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： 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 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.

摘要： A beam load cell transducer is positioned between a stationary member and moveable member. The stationary member, as well as the moveable member are surrounded by a collar, which collar has an inner surface means to limit the movement of the moveable member of the transducer. By limiting the movement and restraining further movement after a predetermined excessive force is applied, one stops the beam and therefore prevents the beam from fracturing or rupturing. In the unlikely event that the beam does fracture or rupture, then the sleeve acts to hold the entire unit together, thereby maintaining integrity to the transducer.
