Depending on configuration
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.
