Spring-loaded thermocouples are used in temperature applications where the sensor is used in a thermowell for protection from the process medium. Shown here with 4" 304 stainless steel well and white polypropylene head.
Allow 2-3 weeks for delivery on made-to-order temperature sensors. If you need your thermocouple assembly faster, please call for expedited delivery options.
A thermocouple consist of two different electrically conductive metal alloys. Together, they produce a voltage that’s proportional to the temperature difference between either end of the pair of conductors. Combinations of specific alloys produce a predictable difference between temperature and voltage (e.g., Type J thermocouples, made of copper and constantan, have a range of 32° to 559°F with a standard error range of ±4°).
- Provided with 304 stainless steel thermowell and head mount fittings
- Spring-loaded thermocouple assemblies with wells and connection heads built to meet your exact requirements
- Good for process temperatures to -328° to 2300° F
- For lengths longer than 24" or dual element thermocouples, call Lesman.
