Endress+Hauser TM402: Hygienic, Robust Thermometer
The Endress+Hauser iTHERM TM402 is a robust and highly accurate thermometer designed specifically for the demanding hygienic and aseptic applications within the Food & Beverages and Life Sciences industries. This instrument offers a perfect balance of reliability, precision, and compliance with the most stringent international standards, making it an indispensable tool for critical temperature measurement tasks. Its sturdy construction, advanced measurement technology, and comprehensive certification profile ensure consistent performance and product safety. The TM402 stands out as a premium choice for processes requiring absolute integrity and repeatable accuracy in sensitive environments.
Precision for Food and Beverage
The TM402 brings precision for food and beverage processing, ensuring optimal product quality and safety. Its design is tailored for use in hygienic and aseptic applications, where contamination control is paramount. The thermometer’s robust 316L material construction, combined with surface roughness options down to 15 µin (0.38 µm), minimizes bacterial growth and facilitates thorough cleaning-in-place (CIP) and sterilization-in-place (SIP) processes. This makes it ideal for monitoring temperatures in pasteurization, fermentation, sterilization, and chilling processes, ensuring compliance with strict industry regulations and contributing to superior product integrity and consumer health.
Uncompromised Quality, Certified Compliance
The TM402 offers uncompromised quality, certified compliance with a range of international hygiene standards. It proudly holds certifications such as 3-A®, EHEDG, ASME BPE, and FDA, alongside a TSE Certificate of Suitability. Furthermore, its assembly meets PMO requirements as a recording thermometer by the US FDA for dairies, highlighting its suitability for the most critical dairy applications. This extensive list of approvals ensures that the TM402 can be confidently integrated into validated processes, providing verifiable adherence to regulatory requirements and peace of mind for operators in highly regulated industries.
Versatile Process Connection Options
With versatile process connection options, the TM402 seamlessly integrates into any existing setup. It supports a wide array of hygienic connections, including Tri-clamp, various clamp connections according to ISO2852, G3/4″ and G1″ Liquiphant, and Varivent. This broad compatibility minimizes the need for costly modifications or adapters, ensuring quick and efficient installation. The design ensures secure, leak-free connections that maintain the hygienic integrity of the process, preventing ingress of contaminants and safeguarding product purity. This adaptability makes the TM402 a flexible and future-proof investment for dynamic production environments.

Wide Operating Range, Robust Design
The TM402 features a wide operating range, robust design suitable for demanding industrial conditions. It accurately measures temperatures from –50 to +200 °C (–58 to +392 °F) and can withstand process pressures up to 40 bar (580 psi) at 20 °C. Its protection class up to IP69K signifies its extreme resistance to dust and high-pressure, high-temperature washdowns, a common requirement in hygienic environments. The choice of 316L stainless steel for the protection tube and thermowell, along with available outer diameters of 1/4″ (6.35 mm) and 3/8″ (9.53 mm), ensures long-term durability and reliability, even in harsh operating conditions.
Direct Immersion, No Thermowell Needed
Designed for direct immersion, no thermowell needed, the TM402 simplifies installation and optimizes response time. By directly immersing the sensor into the process, it eliminates the need for a separate thermowell, reducing potential contamination points and improving measurement accuracy and speed. This configuration, featuring a fixed, non-exchangeable insert and imperial-style design, ensures robust performance and consistent measurement in various applications, from small tanks to large process lines. This direct contact approach is critical for applications where rapid and precise temperature readings are essential for process control and safety.
Advanced Integration with Head Transmitter
The TM402 supports advanced integration with head transmitter options, enhancing its functionality and connectivity. It can be integrated with a head transmitter offering a 4-20 mA output with HART communication, allowing for seamless integration into modern control systems. This capability provides enhanced diagnostics, remote configuration, and reliable data transmission, crucial for efficient process management and predictive maintenance. This intelligent integration elevates the TM402 from a simple thermometer to a smart sensor, capable of contributing to a more connected and optimized industrial environment, ensuring data integrity and system reliability.
