Faria 2" Heavy Duty Oil Pressure Gauge - 80 PSI - Black Dial & SS Bezel - 24004

2" Heavy Duty Oil Pressure Gauge - 100 PSI - Black Dial & SS Bezel

A pressure gauge operates by sending a low amperage current through the gauges' meter to the ground via a sending unit with variable resistance. The resistance of the sending units increases or decreases 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.

Features:

  • Anti-scratch glass lens
  • Plastic Cases for corrosion resistance and long life
  • 80 PSI
