Wear resistant thermocouple
1、 Application
It is suitable for power plant ball mill, coal mill, cement kiln head, kiln layer and other occasions where the protective tube is seriously worn. It is used to measure the temperature of the medium with serious abrasion in the measuring devices such as fluidized bed roaster and coal feed path
2、 Main technical parameters
1. Measurement accuracy: class I (± 1.5 ℃ or ± 0.4% ∣ t ∣ ℃)
2. Temperature measurement range: 0-1300 ℃ (range can be adjusted according to the scale of sensor)
3. Diameter of armored element: Φ 6 or Φ 8mm
4. Material of outer sleeve: corundum tube, gh3039, nct301 or nct601
5. Electrical outlet: m20x1.5, npt1 / 2
6. Hardness of wear head: hrc62-65
7. Protection grade: IP65
3、 Features
The thermocouple has the advantages of long service life, good shock performance, high heat conductivity, oxidation resistance, thermal shock resistance, high temperature resistance, scouring resistance, no nodulation, no slagging, convenient installation and use. The protection tube greatly enhances the service life of the thermocouple, which is unmatched by stainless steel metal, ceramic protection tube and high aluminum materials in the market.
1. High chromium cast steel drilling, high temperature, impact and wear resistance;
2. Diameter optional to meet the requirements of various kiln aperture, fast reaction function, strong stability;
3. Any optional length of protection tube;
4. It can be used without preheating;
5. Various installation methods (direct insertion, screw fixation, movable flange, fixed flange);
6. With digital display meter, it can be displayed locally;
7. It can be built-in transmitter, output 4-20mA, long-distance transmission current signal, reduce the error caused by wire transmission;
8. Wide temperature range, stable and reliable operation.
