The heat is on

Temperature control is important in many processes in the food & beverage industry – not least for the German manufacturer Walter Rau Neusser Öl und Fett AG. The company produces vegetable-based fats and oils that are used to manufacture food products such as ice cream and baked goods. One of the many state-of-the-art processes involves heating freshly pressed cooking oils under vacuum in order to remove volatile components and dissolved gases from the oil. If the process temperature is too high, it can impair the product.


Endress+Hauser TrustSens

Groundbreaking technology: TrustSens temperature sensors perform self-calibrations during operation.

Temperatures that are too low keep the product from being properly purified. To date, the sensors had to be calibrated after each product and batch changeover. This enormously time-consuming step now belongs to the past thanks to the iTHERM TrustSens thermometer from Endress+Hauser. It’s the world’s first thermometer capable of self-calibration while the process is running. By deploying the iTHERM TrustSens, Walter Rau Neusser Öl und Fett AG eliminated roughly 3,000 process interruptions per year, in addition to the same number of technician service calls.
