Product Description:
The Wear-Resistant Cut-Off Thermocouple is a specialized temperature sensor designed for use in highly abrasive and high-temperature industrial environments. It features a rugged, wear-resistant protection tube and a cut-off (or detachable) sensing tip structure that allows for quick replacement without removing the entire thermocouple assembly. This design ensures both longevity and ease of maintenance, making it ideal for demanding process applications.
Working Principle:
This thermocouple operates based on the Seebeck effect: when two dissimilar metal wires are joined at one end (the measuring junction), a voltage is generated that is proportional to the temperature at that junction. The generated signal is transmitted to a monitoring or control system.
Applications:
- Cement plants (rotary kilns, calcination systems)
- Steel mills (sintering, blast furnaces)
- Petrochemical and refinery systems
- Coal and biomass power plants
- Fluidized bed reactors
- Dust-laden or particle-abrasive pipelines
