American Thermowell weld-in thermowells are designed for high pressure and/or high flow process applications

Weld-in thermowells are highly recommended in applications that produce a high rate of flow or pressure, since the thermowell is welded directly to the process pipe without the need for threads or flanges. This type of thermowell is also recommended when contaminants could collect in exposed threads, such as pharmaceutical or food processing production.

Our weld-in thermowells are designed and manufactured 100% in house, and are made to accept standard and custom made thermometers, thermocouples, bulbs and RTD’s.
