Pressure gauge with digital display

A measuring instrument for use with a gas compression system that includes a plurality of sensors each measuring one of a plurality of operating parameters, each of the sensors delivering a signal indicative of the measured parameter to a sensor bus, the measuring instrument comprising:

• a housing including a rear panel and a wall extending from the rear panel to define an instrument space;
• a face including measurement indicia and an aperture, the face coupled to the wall and spaced apart from the rear panel to enclose the instrument space;
• a mechanically-operated pressure sensor positioned within the instrument space and including an indicator that is movable with respect to the face and that cooperates with the measurement indicia to indicate a measured pressure;
• a circuit board disposed within the instrument space and electrically connected to the sensor bus;
• and
• an electronic display disposed within the instrument space and visible through the aperture, the electronic display connected to the circuit board and operable to display data related to the plurality of operating parameters.
