The junction box is used in conjunction with the thermocouple to measure the temperature. How to avoid the fluctuation of thermocouple measurement data
Move?
Take the average value of temperature readings to reduce data fluctuation. In addition, it is also necessary to ensure that the on-site wiring is correct and reasonable. Most thermoelectric
The couple is a floating signal source with low common mode voltage, so a bias current path is needed to ground the scxi module amplifier. Indeed
Ensure that the negative pole of each floating thermocouple is grounded through a resistor. For information on impedance values, refer to the phase of the junction box
Close the document. For grounded thermocouples, make sure that the ground point of the thermocouple does not have a high common mode voltage.
