Product Overview

The TM4531 is engineered for accurate temperature measurement in process equipment, tanks, vessels and pipelines. Its Pt100 measuring element provides stable resistance-based temperature sensing across a broad industrial range. The 100 mm probe length enables effective temperature measurement where deeper insertion into the medium is required. The hygienic process design supports applications where cleanable and corrosion-resistant components are important. The sensor can be connected to suitable evaluation units for centralized process monitoring.

Temperature Measurement

The sensor provides a measuring range of -40 to 150 °C, supporting both low-temperature and elevated-temperature industrial processes. The Pt100 Class A element is designed according to DIN EN 60751 for dependable measurement accuracy. A typical dynamic response of T05/T09 = 1/3 seconds enables the sensor to react quickly to process temperature changes. The 6 mm probe diameter provides a practical balance between mechanical strength and response speed. This configuration is well suited to continuous temperature monitoring.

Process Integration

The G 1/2 external threaded connection with sealing cone allows the sensor to be installed into compatible process adapters and fittings. The 100 mm installation length provides extended immersion into tanks and pipework. The M12 connector simplifies electrical installation and maintenance in industrial control environments. Gold-plated contacts support dependable electrical connection performance. The sensor can be paired with suitable evaluation equipment for temperature indication, control and monitoring.

Performance & Reliability

The stainless-steel construction provides strong mechanical resistance for industrial installations. Wetted parts use stainless steel with an electropolished surface suitable for hygienic applications. IP68 and IP69K protection helps protect the sensor against water, dust and intensive cleaning conditions. The sensor is designed for ambient temperatures from -25 to 80 °C. Shock and vibration resistance support reliable operation in industrial equipment.

Diagnostics & Maintenance

The M12 connection allows convenient disconnection during inspection and service operations. The RTD design provides a straightforward resistance-based sensing principle that can be evaluated using compatible equipment. Proper process mounting helps maintain measurement stability and sealing performance. Regular inspection of the process connection can help prevent mechanical or sealing-related issues. The robust stainless-steel construction supports long-term operation with appropriate process maintenance.
