2" Oil Pressure Gauge - 80 PSI - Euro White2" - Hole size: 2.0625" (53mm)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, etc...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.Benefits:Anti-scratch glass lensPlastic Cases for corrosion resistance and long life12 VDC negative groundCan be adapted for 24 VDC systemsAvailable in standard or Metric values
