Product details

Thermocouples (resistors) for temperature measurement in power stationsThermocouple and thermistor temperature measurement for power plants. In order to catch up with the international advanced level and save foreign exchange for the country, our company has successively introduced professional manufacturing technology and equipment from abroad. Based on the original products, we have widely listened to the opinions of design institutes and power station users, and referred to the EBASCO specifications in the United States to redesign the products, adding new varieties, so that the entire supporting series of varieties and specifications fully meet the supporting needs of domestic or imported 300000 and 600000 kilowatt generator sets and other domestic units, and meet the market with excellent quality.

range

category code name graduation mark Temperature measurement range ℃ accuracy class Allowable deviation △ t
Nickel chromium nickel silicon WRNT K 0~800 ± 2.5 ℃ or 0.75% t
Nickel chromium copper nickel WRET E 0~600 ± 2.5 ℃ or 0.75% t
Copper Copper Nickel WRCT T -40~350 ± 1 ℃ or 0.75% t
rtd WZPT Pt100 -200~500 Grade B ±(0.30+0.005|t|)
Copper resistance WZCT Cu50 -50~100 ±(0.30+6.0×10-3t)

Note: "t" represents the measured temperature of the temperature sensing element, while for platinum and copper resistors, it is the absolute value of the measured temperature of the temperature sensing element.

Nominal pressure: generally refers to the static external pressure that the protective tube can withstand at room temperature without breaking, and the test pressure is generally 1.5 times the nominal pressure. In fact, the allowable working pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to its structural form, installation method, insertion depth, as well as the flow rate and type of the measured medium.

The maximum current measured through a platinum resistor shall not exceed 5mA
