摘要： A single pressure sensing capsule has a reference pressure ported to the rear side of a silicon sensing die. The front side of the silicon sensing die receives a main pressure at another port. The silicon sensing die contains a full Wheatstone bridge on one of the surfaces and within the active area designated as the diaphragm area. Thus, the difference of the main and reference pressure results in the sensor providing an output equivalent to the differential pressure, namely the main pressure minus the reference pressure which is the stress induced in a sensing diaphragm. In any event, the reference pressure or main pressure may be derived from a pump pressure which is being monitored. The pump pressure output is subjected to a pump ripple or a sinusoidally varying pressure. In order to compensate for pump ripple, one employs a coiled tube. The tube length is selected to suppress the pump ripple as applied to the sensor die. In this manner, the pump ripple cannot cause resonance which would result in pressure amplification and which pressure amplification would destroy the sensor.

摘要： An accelerometer includes a cantilever mass with a thin beam element between the mass and the fixed end of the accelerometer. The end of the mass is tapered. A limiting member has an aperture that is tapered corresponding to the taper at the end of the mass and positioned to surround the tapered end of the seismic mass. The beam accelerometer as well as the limiting member is placed in a cylindrical housing whereby the limiting member is moved along the taper of the seismic mass to adjust the spacing between the limiting member and the inner wall of the housing to thereby adjust the amount of movement of the seismic mass. In one embodiment the aperture of the tapered limited member also surrounds the seismic mass but the gap between the inner wall of the tapered limiting member and the outer wall of the seismic mass is adjusted to determine the amount of movement of the beam. In this manner, one can utilize a beam accelerometer arrangement of a cylindrical configuration within a housing and whereby the seismic mass has a taper and the taper coacts with a limiting member which has a corresponding taper to adjust the distance that the beam can move upon application of a force thereto.

摘要： A high pressure transducer has an H shaped cross-section with a center arm of the H having a top and bottom surface with the top surface of the H accommodating four strain gauges. Two strain gauges are located at the center of the top portion of the center arm of the H and are positive strain gauges, while two strain gauges are located near the periphery of the center arm of the gauge. The bottom surface of the center arm of the gauge has an active area of a smaller diameter than the circular diameter of the center arm portion of the transducer. The smaller active area is surrounded by a thicker stepped area which surrounds an active area on the pressure side of the H shaped member. The surrounding stepped area enables one to position the two negative strain gauges on the opposite surface of the center arm and near the periphery to thereby cause the negative gauges to respond to a negative stresses and therefore to enable one to provide a full Wheatstone bridge which includes the two positive strain gauges located at the center of the center arm of the H and the two negative peripheral gauges.

摘要： There is disclosed a multiple axis load cell or controller in which axial and torsion measurements are decoupled while maximizing the outputs of both measurements. The active member of the load cell is a wheel with dual beams as the spokes. The wheel thus has four spokes or four beam members, each spoke is a pair of rectangular cross-section beams, orthogonal to each other. The beams have strain gages on the wide surfaces which measure the bending strain which is proportional to torsion or the axial input. There is an inner beam section and an outer beam section associated with each spoke and orthogonal to each other. The outer beams have the wide surface normal to the axis of the load cell. This beam section is more sensitive to the axial tension/compression input. The inner beam sections have their wide surface parallel to the axis of the load cell and are much less sensitive to bending but are sensitive to torsion. Therefore when a torsion or twisting motion is applied to the load cell, the inner beams with their wide surface parallel to the axis of the wheel are more sensitive and bend more. These beams experience bending as a result of the torsion input and have strain gages formed in a Wheatstone bridge arrangement to provide an output proportional to the torsion. The outer beams also have gages mounted thereon which are also wired in a Wheatstone bridge configuration and which Wheatstone bridge output of these gages are proportional to the axial force.

摘要： A joystick apparatus employs a hermetically sealed load cell having strain gauges placed on flexible beams formed on the load cell. All of the strain gauges are on the same surface of the load cell and therefore wiring is performed on a single side of the load cell. The strain gauges are enclosed in hermetically sealed cavity. The sensing diaphragm consists of a concentric thick inner and outer section joined by thinner diametrically opposed beam elements. The thin beam elements are compliant members which can deflect. Each beam includes strain gauges or sensor elements and the load cell is coupled to a joystick which when moved causes the beams to deflect to cause the sensor elements to produce an electrical output proportional to the force and direction of the joystick. The sensor can yield an output proportional to any angle over the 360° movement of the joystick to provide outputs proportional to the X and Y positions of said joystick. Thus, the joystick arrangement can resolve any angle or force into X and Y components for full directional control.
摘要翻译：操纵杆装置采用密封的称重传感器，该测力传感器具有放置在测力传感器上形成的柔性梁上的应变仪。所有的应变计位于测力传感器的相同表面上，因此在测力传感器的单侧进行接线。应变计封闭在密封的空腔中。传感膜片由同心厚的内部和外部部分组成，该部分与较细直径相对的梁元件连接。薄梁元件是能够偏转的柔顺构件。每个梁包括应变计或传感器元件，并且测力传感器耦合到操纵杆，当操作杆被移动时，导致梁偏转以使传感器元件产生与操纵杆的力和方向成比例的电输出。传感器可以产生与操纵杆360°运动的任何角度成比例的输出，以提供与所述操纵杆的X和Y位置成比例的输出。因此，操纵杆装置可以将任何角度或力分解成X和Y部件以进行全方位控制。

摘要： A high pressure transducer has a metal housing with a main inlet high pressure port at one end and a reference pressure port at the other end. The ports communicate with a central hollow of the housing. Positioned in the hollow and communicating with the main inlet port is a first header welded to the housing and containing a first sensor device. Also positioned in the hollow and communicating with the reference pressure port is a second header also welded to the housing and having a second sensor device. There is another high pressure port on the housing and located between the inlet and reference ports to receive a main inlet high pressure as applied to said main inlet port and when a reference pressure is applied to said reference port. The applied pressures cause the first header weld to experience zero stress due to the application of the same main pressure to both the main inlet port and another pressure port. The second header weld experiences a weld pressure equal to the difference between the main high pressure and the reference pressure.
