Abstract: A magnetostrictive wire waveguide type position measuring system wherein the wire waveguide is mounted within a small diameter brass tube which, in turn, is mounted by way of resilient suspension components within a rigid outer tube affixed to a position reference frame. The suspension components isolate the waveguide from relatively high frequency shock inputs characteristic of rough environment applications. The position signal is derived from output signal quantities generated by the propagation times of sonic disturbances from a first reference magnet held in a fixed position relative to the outer housing and a second user magnet which moves relative to the outer housing with the element or quantity being monitored. To compensate for longitudinal movement of the waveguide within the floating suspension system, a computer calculates a variable time delay related to the difference between a constant time quantity and the propagation time of the reference magnet impulse and adds this time delay to the user magnet propagation time. The waveguide terminal ends are gradually reconfigured from round to flat, rectangular sections and sandwiched between acoustic dampening pads to reduce or eliminate sonic reflections. A flexible film piezoelectric pickup is disclosed.

Abstract: A magnetostrictive waveguide position measuring apparatus includes a waveguide extending between opposed anchored ends. A magnet is displaceable along the waveguide and generates torsional strain in the waveguide in response to an electrical excitation signal transmitted along the waveguide. A piezoelectric film element is coupled to the waveguide to sense the torsional strain signal on the waveguide. A signal processor determines the relative elapsed time between the excitation signal and the output signal of the piezoelectric film element to determine the position of the magnet along the waveguide. The piezoelectric film element is coupled to the waveguide along an axis transverse to the axis of stretch of the element. Alternately, a differential piezoelectric film element formed of two piezoelectric elements contacts a waveguide, with the two elements connected in differential parallel or series configuration and in or out of phase to double the output current or the output voltage. The output of the differential piezoelectric elements are connected to an amplifier in either charge or voltage mode for noise, EMI and transient signal suppression.

Abstract: In a position detection probe having a magnetostrictive wire stretched between a head and a reflective foot end termination, and a magnet displaceable along the probe and using the sonic pulse propagation time from the magnet to the foot as a position detection parameter, compensation for thermal expansion and thermal change of propagation velocity is made based on the property of the total propagation time along the wire length being a unique function of temperature and calibrating the probe at different temperatures to yield either equations or look up tables of true positions as functions of the total propagation time and the position detection parameter. By mapping wire characteristics at a plurality of magnet positions and temperatures to construct look up tables, wire nonlinearities as well as thermal effects can be compensated for.

Abstract: A method and apparatus for determining the position of a movable object along a magnetostrictive wire having first and second opposed ends. A first electrical excitation pulse is applied to a two-wire circuit including the magnetostrictive wire and propagates along the wire to the position of a movable magnet surrounding the wire. The magnet generates oppositely directed first and second torsional waves in the wire. One torsional wave propagates along the wire to a reflective termination at the second end of the wire and is reflected back toward the magnet where it interacts with the magnetic field of the magnet to induce a return electrical pulse in the two-wire circuit. The position of the magnet along the wire is determined from the time differential between the first and second electrical pulses in the two-wire circuit. In another embodiment, a second magnet is mounted in a fixed position about the wire and generates oppositely directed third and fourth torsional waves in response to the first excitation signal, one of which propagates along the wire toward the first magnet which induces an electromagnetic force in the two-wire circuit. A torsional wave generated by the first movable magnet in response to the excitation signal induces another electromotive force in the two-wire circuit when it propagates to the second magnet.

Abstract: A magnetostrictive wire waveguide type position measuring system wherein the wire waveguide is mounted within a small diameter brass tube which, in turn, is mounted by way of resilient suspension components within a rigid outer tube affixed to a position reference frame. The suspension system prevents relatively high frequency shock inputs characteristic of rough environment applications from reaching the waveguide. The position signal is derived from output signal quantities generated by the propagation times of sonic disturbances from a first reference magnet held in a fixed position relative to the outer housing and a second user magnet which moves relative to the outer housing with the element or quantity being monitored. To compensate for longitudinal movement of the waveguide within the floating suspension system and to afford a time interval for further signal compensation purposes, a computer calculates a variable time delay related to the difference between a constant and the propagation time of the reference magnet impulse and adds this variable delay to the user magnet propagation time. Position is determined as a function of the time interval between and original excitation signal and the propagation variably delayed user magnet impulse.

Abstract: In a position detection probe having a magnetostrictive wire stretched between a head and a reflective foot end termination, and a magnet displaceable along the probe and using the sonic pulse propagation time from the magnet to the foot end termination as a position detection parameter, compensation for thermal expansion and thermal change of propagation velocity is made by measuring the wire resistance and calculating a compensation from the resistance. The probe is excited by an electrical pulse having a known current. The voltage across the wire is measured at a time when the current has stabilized to a precise value, and resistance is determined from the current and voltage.

Abstract: A position detection probe having a magnetostrictive wire stretched between a head and a reflective foot end termination, and a magnet movable along the probe uses the sonic pulse propagation time from the magnet to the head as one parameter and the time from the magnet to the foot and reflected back to the head as another parameter for determining the magnet position. The sum of the propagation times is a constant which is used as a reference value. Upon receipt of the first two pulses the propagation times are summed and compared to the reference value, and the data is accepted if the sum is within a prescribed window around the reference value. When noise occurs, it creates a false measure of propagation time so that the sum of the propagation times is no longer equal to the reference value and the data is rejected.
