A tachometer sensor adapted for measuring the rotation of a gear or spline shaft target within a high pressure environment includes an integrally formed housing having a generally tubular elongate probe defining a sealed interior cavity receiving an annular permanent magnet at the sensing end thereof, field focusing means such as a ferrous pin disposed concentrically with the permanent magnet to shape the field established thereby, at least one magnetoresistive transducer concentrically disposed with the magnet to detect distortions of the magnetic field effected by passage of the target and means in-circuit with the transducer which generates a usable output signals as a function of sensed magnet field distortion.
A proximity sensor adapted for detecting the presence of a target within a sensing region, said sensor comprising:
The proximity sensor of wherein said permanent magnet is radially polarized.
A proximity sensor adapted for detecting target portions of a rotating machine element disposed within a pressurized fluid environment confined by a relatively fixed machine housing, said sensor comprising:
