Thermocouple Temperature Probe
Advantages of Wepower Electronic thermocouple temperature probe: Cold And Heat Resistant, Waterproof And Oil-Proof, Corrosion And Wear Resistance, High Accuracy .
Type J, K, S, E, or T Thermocouple Temperature Probes are supplied with grounded thermocouple components that are welded into the sheath’s tip. To create a fully sealed, integrated junction, the sheath and conductors are welded together (see photo below). There are several types of probes available, including surface fixing, prick bending, rigid sheath with threaded fittings, adjustable spring, and rigid sheath.
Sheathed thermocouple temperature probes can directly measure the temperature of liquid, vapor, gas medium and solid surface in various production processes.
