摘要： A sensor is configured to sense pressure in an isolated or subterranean environment. The sensor is configured to act as a capacitor with a capacitance that varies as a function of pressure. The sensor has a robust design with minimal moving parts, and in which any parts that do move do not communicate electrically through direct electrical conduction (e.g., through conductive leads). Instead, moving parts that participate in the performance of sensor as a capacitor receive and dispense electrical charge only through a dielectric fluid (e.g., a gas or liquid within the sensor). This may reduce hysterysis, lag, and/or friction with respect to pressure-dependent capacitor designs in which wiring is connected directly to moving parts.

摘要： Exemplary systems and method are directed to a sensing device, and to a pressure sensing system and method. An exemplary method includes supplying electromagnetic energy to a transducer which is configured to reflect the electromagnetic energy at a ring frequency determined by an inductance of the transducer, wherein the inductance changes in response to compression of the inductive element. The ring frequency of electromagnetic energy reflected by the transducer is correlated to a pressure value.

摘要： A differential pressure switch comprising an enclosure including a peripheral wall and a solid one-piece non-perforate partition wall that is integrally attached to the peripheral wall around the entire perimeter of the partition wall. The enclosure includes a sensor chamber located on a first side of the partition wall and a fluid cavity located on a second side of the partition wall. The partition wall and the integrally attached peripheral wall seal the sensor chamber in fluid-tight leak-proof isolation from the fluid cavity. A flexible diaphragm is located within the fluid cavity and forms a low-pressure fluid chamber on one side and a high-pressure fluid chamber on a second side of the diaphragm. A magnet is located in the fluid cavity and is coupled to the diaphragm such that the magnet changes position in response to movement of the diaphragm. A Hall effect sensor is located in the sensor chamber. The sensor is adapted to sense the magnetic force generated by the magnet and thereby detect the distance between the magnet and the sensor. The sensor indicates when the magnet is located a predetermined distance from the sensor such that a predetermined differential in pressure exists between the pressure of the fluid in the low-pressure fluid chamber and the pressure of the fluid in the high-pressure fluid chamber.

摘要： A differential pressure transducer includes a pair of interior chambers separated by a peripherally supported, nominally planar electrically conductive diaphragm. A magnetic assembly is positioned on at least one chamber wall opposite to a central portion of the diaphragm. The magnetic assembly includes an electrical conductor and preferably a magnetic field permeable electric field shield between the electrical conductor and the chamber so that as the central portion of diaphragm is displaced from its nominal plane in response to an applied pressure differential, the inductance of the magnetic assembly changes. The transducer may be a portion of a tank circuit of an oscillator having a frequency of oscillation that varies with the pressure differential applied across the diaphragm.

摘要： The present invention is a displacement sensor, which is capable of keeping high sensing resolution even if the amount of displacement of the core and the amount of changing the inductance are small. In the displacement sensor of the present invention, a displacing body is capable of displacing according to external force. An LC resonance circuit includes a magnetic coil and a core made of a magnetizable material, which is capable of moving close to and away from the magnetic coil according to the displacement of the displacing body. An oscillator inputs continuous signals having prescribed frequency to the LC resonance circuit. A detecting circuit detects the amount of the displacement of the displacing body on the basis of amplitude of the continuous signals from the LC resonance circuit.
