Thermocouple is a temperature sensing element, essential accessories in coal quality analytical instruments gelatinous layer analyzer, nickel-chromium - nickel silicon thermocouple; length: 130mm, temperature range :0-1300 degree; thermocouples installed correctly very important, silicon carbide tube plugged into the encounter down fallback 2mm farther from the instrument display value lower than the actual oven temperature delay liters less than the set temperature (actual oven temperature has already reached) or rise to the set given ℃, poor control precision, dozens or even Baidu fluctuations up and down in temperature control point: if the the thermocouple touch in silicon carbide tube, when to rise to the high temperature, the leakage current by silicon carbon tube fleeing into the machine within the display temperature fluctuations, a straight line under the swap or even negative temperature take back (with thermocouple temperature caused decreased Negative separate temperature zones), a serious Jihuai instrument temperature part of the circuit. Abnormal temperature control, furnace temperature is too high (much higher than 1050 ° C) phenomenon: see to the furnace, is not the normal red, but had been white, often resulting the quartz boat diameter pipe adhesions serious the diameter pipe burning bend diameter pipe with silicon carbon tube adhesion phenomenon exit into the coal samples found that coal ash has been melted in a porcelain boat can not be scraped, visual reality to adjust the the thermocouple location or adjust set given temperature. If the thermocouple is not connected or internal disconnecting the instrument display overrange: If the thermocouple short circuit, the instrument is always displayed at room temperature. . During the trial, when the the gas large number of precipitation from coal bottom of the cup, from time to time to the heating element hair, burned gas and carbon black precipitate from the bottom of the cup, in order to avoid a short circuit burned silicon carbide, nickel-chromium wire or affect thermocouple work properly.
