摘要： A monitoring system for monitoring a plurality of functions and conditions on a plurality of gauges or display modules. The monitoring system comprises a plurality of sensors (10) each producing a sensor signal in response to sensing of one of a function and a condition; a control device (12) coupled to the plurality of sensors and producing a control signal responsive to each of the sensor signals, the control signal including sensor data information and associate sensor identity information identifying one of the plurality of sensors (10); a plurality of display modules (20) each being programmable and each being coupled to the control device (12); and a plurality of module overlays (58) with one of the plurality of module overlays (58) being coupled to each of the plurality of display modules (20). Each of the plurality of module overlays (58) has module identification means (22) communicating with the display module (20) on which it is mounted to program the display module (20) to be responsive to the control signal when the sensor identity information in the control signal corresponds to the module identification means (22) to cause the display module (20) to display the associated sensor data information.

摘要： A variable capacitance dual pressure sensor for sensing the pressure levels of a pair of fluids independently comprises an enclosure having a top wall and a bottom wall, and a substrate of dielectric material having a first major surface facing the top wall and a second major surface facing the bottom wall. A first electrode is affixed to a portion of the first major surface and a second electrode is affixed to a portion of the second major surface. A first flexible electrically conductive diaphragm is sealed to the first major surface of the substrate and is spaced from the first electrode to form therewith the plates of a first capacitor and a second flexible electrically conductive diaphragm is sealed to the second major surface of the substrate and is spaced from the second electrode to form therewith the plates of a second capacitor. The first and second diaphragms are electrically coupled together to form a common connection. The substrate is sealably mounted within the enclosure forming therewith a first chamber external to the first diaphragm for receiving a first fluid and a second chamber external to the second diaphragm for receiving a second fluid.
