Endress+Hauser TW251-G2BE5S00 welded thermowell specifications. 9mm root diameter, 500mm immersion, G1/2" thread, 316L, for temperature sensor protection.

Endress+Hauser TW251-G2BE5S00 Welded Thermowell

The Endress+Hauser TW251-G2BE5S00 is a metric-style welded thermowell designed to protect temperature sensors (RTDs, thermocouples) in industrial process applications. It features an integrated compression fitting for easy sensor replacement and is constructed from 316L stainless steel for corrosion resistance.

Key Features

• Integrated Compression Fitting:​ Allows sensor replacement without process shutdown.

• Welded Construction:​ Robust design for demanding industrial environments.

• Corrosion Resistant:​ 316L stainless steel wetted parts.

• Standard Metric Design:​ Conforms to industry standards for interchangeability.

Important Selection & Installation Notes

1. Probe Compatibility:​ Verify that your temperature sensor (RTD or thermocouple) has a 6mm or 9mm diameter to fit this thermowell.

2. Process Conditions:​ Ensure the process temperature and pressure do not exceed the specified limits. At elevated temperatures, the maximum allowable pressure decreases.

3. Installation:​ Requires proper threading or welding into the process pipe/vessel. Use appropriate sealing methods (PTFE tape, thread sealant) for threaded connections.

4. Compression Fitting:​ The integrated compression fitting requires proper tightening to ensure a leak-proof seal around the temperature probe.

5. Material Compatibility:​ Confirm 316L stainless steel is suitable for your process media to avoid corrosion issues.
