Heavy-Duty 2" Oil Pressure Gauge (80PSI) - Black
Perimeter-lighted black dial with bold white graphics, black aluminum SAE style bezel, contoured white pointer, and flat glass lens.
A pressure gauge operates by sending a low amperage current through the gauges's meter to ground via a sending unit with variable resistance. The resistance of the sending units increase or decrease with the changes in pressure, temperature, ect.
As the sender's resistance varies, the amount of current allowed to flow through it to ground changes and the meter deflects, showing the change in pressure.
Available for MG systems, J1939 CAN Bus or J1939 Stand-Alone systems and mechanical types.
