperature sensor’s self-calibration process functions in situ and provides the necessary documentation to meet the conformance requirements for various regulatory agencies. The sensor is calibrated after every sterilize-in-place (SIP) cycle, eliminating the risk of an undetected calibration drift and of bad batches. It has a built-in, high-precision ceramic reference based on the Curie Point of the reference material (the temperature at which its ferromagnetic properties abruptly change). The sensor measures temperatures from -40 to 160 °C, works in pressures up to 725 psi and provides a 4-20 mA output with HART.
