WRN-630 conical thermocouple protection tube station dedicated thermocouple

Thermocouple 1 power plant, for the application of professional power plant designed to meet the 300,000, 600,000 kilowatts generating units and auxiliary equipment required temperature. Direct measurement of the range of -200 ° C ~ 800 ° C of the production process of the liquid, vapor, gas and solid surface temperature. 2, the working principle of the thermocouple electrode composed of two different conductor materials. When measuring side and reference junction temperature difference, it will generate thermoelectric power, work thermoelectric power meter will show the corresponding temperature value. Thermal resistance is the use of material changes in temperature, its resistance changes with the characteristics to measure the temperature. When the resistance changes, the working resistance of the meter will show the corresponding temperature value. 3, the main technical parameters Product performance standards IEC584 IEC751 IEC1515 JB / T18622-1997 JB / T8623-1997 GB / T16839-1997 4, measuring range and tolerance Graduation number tolerance level I II Temperature range ° C Tolerance Value Tolerance Value Temperature range ° C WRN K ± 1.5 ° C -40 ~ + 375 ± 2.5 ° C -40 ~ + 333 ± 0.004ltl 375 ~ 1000 ± 0.0075 ltl 333 ~ 1200 WRM N ± 1.5 ° C -40 ~ + 375 ± 2.5 ° C -40 ~ + 333 ± 0.004 ltl 375 ~ 1000 ± 0.0075 ltl 333 ~ 1200 WRE E ± 1.5 ° C -40 ~ + 375 ± 1.5 ° C -40 ~ + 333 ± 0.004 ltl 375 ~ 800 ± 0.004 ltl 333 ~ 900 WRF J ± 1.5 ° C -40 ~ + 375 ± 1.5 ° C -40 ~ + 333 ± 0.004 ltl 375 ~ 750 ± 0.004 ltl 333 ~ 750 WRC T ± 1.5 ° C -40 ~ + 125 ± 1 ° C -40 ~ + 133 ± 0.004 ltl 125 ~ 350 ± 0.0075 ltl 133 ~ 350 5, temperature insulation resistance thermal resistance at ambient temperature of 15-35 ° C, relative humidity less than 80%, the test voltage of 10-100V (DC ) insulation resistance between the electrode and the jacket pipe> 100MΩ.
