Faria Faria Euro White 2" Oil Pressure Gauge - 80PSI

Euro White Oil Pressure Gauge 2" - 80 PSI 2" - Hole Size: 2.0625" (53mm) A pressure gauge works by sending a low amperage current through the gauge. the indicators to ground through a sending unit with variable resistance. The resistance of the sending units increases or decreases with changes in pressure, temperature, etc... As the resistance varies. from the sender, the amount of current allowed to flow through it to ground changes and the gauge deflects, showing the change in pressure Benefits: Anti-scratch glass lens Plastic enclosures for corrosion resistance and long life 12 VDC negative ground Can be adapted for 24 VDC systems br/>Available in standard or metric values
