Because the signal is low thermocouples for microvolt, if you are using long distance signal attenuation and interference environment of strong coupling of electricity, enough to make a thermocouple signal distortion, resulting in inaccurate measurement and control of temperature compensation KX conductor cause severe temperature fluctuations in control. According to our experience, usually thermocouple wire length control within 15 meters better compensation wire KX much money, if more than 15 meters, we recommend using a temperature transmitter to transmit signals. Temperature transmitter is to convert the temperature corresponding to a direct current potential value transmission, strong anti-drop problem long-distance transmission wires, due to higher input impedance in thermometer, thermocouple thermoelectric power generated (millivolts) transmission Current (micro A level) is very small, the voltage drop across the wire with little loss KX compensation wire parameters, in general, KX compensation wire manufacturer, within the error range. Therefore, thermocouple transmitter, thermocouple input signal, output 4-20ma, this can not compensate for the wire to be long-distance transmission of the KX compensation wire _ Anhui Global Market (certified) _KX compensation wire by the Anhui GSM meter line Cable Limited.
