The TrustSens TM371 temperature sensor features unique technology that provides fully automated inline self-calibration without process interruption.
The new sensor’s self-calibration function saves time and costs by converting a normally manual exercise into a fully automated procedure. By self-calibrating, the instrument reduces the need for calibration equipment, such as portable heat sources, and their maintenance costs. It also saves resource time as site engineers aren’t needed to perform the task of calibration, freeing their time for other activities on site.
iTHERM TrustSens for hygienic and aseptic applications.
This unique sensor contains both an accurate PT100 temperature element and a separate, highly stable reference located at the probe tip. When the instrument observes 118°C as part of a cooling cycle, a temperature typically seen during SIP cleaning, the measured temperature is compared against the neighbouring reference to check its accuracy.
By automating its calibration procedure, TrustSens can also help to reduce the risk of product wastage caused by incorrect temperature measurement. As self calibration during each SIP clean would lead to more frequent calibrations, any drift of the inbuilt temperature sensor would be quickly detected rather than waiting to be discovered during the next manual calibration cycle.
At the same time, an audit-compliant calibration certificate is digitally produced and stored within the temperature probe, ready to be downloaded at any time across HART communication using the free Endress+Hauser DeviceCare software or the more advanced FieldCare software. With capacity to store up to 350 entries, it is possible to access a long calibration history of your TrustSens instrument
Designed for use in hygienic and aseptic applications within the life sciences and food & beverage industries, TrustSens is also fully compliant with FDA and GMP guidelines. Each calibration is traceable to the ITS-90 International Temperature Scale, and each TrustSens unit is supplied ex-works with a calibration certificate showing this calibration chain.
