Thermocouples for temperature measurement in power stations

Thermocouples (resistors) are used for temperature measurement in power plants, specifically for measuring the temperature of thermocouples and thermal resistors. 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, division number, temperature measurement range, ℃, accuracy level, allowable deviation △ t, nickel chromium nickel silicon WRNTK0~800 Ⅱ, 2.5 ℃ or 0.75% t, nickel chromium copper nickel WRETE0~600 Ⅱ, 2.5 ℃ or 0.75% t, copper copper nickel WRCTTT-40~350 Ⅱ, 1 ℃ or 0.75% t, platinum resistance WZPTPt100~200~500B level (0.30+0.005 | t |), copper resistance WZCTCu50~100 Ⅱ (0.30+6.010-3t). Note: t is the measured temperature of the temperature sensing element, and for platinum resistance and copper resistance, 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, and flow rate of the measured medium .....
