Sensor Assemblies with Thermowells

A thermowell protects the temperature sensor from process conditions, such as pressure and flow-induced forces, and chemical effects. Proper temperature element protection starts with the selection of the thermowell or protection tube.

Conditions that influence the selection include the temperature, pressure, flow velocity, pipe size, insertion length, and the process environment and medium. All of these variables are applied in the ASME PTC19.3 TW 2016 Standard that SSi uses to ensure that every thermowell is designed properly. A variety of materials and process connections are available for thermowells including:

• Standard and exotic materials
• Flanged, threaded, welded, and sanitary process connections
• Straight, step-down, or tapered designs
• Hastelloy, Monel, Nickel, 316SS, Carbon Steel, and other material options
