Thermocouple head

A thermocouple head serves as a sealed protective housing for the terminal connections of an assembled thermocouple. It contains ceramic or Bakelite terminal blocks used to connect the thermocouple core wires to external compensation cables.

Electrical Connection: Ensures organized wiring and stable transmission of thermoelectric potential signals, while eliminating issues such as loose connections and signal drift.
Physical Protection: Shields internal terminals from environmental hazards—including dust, moisture, oil, corrosive fumes, and molten material splashes—preventing damage caused by harsh operating conditions.

Thermocouple heads are used in:
1. Chemical, petroleum, and energy industries:
Applications include pipeline temperature monitoring, reaction vessels, and oil & gas facilities. Explosion-proof junction box models are available to meet on-site safety regulations.
2. Standard waterproof applications:
Prevents the ingress of liquids, oil, and water, which could otherwise compromise the stability of the temperature-sensing element.

Thermocouple heads can be matched with the appropriate materials and protection ratings based on operating temperature, explosion-proof requirements, medium corrosiveness, and mounting thread specifications.
Customization options include multi-angle cable outlets, extended housings, special thread types, and integrated transmitter mounting cavities; rapid prototyping and reliable delivery times are available.
We offer complete assembly packages—including junction boxes, thermocouples, plugs, and various heaters—providing a single-source procurement solution that reduces purchasing and coordination costs for customers.
