Thermocouples (RTDs) for power station temperature measurement are mainly used to measure the temperature of steam pipelines and boilers, employing a combination of protection tube and sheathed thermocouple (RTD). Users can weld or mechanically fix the protection tube to the equipment, then insert the sheathed element to operate, which not only increases the working pressure and service life but also facilitates maintenance or replacement. The products are available in five structural forms: thermowell type, air duct and flue duct type, high pressure, medium pressure and low pressure, and can be selected according to temperature, pressure and steam flow rate.

- Protection tube machined as a single piece using deep blind hole technology, with no welding at the end, for higher strength and longer service life
- Sheathed element adopts a spring-loaded structure, maintaining good contact with the measuring end of the protection tube during operation
- Vibration-resistant, reducing thermal response time
- Sheathed element adopts an insulated design to prevent electromagnetic interference, ensuring stable and accurate measurement
- Protection tube can be welded or mechanically fixed; the sensing element is easy to service and replace
Temperature measurement of main steam piping in power plants
The protection tube and sheathed element combination withstands high-temperature, high-pressure steam erosion, and supports servicing or replacement of the sensing element during operation.
Temperature measurement of boiler air ducts and flue ducts
The air duct and flue duct type structure is used for flue gas temperature monitoring under 0～1000℃ and flow velocity ＜9 m/s conditions.
