A bayonet fastening cap and a compression spring are included with the adjustable spring thermocouple probe; the bayonet cap can be adjusted on the spring to facilitate site process connection.
Features Of Adjustable Spring Thermocouple Probe:
To make field process connection easier, the Adjustable Spring Thermocouple Probe’s bayonet cover may be adjusted on the spring. The spring is compressed and secured with the bayonet cover once the sensor has been inserted into the adapter. This process can be applied to single or double J, K, E, T, and N thermocouples. The Adjustable Spring Thermocouple Probe’s primary benefit is its ability to be pushed against a surface, which increases accuracy and reduces response time.
