Oil Pressure Gauge: Description and Operation
Oil Pressure Gauge
The oil pressure gauge consists of two intersecting coils wound around a permanent magnet rotor. Applying voltage to the coils through fuse 7 generates
a magnetic field causing the rotor to rotate and the gauge needle to move. The magnetic field is controlled by the sender. As the resistance in the sender
varies, current through the gauge coils changes. The resulting fluctuation in the magnetic field then moves the gauge needle accordingly.
