In numerous applications, it is neither desirable nor practical to expose a temperature sensor directly to a material. Wells are therefore used to protect against damage corresion, arosion, aborsion and high pressure processes. A thermo well is also useful in protecting a sensor from physical damage during handling and normal operations.Materials used in thermo wells:

  1. Stainless steel
  2. Inconel
  3. Monel
  4. Alloy Steel
  5. Hastelloy
