摘要： A pressure sensor probe has a first port connectable to a relatively low pressure source in a compressor crankcase and a second port connectable to a relatively high pressure source at the output of an oil pump. A shuttle is slidably disposed in a bore and has a first end which closes the first port when the difference in pressure between the two ports indicative of normal operation exceeds a selected value determined by the relative areas of the shuttle exposed to the respective pressures and by a coil spring which biases the shuttle away from the first port. A passage is formed between the shuttle and the bore leading from the second port to a force receiving surface on the high pressure side of the shuttle. The length and cross sectional area of the passage is selected to provide a desired dampening or time delay between the high pressure source and the force receiving surface. Indicator means responsive to the position of the shuttle is used to indicate the status of the oil differential between the two ports and, if desired, to control the actuation of the compressor motor.

摘要： A liquid filled differential pressure detector comprises two pressure sensors. Each sensor is constructed of one or more capsules, which are pairs of diaphragms sealed at their peripheries. The innermost diaphragms are interconnected by a tube which contains a rod assembly. The interior of the sensors and interconnection tube form a sealed volume filled with a incompressible liquid. The rod assembly contacts the outermost diaphragm of the sensors and is displaced by expansion and contraction of the capsules caused by a differential pressure change against the outer surface of the sensors. The motion of the rod assembly is transformed into an electrical signal to indicate the pressure measurement. The apparatus is symmetrical about the center point of the tube to reduce error caused by the fluid's thermal expansion by causing equal and opposite forces to cancel, thereby preventing motion of the rod assembly. An overpressure condition results with one sensor completely collapsing with one diaphragm bottoming out against the other, but causes no damage to the capsules due to complementary facing of the diaphragm pairs. The compliance of the diaphragms is chosen to be small enough to cause any gaseous bubbles to be driven into solution during the initial prepressurization of the fluid, ensuring its incompressibility. In a second embodiment, the rod assembly is replaced with a core assembly located at the midpoint of the tube, suspended in a magnetic fluid which separates the incompressible fluid into two identical volumes. The motion of the core assembly, which is due purely to the displacement of the incompressible fluid, is transformed into an electrical signal to indicate a pressure measurement.

摘要： A pressure-measuring transducer device for transforming a change of tested pressure into a change of output signal frequency. Variable reluctance sensing elements and an FM IC block are assembled together in a base. The transducer device can have a variety of configurations and external forms and is sturdy and reliable, tightly sealed, interference resistant, and adapted for use in measuring dynamic and static pressures of different mediums. The pressure transducer has a piston type double film, and the base is made of aluminum alloy and is "honeycombed". The specific gravity is approximately equal to that of soil. It is adapted for measuring soil pressure or boundary soil pressure of reinforced concrete structure and pressure of loose solid substances. An alternate embodiment is used for measuring pore pressure in soil. Several forms of filtering devices are provided. A liquid pressure transducer can be used for measuring liquid pressure in liquid and for measuring positive or negative pressure in gas, if the filtering device is removed.

摘要： The present invention is a remote system for indicating tire pressure which includes a mechanical electromagnetic pressure sensor which is disposed outside a pneumatic tire which is mounted on a wheel rim. The mechanical electromagnetic pressure sensor includes a bellows which is fluidly coupled to the pneumatic tire through the wheel rim and a ferrite rod which is fixedly coupled to the bellows. The mechanical electromagnetic pressure sensor includes a pointer which is mechanically coupled to the bellows and indexing plate which provides a linear scale of the position of the pointer, the indexing plate is disposed adjacent, but not contiguous to the pointer so that the scale of the indexing plate mechanically provides a direct and visual reading of the pressure in the pneumatic tire. The remote system also includes a passive circuit having a first coil which is mechanically coupled to the wheel rim and a second coil which is electromagnetically coupled to the ferrite rod, which is slidably coupled to the second coil, all of which are electrically coupled to form a tuned circuit which resonates at a particular frequency which is dependent on the position of the ferrite rod. The remote system also includes a probe which detects the change in frequency at which the passive circuit resonates in order to provide a measure of movement of the ferrite rod in response to the change in pressure of the pneumatic tire.

摘要： The transducer device disclosed herein is designed for measuring the pressure of a moving fluid stream. The device includes a body member with a lengthwise bore therein and a pressure orifice in communication with the bore. Positioned in the bore is a one-piece piston consisting of a rod segment, a first stem segment extending from one end of the rod, a base segment at the opposite end of the rod, and another stem segment which extends from the base. The base is slideable in the bore of the body and there is an annulus section between the rod segment and the bore. A linear spring means is fitted over the rod, such that it occupies the annulus section. Ahead of the first stem is a sensor unit, which connects into a pressure indicator, for visually indicating pressure values. In operation, the body is mounted on a structure, such as a transfer line, which carries a fluid under pressure. The pressure orifice is in direct communication with the pressurized fluid, so that any change in the fluid pressure causes the sensor unit to produce an electrical signal. This signal is picked up by the indicator and displayed as units of pressure.

摘要： A pressure responsive control device having a housing carrying a flexible diaphragm therein that cooperates with the housing to define a pressure chamber therein that is adapted to receive a variable pressure that acts against the diaphragm to position the diaphragm relative to the housing in relation to the value of the pressure, the diaphragm being operatively interconnected to a plunger that follows movement of the diaphragm. The control device has a transducer operatively associated with the plunger to produce an electrical signal in relation to the position of the plunger, the transducer comprising a core carried by the plunger in axially aligned relation therewith and an induction coil carried by the control device and receiving the core therein. A range spring is carried by the housing and is operatively interconnected to the diaphragm to tend to oppose movement of the diaphragm in one direction of movement thereof. The range spring has one end bearing against a calibrating member and the other end bearing against an annular shoulder of the plunger. The induction coil is carried on a spool-like member that has an externally threaded portion, the calibrating member being threaded to the threaded portion to provide for calibrating movement thereof.

摘要： A compensated measurement system utilizing dual sensing elements (10, 12) and a single variable frequency oscillator (14). A common operative association between the sensing elements (10, 12) and the oscillator (14) is achieved by multiplexing. Temperature and supply voltage variations are compensated by generating an output (f.sub.0) which is proportional to the ratio of the two generated frequencies (f.sub.1, F.sub.2).

摘要： Liquid flow sensing apparatus which in the illustrative embodiment is used to sense an occluded vein (cessation of blood flow). A flexible pressure pillow is connected in the blood flow line and is inserted into a housing in contact with a metallic leaf spring. The position of the leaf spring is adjusted relative to an eddy current proximity sensor so that the sensing apparatus is calibrated to a no-alarm position during proper blood flow. If blood flow ceases, the flexible pressure pillow contracts thereby moving the leaf spring away from the eddy current proximity sensor and an alarm condition is thereby detected.
