RUKO SMU-DIN382-G1/4x19 Threaded Thermowell, G 1/4, 19 mm Tip, 100 mm Immersion, 316L Stainless Steel

In industrial temperature measurement, a bare sensor exposed to the process medium risks damage from pressure, corrosion, or flow. The RUKO SMU-DIN382-G1/4x19 threaded thermowell provides a robust protective housing for resistance thermometers or thermocouples, ensuring accurate readings and long sensor life in demanding applications.

Who is it for

This thermowell is intended for process engineers, maintenance technicians, and instrumentation specialists in chemical, petrochemical, food processing, and power generation industries. It suits installations where a sensor must be inserted into a pressurized or corrosive fluid while remaining replaceable without process shutdown.

Main features

• Threaded process connection G 1/4 male for direct mounting into tapped holes
• Tip diameter 19 mm with 7 mm bore to accommodate standard sensor probes
• Immersion length 100 mm for adequate contact with the medium
• Manufactured from stainless steel 1.4404 (316L) for high corrosion resistance
• Withstands process pressures up to 100 bar at 20 °C and temperatures up to 600 °C
• Straight cylindrical tip (Form 2) per DIN 43772 design

Tips

Ensure the thermowell material is compatible with the process medium to avoid corrosion. Select an immersion length that places the sensor tip in the zone of representative temperature. Use a suitable thread sealant compatible with the process temperature and pressure.
