ABSTRACT:
A gauge assembly (10) utilizing a voltage divider circuit to provide reliable and accurate measurement of a fluid level within a tank (16) or other environment. A pointer assembly (52) pivots about an axis (42) in response to a moving float to indicate the fluid level. A plurality of contact arms (114, 116, 118) extending from a contact plate (58) on the pointer assembly (52) resiliently engage a point (120) along a resistive element (88). The first end of the resistive element is connected to a voltage regulator (100) which is connected to a first contact (94). The second end of the resistive element forms a second contact (96). The point (120) of contact between the contact arms and resistive element is connected to an amplifier (102) which is connected to a third contact (95) forming a low impedance voltage divider circuit.
