Critical Technical Advantages
-
Hygienic Design and Certification: The TMR35 is engineered for cleanability, carrying both 3-A marking and EHEDG certification. This ensures that the sensor body and its process connections are free of dead legs and crevices, preventing bacterial growth and ensuring safe Clean-in-Place (CIP) operations.
-
Ultra-Fast Thermal Response: Thanks to the integrated thin-film Pt100 element, the TMR35 features extremely short response times. This is vital for monitoring rapid temperature changes in pasteurizers, heat exchangers, or aseptic filling lines.
-
Integrated Programmable Electronics: The device can be specified with a built-in 4 to 20 mA transmitter that is fully PC-programmable. Using the free ReadWin 2000 software, users can scale the measuring range or adjust the failure mode signals according to NAMUR NE43 standards.
-
Accuracy in Small Pipes: The TMR35 maintains high measurement precision even with very short insertion lengths. This allows for accurate temperature tracking in small-diameter sanitary tubing (DN15/DN25) without significantly obstructing the flow of the product.
-
Robust Stainless Steel Housing: The entire housing is constructed from high-grade stainless steel with a surface finish optimized for hygienic environments. Its robust build is resistant to high-pressure washdowns and aggressive sanitizing agents.
-
Marine and Industrial Versatility: In addition to its hygienic credentials, the TMR35 holds marine approval, making it suitable for specialized maritime applications that require a sanitary-grade sensor.
