Our company is a professional manufacturer of the Thermometer, with the continuous development of China's power industry, starved for power plants and thermal resistance of the thermocouple to replace imports. The company in order to catch up with international advanced level, but also for the country to save foreign exchange, has introduced from abroad a professional manufacturing technology and equipment, and products based on the original, listen to the Design Institute and the station user comments, with reference to the United States EBASCO specifications, the product re-design, adding new varieties, so that the whole series of complementary varieties, fully comply with domestic or imported 300,000, 600,000 kilowatt generator set as well as other units supporting the domestic needs and industry with outstanding quality meet the market.

 Category Code No. indexing accuracy level temperature tolerance range ℃ △ t 
 Nickel-chromium - nickel silicon WRNT K 0 ~ 800 Ⅱ ± 2.5 ℃ or 0.75% t 
 Nickel-chromium - copper-nickel WRET E 0 ~ 600 Ⅱ ± 2.5 ℃ or 0.75% t 
 Copper - Copper-nickel WRCT T -40 ~ 350 Ⅱ ± 1 ℃, or 0.75% t 
 Platinum resistance WZPT Pt100 -200 ~ 500 B-class ± (0.30 +0.005 | t |) 
 Copper resistance WZCT Cu50 -50 ~ 100 Ⅱ ± (0.30 +6.0 × 10-3t) 
 Note: "t" for the temperature sensing element measured temperature, and copper resistance for platinum resistance temperature devices, compared with the absolute value of the measured temperature. 

 ● Nominal 

 Generally refers to room temperature, protect the tube can withstand without breaking static external pressure, test pressure is generally used, said pressure of 1.5 times. In fact, the allowable working pressure not only to protect the pipe material, diameter, wall thickness about, but also its structure, installation method, into the measured medium depth, and velocity categories. 

 Platinum resistance by measuring current maximum of 5mA.
