SENSOR WITH ADJUSTABLE PRESSURE RESPONSIVE DETECTION AND CONTROL BY TOMMY L. GRAY "Abstract of the Disclosure" A fluid pressure gauge type pressure responsive gauge drive having a drive to a sensor controller system with sensor controllers actuatingly engaged at respective adjusted pressure limits with gauge movement travel unimpeded by sensor controller contact in the range of movement between sensor controller pressure limit position settings. The drive may be connected to drive a fluid pressure gauge needle over an indicating dial and upper and lower pressure limit setting needles are adjustable to desired settings over the indicating dial . Calibration structures are provided for a coordinated setting of the gauge dial drive and in the drive of the sensor controller system calibrating each gauge structure for the "C" type bourdon tube installed. Fly open type activated block and bleed valves are used as sensor controllers mounted on cam adjusted pivotally-mounted upper pressure and lower pressure individual sensor controllermounting plates pivoted about a common pivot center that is the pivot center for the sensor controller activating arm. Further, a fluid pressure differentialactivated relay is shown useable in combination with the sensor controllers in a combined system.
