Endress+Hauser is recognized by Hannover Messe with the prestigious Hermes technology award for iTHERM TrustSens, which the company claims is the world’s first self-calibrating temperature probe for industrial applications. The compact thermometer iTHERM TrustSens 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, according to Endress+Hauser. The integrated Heartbeat Technology additionally allows for continuous device diagnostics and verification without interruption of the process.
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 and beverage and life science industries. Large systems often include hundreds of temperature sensors that have to be calibrated several times a year. To date, this has required stopping the process and removing the instruments. iTHERM TrustSens reportedly omits that.
The award was presented at the opening of Hannover Messe 2018 in front of guests including Germany’s Chancellor Angela Merkel. The Hermes Award is reportedly one of the most respected technology contests worldwide and recognizes products and processes characterized by innovation, efficiency and application benefits.
