iTHERM ModuLine TT131 Welded Thermowell

Brand: Endress+Hauser
Extended Extended

This thermowell designed according to DIN 43772 guarantees a high resistance to most industrial process environments. It is made from pipe or tube and is available in a wide range of diameters and materials. A specially designed thermowell tip ensures fast response times for a more efficient process control. Oversheaths in PTFE or tantalum can withstand extremely corrosive process conditions. It is offered with a variety of process connections: flanges, threads, weld-in or compression fittings.

  • Protects the temperature sensor against physical and chemical stress
  • High robustness for challenging process conditions
  • Pressure range: up to 100 bar (1450 psi)
  • For use in pipes, containers or tanks
  • Improved ease of maintenance (sensor replacement without process shutdown) and recalibration of the measuring point
Features
  • Modular configuration according to DIN 43772
  • iTHERM QuickNeck: cost and time savings thanks to simple, tool-free recalibration of the insert
  • Extension, immersion length and total length can be chosen according to process requirements
  • Wide choice of dimensions, materials and process connections available
  • Specially designed tip for fast response times
