    摘要： A service gauge for determining refrigerant pressure and the saturated vapor equivalent temperature, or other parameters, for a refrigerant in an HVAC system. In one embodiment, the service gauge employs a bourdon tube with at least one attached strain gauge to sense the refrigerant pressure and produce an electronic pressure signal. In another embodiment, a magnet and rotary position sensor produces an electronic signal proportional to the refrigerant pressure. The electronic pressure signal from the output of the strain gauge or the rotary position sensor is connected to a microprocessor, which calculates and displays the refrigerant pressure, the saturated vapor equivalent temperature for a variety of refrigerants, produces instantaneous and time lapsed representations of those parameters, and other parameters of the refrigerant.

    摘要： A device for determining the weight of vehicle occupants or objects on vehicle seats is proposed, which has two elements interconnected via a spring arrangement. A position sensor is also provided to determine the position of the first element in relation to the second element. The first element can tilt about a fulcrum. The position sensor is arranged in relation to the longitudinal extension of the second element in a position which is predefined by a perpendicular projection of the fulcrum onto this second element.

    摘要： A pressure sensor includes a sensor body which is arranged to couple to a process pressure. The sensor body has a magnetic property which changes as a function of pressure applied by a process fluid. A sensor is coupled to the sensor body and is configured to measure pressure of fluid in the sensor body as a function of a change of magnetic property of the sensor body.

    摘要： A target adapted for use in a magnetomechanical transducer system is activated by an ac magnetic field and a variable dc bias field to produce a resonant frequency which corresponds to the effective strength of the dc bias field. The target includes an elongated ductile strip of magnetostrictive ferromagnetic material enclosed in a nonmagnetic container in a manner to allow the strip to vibrate freely. The strip has a magnetomechanical coupling factor, k greater than O, where K=zero.sqroot.(1-fr.sup.2 /fa.sup.2), fr and fa being the resonant and antiresonant frequencies, respectfully. The system is economical to construct and affords accurate and efficient measurement of pressure via displacements and angles of pressure sensitive devices at locations proximate to or remote from the signal source (target).
