The remote pressure gauge shows normal readings on-site, but sometimes it displays negative values when the data is transmitted to the computer
A remote pressure gauge transmits the pressure signal to the display instrument through a potentiometer. Vibrations of the pressure gauge can cause changes in the resistance value of the potentiometer, affecting the accuracy of measurements; it is therefore necessary to check whether there is any vibration, whether the potentiometer is loose, and whether the slider makes good contact with the winding resistor...
