Thermowell

Measuring temperature is a crucial part of any industrial process system operation. Unfortunately, thermometers are not designed to withstand especially harsh environments. All thermometers are susceptible to damage from flow, corrosion, abrasion, temperature, pressure, and turbulence, whether they are mechanical (i.e. bimetal or gas actuated thermometers) or electrical (i.e. thermocouples or resistance temperature detectors). A thermometer that is damaged could cause safety issues, contribute to leaking media, or halt production to even the largest of manufacturing plants.

A thermowell serves as a protective barrier between a thermometer and the process media. Thermowells are often found in industrial process systems within refineries and petrochemical and chemical plants. In addition to protecting thermometers, thermowells provide easier serviceability and reduce operating costs.
