ABSTRACT:
A gauge assembly (10) is disclosed which incorporates 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 (92, 94, 96) extending from a contact plate (58) on the pointer assembly (52) resiliently engage a point (91) along a resistive element (84). The ends of the resistive element (84) form first and second contacts (86, 88) while the point (91) of contact between the contact arms and resistive element is connected to a third contact (90) to form a voltage divider circuit.
