Self-calibrating RTD temperature sensor in UHT processes Increase process safety and product quality
In UHT processes the product is heated to above 135 °C to kill as many microorganisms as possible withthe aim to increase the shelf life of the end product. Accurate and reliable temperature control is crucial to avoid negative effects on the taste and product quality, making periodic calibration of the installed temperature sensors necessary. iTHERM TrustSens is the first self-calibrating compact thermometer that calibrates automatically whenever the process temperature drops below 118°C (244.4 °F).
