The TrustSens RTD from Endress+Hauser is a self-calibrating temperature sensor that 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 cycle, eliminating the risk of an undetected calibration drift and the risk of bad batches. It has a built-in, high-precision ceramic reference based on the Curie Point of the reference material and can be detected electronically. TrustSens has built-in Heartbeat Technology to monitor the sensor and send warnings when it detects a sensor failure, drift, or other measurement errors. The unit measures temperatures from 40 degrees below zero to 320 degrees F, works in pressures up to 725 psi, and provides a 4-20mA output with HART. 888-363-7377; www.us.endress.com/TrustSens
