Surface Thermocouple (Thermal Resistor)
Product Overview
Section titled “Product Overview”Surface Thermocouple (Thermal Resistor) is used for temperature measurement on boiler tube walls, furnace walls, pipelines, and other cylindrical surfaces. It uses components with a diameter of 3-6 mm as the temperature probe. The measuring end can be assembled with a temperature-sensing piece and fixed to the measured surface by welding, screws, magnets, or hoops.
For curved measurement points such as furnace walls and pipelines, the temperature-sensing piece can be shaped to match the measured surface for contact temperature measurement.
Applications
Section titled “Applications”- Boiler tube wall temperature measurement.
- Furnace wall temperature measurement.
- Temperature measurement on pipelines and other cylindrical surfaces.
Product Advantages
Section titled “Product Advantages”- For curved-surface temperature measurement: the temperature-sensing piece can conform to furnace walls, pipelines, and other cylindrical surfaces.
- Multiple fixing methods: welding, screws, magnets, and hoop fixing to suit site installation conditions.
- Different response characteristics: for the boiler wall thermocouple, thermal response time is not greater than 0.85 s for Shell Type and not greater than 2.5 s for Insulation Type; for the hoop thermocouple, it is not greater than 2 s for Shell Type and not greater than 6 s for Insulation Type.
- Multiple graduations and sleeve diameters: K, N, and E graduations, with sleeve diameters of Phi4, Phi5, and Phi6 mm.
Installation Method
Section titled “Installation Method”- Weld the temperature-sensing piece to the equipment.
- Fix the temperature-sensing piece to the equipment with bolts.
- Fix with magnets.
- Fix with hoops.
For the boiler wall thermocouple, the technical parameter table lists welding or bolting; the hoop thermocouple uses hoop fixing.
