ABSTRACT:
A pressure gauge assembly for aircraft tires and the like having a helical coil bourdon tube sensor capable of indicating a pressure differential between a monitored source of pressure and a calibrated reference source of pressure. The reference pressure is applied to one surface of the bourdon tube coils while the monitored pressure is applied to the other surface of the coils. The resultant movement is a linear indication of any pressure differential. A valve assembly can be provided with the pressure gauge assembly to permit fluidic access to the monitored pressure. If the volume of the monitored pressure is variable such as an aircraft tire, the secondary source of calibrated pressure can be provided with a predetermined pressure relative to the normal tire pressure to compensate for any volumetric changes in the tire during operation. In an alternative embodiment, the bourdon tube can be used to monitor the pressure in a fire extinguisher for indicating any leaks. Advantageously, dials are provided for a visual inspection to determine a go or no-go situation. Finally, the pressure gauge can be temperature compensated by providing the calibrated pressure source with a fluid having substantially the same pressure temperature response characteristics as the fluid in the monitored pressure chamber.
