The remote pressure gauge is a relatively simple one in the pressure sensor. There is a potentiometer inside the pressure gauge, and the sliding end of the potentiometer is connected with the pointer of the pressure gauge. When the pressure changes, the position of the sliding end of the potentiometer also changes. When the two ends of the potentiometer in the pressure gauge are connected to the given power supply of the inverter, the voltage between the sliding end and “GND” is the feedback signal XF.

  1. Remote transmission pressure gauge and inverter wiring: The three terminals of the remote transmission pressure gauge are respectively connected to the inverter’s +10V (power supply), GND (common ground), and X1 (multi-function terminal).
    Second, you need to set the parameters of the inverter:
    1, running command source = external terminal
    2, frequency command channel = PID
    3, P value, I value, D value
    4, the upper frequency limit;
    5, the lower frequency limit;
  2. Target pressure; this is the basic parameter of the common inverter connected to the remote pressure gauge to achieve constant voltage control. Specifically, it needs to be extended according to the terminal condition and parameters of the inverter used.
