Display thermocouple, with seismic, explosion-proof, high pressure resistance, quick thermal response time, strong durability and other advantages, as a temperature sensor is usually used with display instrument, recorder and electronic voltage regulator. Can directly measure the surface temperature of various liquids, vapors, gases and solids. It is especially suitable for installation in places where the temperature is especially miniaturized, the pipeline is narrow and bent, and the response speed is fast. Temperature sensor specifications: 1. The temperature range of use: K (- 50 ~ 1300 ° C), S (50 ~ 1700 ° C), T (200 ~ 350 ° C),E (0 ~ 800 ° C), J (0 ~ 1000 ° C), B (300 ~ 1800 ° C), N (0 ~ 1300 ° C) PT100: -200 to 500℃ for Class A, -200 to 600℃ for Class B Cu50 ( -50 ~ 150℃ ) , Cu100 ( -50 ~ 150℃ ) 2. Use the 2/3-wire interface 3. Accuracy from Class I, Class II Features: 1. High precision and good stability; 2. High sensitivity and good linearity; 3. Short response time and good compatibility; 4. Compact structure, easy installation, good waterproof performance
