    摘要: There is disclosed an internally switched multiple range transducer. The transducer employs a plurality of individual pressure sensors or Wheatstone bridges fabricated from semiconductor materials and utilizing piezoresistors. Each sensor is designed to accommodate accurately a given pressure range, therefore, each sensor is selected to provide an output when an applied pressure is within its accommodated range. As soon as the pressure exceeds the range, then another sensor is employed to produce an output. Each of the sensors, or each separate transducer, is coupled to a switch or other device to enable the selection of one of the plurality of sensors to operate within its given pressure range when the applied pressure is in that range. In this manner one obtains pressure measurements with a high degree of accuracy across a relatively large pressure range.

    摘要: There is disclosed an apparatus for measuring multiple pressures within different pressure ranges. The apparatus contains multiple pressure sensors which are positioned on a housing, where each pressure sensor is adapted to measure pressure within a different pressure range. The housing has an input port which is constructed to communicate with different output ports, where the output ports communicate with each different pressure sensor utilized in a different pressure range.

    摘要: There is disclosed apparatus for measuring multiple pressures within different pressure ranges. The apparatus contains multiple pressure sensors which are positioned on a housing, where each pressure sensor is adapted to measure pressure within a different pressure range. The housing has an input port which is constructed to communicate with different output ports, where the output ports communicate with each different pressure sensor utilized in a different pressure range. The input port has a stepped or keyed aperture which is adapted to receive different pressure adapters to assure that, for example, only a high pressure will be applied to the high pressure sensor during high pressure measurements. By selecting another adapter, a mid-range pressure and a high pressure will be applied to the pressure sensors during the measurement of a mid-range pressure. By receiving a different adapter, a low pressure will be applied to all the pressure sensors during low pressure measurement. In this manner, one is assured that the pressure sensors are operated without damage to the diaphragms during all pressure measurements. It is of course noted that while three pressure ranges are indicated, there can be more than three or at least two pressure ranges can be accommodated within the common housing. As indicated, the common housing has an input port which consists of contiguous varying diameter sections to enable the selective insertion of various adapter members as indicated where each adapter member can only be inserted within the input port to a desired position, where at that position, the pressure applied to the input port will be directed to the proper sensor.

    摘要: A hermetically sealed displacement sensor has strain gauges placed on thin flexible triangular shaped beams of a load beam cell. The strain gauges are enclosed in a hermetically sealed cavity which cavity is sealed by means of a cover plate placed over the load beam cell. The thin beams are connected together by a center hub and basically form two constant moment beams. There is a top isolation diaphragm member which is convoluted and to which a force is applied which applied force is transmitted to the thin flexible beams. The beams deflect and the sensors produce an output proportional to strain. The sensors on each beam are two in number wherein one sensor is placed in a longitudinal direction with respect to the beam while the other sensor is in a transverse position. The sensors may be wired to form a full Wheatstone bridge or half bridges may be employed. The electrical output from the strain gauge bridge is proportional to the deflection of the center of the sensor.
