Shanghai WeiLian Electronics develops and produces T25 series wear -resistant thermocouples uses plasma spraying technology, high chromium cast iron, and Kesh alloy different materials, which greatly improves wear resistance and extend the flow. The service life and expand the range of fluidity testing. It is suitable for the recycling of circulating vulcanized bed boilers, ball mills, circulating fluidized beds, boiling furnaces, cement rotating kiln tail smoke rooms, coal mills and cement companies, smelting companies, etc. Sensor Protecting severe occasions for wear.

The T25 series is composed of a wear -resistant head, connecting rod, and a fixed thread or flange, a wiring box, armoelectric core, or armoelectric puppet.

The wear -resistant material of the T25 series of abrasion -resistant thermocouples does not affect the temperature stagnation response speed, which extends the service life of circulating fluidized bed boilers for two years.

The T25 series of wear -resistant thermocouples use composite armor technology to add wear -resistant particles with high -temperature alloy matrix to make precision melting casting. The protective sleeve has the advantages of abrasion resistance, high temperature resistance, vulcanization resistance, liquid iron powder, limestone and other cement materials, anti -punching, vibration resistance, antioxidant and other advantages. Use temperature 800 ~ 1200 ℃.

T25 series wear -resistant thermal electric puppet model


The external protective tube of the T25 series armor -type temperature sensor is stainless steel, which is full of high -density oxidative substance insulators, with strong anti -pollution and excellent mechanical strength and insulation performance. It is less diameter than the assembly temperature sensor, bending, small thermal inertia, fast thermal response time, good shock resistance, long service life, and good flexibility. It is suitable for installing the prefabricated temperature sensor that cannot meet the occasions where the requirements and the environment are harsh.
