are contained in the gauge. One of these coils is
connected directly to the battery, producing a constant
magnetic field. The other coil produces a variable field,
whose strength is determined by a rheostat-type tank
unit. The coils are placed 90 degrees apart.
A pressure gauge is used widely in automotive and
construction applications to keep track of such things
as oil pressure, fuel line pressure, air brake system
