Stainless Steel Thermowells with Integral Compression Fitting for 3mm diameter Sensors

view larger image
This range of 316 stainless steel thermowells are of a welded construction with an integral compression fitting and are for use with our 3mm diameter thermocouples or Pt100 sensors. They are ideal for applications where the removal of the sensor could prove complicated such as on a vessel, pipe or tank. They are 6mm O.D. and have a choice of either 1/2” BSPT or 1/4” BSPT process thread with an olive that compresses on to the sensor sheath to hold it in place. A wide choice of immersion depths (under the thread) is available to suit various lengths of temperature sensor as shown.
  • Available in a wide choice of lengths to suit various temperature sensors
  • Male process thread: 1/2” BSPT or 1/4” BSPT
  • Integral compression fitting to suit 3mm diameter sensor
  • Sheath material: 316L Stainless Steel
  • Operating range: -75°C to 800°C
