Abstract
A differential pressure sensor with a compensation means, said differential pressure sensor comprising the diaphragm with a first means having a mass mounted upon the diaphragm. The first means is utilized to determine the position of the diaphragm relative to an initial first position and/or to increase the effective area of the diaphragm. A housing contains the diaphragm, the housing has a first and a second inlet port. The first inlet port provides a first pressure to a first side of the diaphragm and the second inlet provides a second pressure to the second side of the diaphragm, the diaphragm moving to the lesser of the two pressures. A counterweight mechanism is located in the housing having a inner arm and an outer arm. The counterweight mechanism pivots about an axis. The center of gravity of the counterweight mechanism is located on the outer arm. The inner arm is in contact with the first means, whereby the counterweight mechanism compensates for the mass added to the diaphragm which enables the pressure sensor to be mounted in any orientation.
