PCB fault detection

PCB fault detection and analysis: the system has two pressure tanks, one on top and the other on the bottom, separated by a pneumatic shut-off valve in the middle. The pressure tank is equipped with two probes, one at the top of the tank and the other at the bottom of the pot. Used to detect the position of the steel lens of the pressure vessel, the probe into the tank, the measurement, and the amplification circuit in the pressure tank.
