Abstract: An inductive flow meter has a measurement channel body with an electrically insulating inner wall and defining a flow channel that extends along a longitudinal axis. A pair of electrodes is exposed to said flow channel at its inner wall so as to be in contact with a medium flowing within said channel, and are diametrically opposed to each other in a transverse plane perpendicular to the longitudinal axis. A pair of magnetic pole shoes of a magnetic field generating system is arranged on opposite sides of the measurement channel body and centered about the transverse plane containing the electrodes, with the shoes adapted to generate a magnetic field across the flow channel section, such that lines of the magnetic field extend essentially perpendicular to both the longitudinal axis and a straight line between the electrodes. Two associated, electrically conductive signal lines extend between the electrodes and associated connector lugs on an outer surface of the measurement channel body.

Abstract: An improved magnetostrictive torque sensor for sensing torque applied to a shaft that is rotatably supported in a housing. A magnetostrictive cylinder is fixed to the shaft. A stator is supported on the shaft by bearings to surround the magnetostrictive cylinder and is accommodated in the housing. The stator incorporates exciting coils and detecting coils such that the coils are located about the shaft. The magnetosttrictive cylinder is strained by torque applied to the shaft. The exciting coils generate flux running through the magnetostrictive cylinder. The generated flux is changed in accordance with the strain of the magnetostrictive cylinder. The detecting coils detect the flux changes. The stator is also rotatably fixed to the housing by bearings. Rotation of the stator relative to the housing is prevented by connectors that couple the stator with the housing. This prevents tension in wires that lead from the stator.

Abstract: A magnetoelastic torque sensor for providing an output signal indicative of the torque applied to a member about an axially extending axis of the member, comprising, a first ferromagnetic, magnetostrictive region in the member, the region being magnetically polarized in a single circumferential direction and possessing sufficient magnetic anisotropy to return the magnetization in the region, following the application of torque to the member, to the single circumferential direction when the applied torque is reduced to zero, whereby the ferromagnetic, magnetostrictive region produces a magnetic field varying with the torque. Magnetic field sensors are mounted proximate to the ferromagnetic, magnetostrictive region and oriented with respect thereto to sense the magnetic field at the sensors and provide the output signal in response thereto.

Abstract: The stand free multi-beamed load cell for accurately monitoring and registering weight changes has at multiple beams secured to one another to form a polygon rim with an open center. Multiple tabs are equally spaced from one another along the rim to receive securing members to secure the rim to a support surface. Each tab has a pair of balancing members on either side of the securing member to maintain the rim above the support surface. At least one of the beams has a bridge to reduce the depth of the beam to enable flexing under application of the weight. A strain gage proximate the bridge registers the flexing of the beams, sending the signals through an electronic connector to a control means. The balance members serve to minimize the deflection on the rim approximate the tabs, creating maximum strain level at the bridge. The tabs and balance members further serve to accommodate for any variations in the support surface.
