ABSTRACT:
Gauges are often used to monitor operating conditions on machines. Advantageously, such gauges are capable of indicating the level of a parameter being either above or below a reference level. The subject invention provides a sensor for producing a sensor signal having a value representative of the level of a sensed parameter. A gauge displays the level of the sensed parameter and includes a high indicating segment and a low indicating segment. An instrument receives the sensor signal and progressively illuminates the high and low indicating segments in response to the sensor signal increasing or decreasing from a reference value, respectively.
