The IFM TN2445 is a precision-engineered temperature sensor designed for reliable monitoring of liquids and gases in industrial automation. Featuring an extended probe length, advanced communication capabilities, and robust electrical design, it delivers highly accurate results in demanding process environments.

At the core of the TN2445 is its Pt1000 resistance temperature detector (RTD), manufactured to DIN EN 60751, Class A standards. This sensing element ensures high accuracy, minimal drift, and long-term stability, making it suitable for critical temperature monitoring tasks. Whether used for heating, cooling, or process control, the TN2445 provides consistent measurements essential for maintaining product quality and process efficiency.

The sensor’s threaded G 1/2 external process connection with a 150 mm installation length makes it ideal for applications requiring deeper immersion into process media. The extended probe length is particularly advantageous for larger pipelines, tanks, and vessels where precise thermal readings depend on penetration into the fluid stream rather than surface-level detection. This design ensures accurate monitoring even in dynamic or variable flow conditions.

A standout feature of the TN2445 is its IO-Link communication interface. IO-Link enables advanced digital connectivity, including remote parameterization, real-time diagnostics, and simplified system integration. This functionality provides operators with improved process transparency, supports predictive maintenance, and allows for quick commissioning and configuration adjustments directly through the control system.

Electrically, the TN2445 is designed for industrial-grade reliability and safety. It operates on a supply voltage of 18…32 V DC, ensuring compatibility with standard automation systems, and is certified for use with a cULus Class 2 power source for compliance with North American safety standards. The inclusion of gold-plated contacts further enhances durability by improving conductivity and protecting against corrosion, ensuring consistent signal transmission even in challenging environments.

The TN2445 is suitable for use with both liquids and gases, providing flexibility across a wide range of applications. Typical uses include temperature monitoring in hydraulic circuits, compressed air systems, process water loops, heating and cooling lines, and chemical processing systems. Its rugged build and extended probe length make it especially well-suited for applications where conventional sensors may not reach the process medium effectively.

In summary, the IFM TN2445 is a robust and high-accuracy temperature sensor that combines an extended 150 mm probe, Pt1000 Class A sensing element, IO-Link connectivity, and reliable electrical design. Built for long-term use in industrial automation, it ensures precise monitoring of liquids and gases, while offering the added advantage of advanced digital integration for smarter and more efficient process management.
