A Complete Guide for a Bimetal Thermowell

Global Precision Instruments (GPI Instruments) provides high quality and performance. It is an ideal choice the time, accurate temperature measurement is a top most priority. The Bimetal Thermowell are recommended in order to get the dampened movement protected otherwise, that could result from the contact with pressurized, corrosive, flowing, viscous, or abrasive process fluids.

Even they also enable removal of the bimetal thermometers for replacement or service without affecting the entire process.


This type of Bimetal Thermowell meets the high requirements of this process industries. In the industries of chemical, petrochemical, oil and gas, power engineering and shipbuilding, the temperature measuring instrument manufactured from stainless steel is in use.


  • 304 stainless steel construction standard and 316 stainless steel also available.

Technical data

1/2 inch female NPSM straight pipe thread for the mechanical joint standard. Along with that female G1/2B connection also available.

Other protection

However, the high ingress protection and liquid damping, operation under high vibration condition of the Bimetal Thermowell is possible.

The model is there to satisfy the high requirements of the resistance that is against the aggressive media. In order to allow the optimum fitting of the process, individual insertion lengths along with the different process connections can be selected.
