Industrial use as a measuring device type thermocouple temperature sensor, and temperature transmitters usually display instruments, recording instruments and supporting the use of electronic regulator. It can be measured directly from a variety of production processes within 0 -1800 degree celsius of liquid, vapor and gases and the solid surface temperature.
According to state regulations, the company began producing in 1997 found, EC number of international standards for sub-degree B, R, S, K, E, J, T, N types of assembling, unified design-type thermocouple.
* Nominal Pressure Thermocouple
Generally refers to the working temperature protection tube can withstand a static external pressure without rupture. In fact, allow the pressure of work not only with the protection tube material, diameter, wall thickness, but also its structure, installation, placement depth and measured the velocity and type of media and so on.
* Minimum insertion depth of the thermocouple
Protection tube should be not less than the diameter of 8-10 times (except special products).
* Thermocouple insulation resistance (at room temperature)
Temperature insulation resistance test voltage DC 500Vi 50V, measuring insulation resistance of the atmospheric conditions at room temperature for the temperature 15-35 degree celsius, 45% relative humidity, atmospheric pressure 86-106KPa.
* Work
Thermocouple works are: Two different components of the conductor ends, welded to form a loop, called the direct measurement of temperature-side end, called the reference terminal-side end. When the measurement side and the reference-terminal temperature difference, heat will be generated when the loop current, connected to the display meter, the meter pointed out that the heat generated by electric thermocouple corresponding temperature.
Thermocouple measuring the thermal electromotive force will end with the growth temperature and thermal EMF of the thermocouple conductor size and material, and only two ends of the temperature difference, and hot electrode length and diameter has nothing to do.
Fabricated mainly by the thermocouple junction box, protection tube, insulation tube, terminals, thermal electrode, the basic structure, and with a kind of fixed device component.
