Center justified gauge
First Claim
1. An apparatus for displaying the level of a sensed parameter in a center justified format, comprising:
- a sensor means for producing a sensor signal having a value representative of the level of a sensed parameter, said sensor signal having a reference value;
a gauge means for displaying the level of said sensed parameter, said gauge means having a plurality of high indicating segments, a plurality of low indicating segments, and a central segment, said plurality high and low indicating segments and said central segment being illuminable; and
instrument means for receiving said sensor signal and responsively displaying the level of the sensed parameter in the center justified format by illuminating said central segment and progressively illuminating said plurality of high and low indicating segments in response to the value of said sensor signal substantially increasing and decreasing from said reference value, respectively.

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.
