Endress+Hauser’s iTHERM TrustSens, deemed the world’s first self-calibrating thermometer, has been recognized by Hannover Messe with the prestigious Hermes technology award. The compact thermometer is designed especially for hygienic and aseptic applications in the food and beverage and life sciences industries. With automated and fully traceable self-calibration during production, the sensor eliminates the risk of undetected non-conformities, resulting in maximum product safety and process efficiency. The integrated Heartbeat Technology additionally allows for continuous device diagnostics and verification without interruption of the process.
Developers used physics phenomenon
iTHERM TrustSens relies on an integrated reference sensor. The developers used the so-called Curie point physics principle, in which the magnetic properties of a material abruptly change at a specific temperature point. This point is determined for the reference sensor. As soon as the temperature falls below this value, such as following a steam sterilization, both sensors are adjusted. Since the Curie point remains constant, the reference sensor as a master provides a stable comparison value.
The probe thus calibrates itself each time the system is cleaned or sterilized as is usual in processes in the food & beverage and life science industries.
Large systems often include hundreds of temperature sensors that must be calibrated several times a year. To date, this has required stopping the process and removing the instruments. iTHERM TrustSens omits that. For more information, watch a video demo of iTHERM TrustSens technology.
