Description
Faria Kronos 2" Oil Pressure Gauge 80 PSI with stainless steel trim. 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.
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
Requires a Faria Oil Pressure sender, not included
