teflon sleeved thermowellTemperature measurement is a critical component in any industrial application. While thermocouples and thermometers are the main instruments used to sense temperature, in various applications, they do not have the capability to survive in extreme environments. Damage to these devices can happen through abrasion, corrosion and pressure, to name a few factors. Thermometers that do not work to their potential, can cause safety hazards, as well as interrupting the process of the industrial/ manufacturing application.

In these harsh circumstances, a thermowell is used as a shield between the thermometer and the solid, liquid or gas it is in contact with. Chemical applications are the main processes that thermowells are often used.

In simple terms, a thermowells job is to act as a protective barrier, by allowing the thermometer to be inserted into the thermowell, while still being able to accurately measure temperature. The benefit of this, is that the thermometer is now able to resist corrosion and abrasion, as well as pressure and other factors.

Thermowells are placed along the outer materials of the manufacturing systems, which do not need to be removed. This makes removing, repairing, calibrating or replacing the thermometer an efficient process. When the thermometer is taken out, the thermowell is still connected. The benefit of this is that operations are not disturbed, which could be a costly issue.

thermowell types

With the use of a thermowell, thermometers last longer as they are not directly exposed to the harsh processes, and therefore are protected. By using thermowells in these kinds of environments, it decreases the need to buy thermometers, which in turn, decreases business process costs.
