Endress+Hauser has launched the iTHERM TrustSens TM371 compact thermometer for the food, beverage and life sciences industries. It features unique sensor technology with fully automated inline self-calibration function for hygienic and aseptic applications.
100% compliance – 0% effort
The new iTHERM TrustSens TM371 (also available as imperial version TM372) enables continuous, traceable monitoring thanks to its fully automated inline self-calibration function without process interruption, which results in improved product safety, increases plant availability and helps reduce risk and costs. The hygienic thermometer is designed for users in the pharmaceutical, and food and beverage industries, which require absolute compliance with FDA and/or GMP regulations.
At the heart of the temperature probe is a unique sensor unit consisting of a primary Pt100 temperature sensor and a highly accurate integrated reference with long-term stability. The reference sensor uses a physical fixed point on the basis of the Curie temperature and therefore serves to calibrate the primary sensor. The self-calibration is triggered fully automatically at a temperature of 118°C (Curie point of the integrated reference), a process typically occurring during each steam sterilisation (SIP) of the plant. This ensures that the constantly high measuring accuracy of the temperature sensor is permanently monitored throughout its entire life cycle.
Heartbeat Technology in temperature measurement
The integrated smart electronics feature varied diagnostics functions, which are categorised in line with the NE107 NAMUR recommendation and transmitted via HART communication. Furthermore, status signals are indicated locally by means of the LED integrated in the device. In addition to the automated calibration, and therefore verification of the thermometer’s measuring accuracy, data from the last 350 calibrations is stored directly in the device. This makes it possible to access device and process history, which can be used as a basis for predictions and the early determination of trends. These features guarantee continuous, fully autonomous device self-diagnostics. The iTHERM TrustSens is therefore ready for Industrie 4.0 applications.
The TM371 is supplied ex-works with a calibration certificate for the fixed-point reference integrated in the sensor, which ensures the traceability of the calibration chain to the ITS-90 International Temperature Scale. Years of extensive load tests over many thousands of cycles, both in the lab and in the field, have confirmed that the solution is well developed.
The device also has the following international approvals and certificates: Hygienic guidelines in accordance with EHEDG, ASME BPE, FDA, 3-A, 1935/2004, 2023/2006, 10/2011, CE, CRN, TSE, CSA General Purpose.
Significant advantages for the life sciences and food and beverage industries
The self-calibrating TrustSens technology is a major innovation especially in the strictly regulated GMP environment. In addition to a clear rise in process reliability thanks to the self-calibration before every new batch, the availability of the plant is also significantly increased. This in turn results in an immense potential for reducing effort and costs, as well as a higher production yield. Due to the expected high frequency of calibration cycles, the iTHERM TrustSens also enables an unprecedented level of process transparency. Audit-compliant calibration data is available for complete documentation at all times: a valid calibration certificate can now be produced with a simple mouse click (e.g. with the Endress+Hauser FieldCare software).
Led by iTHERM TrustSens, Endress+Hauser now offers a complete, globally available range of products for temperature measurement technology, system products and services, specially developed for the hygienic and aseptic requirements of the pharmaceutical, and food and beverage industries. The comprehensive port-folio, consisting of compact, modular and highly precise thermometers, secure data managers and process display units, fulfils even the most demanding requirements in these industries.
