  • Patent number: 11892469
    Abstract: Apparatus and associated methods relate to monitoring health of a system for sensing rotational frequency of a rotatable member. A plurality of magnetic speed probes, each of which is configured to sense the rotational frequency of the rotatable member, are arranged in transmissive proximity with one another. A transmitter-configured one of the plurality of magnetic speed probes includes a signal coupler that couples an electrical signal generated by a radio-frequency signal generator into the inductive coil of the transmitter-configured magnetic speed probe, thereby radiatively transmitting an electromagnetic signal. A speed-probe monitor electrically coupled to each of the plurality of magnetic speed probes determines, based on the coil current sensed by each of the plurality of magnetic speed probes in response to the electromagnetic signal radiatively transmitted, health of the system.

  • Patent number: 11549390
    Abstract: Apparatus and associated methods relate to health-monitoring of a magnetic speed probe. An inductive coil of the magnetic speed probe is used for two purposes: i) to sense a changing magnetic field caused by rotation of a rotating member; and ii) to radiatively transmit radio-frequency signals for determining the health of the magnetic speed probe. A signal generator coupled to the inductive coil of the magnetic speed probe generates the radio-frequency signals that, when conducted by the inductive coil, causes an inductive coil to act as a radio transmitter by radiatively transmitting the radio-frequency signals. The radio-frequency signals transmitted by the inductive coil are detected by a radio receiver. The radio-frequency signals received are indicative of health of the magnetic speed probe.

  • Publication number: 20220252631
    Abstract: Apparatus and associated methods relate to optically determining rotation frequency of a rotatable member using a Fabry-Perot cavity formed between a mirror and a movable reflective mirror. A cavity dimension between the mirror and a movable reflective mirror changes in response to movement of the movable reflective mirror. The movable reflective mirror is bonded to a magneto-strictive material having a thickness dimension that changes in response to changes in a magnetic field. A magnet generates the magnetic field, which changes in response to rotation of the rotatable member.

  • Patent number: 10996114
    Abstract: Apparatus and associated methods relate to measuring temperature of a fluid within a hydraulic vessel using a temperature probe that has an annular recess circumscribing a projecting sensor tip. The annular recess is configured to permit fluid flow into an aperture region of a vessel wall through which the temperature probe contacts the fluid within the hydraulic vessel. Because the temperature probe projects from the annular recess within the aperture, a net projection dimension, as measured in a projection direction from an interior surface of the vessel wall proximate the aperture to a sensor, is less than a gross projection dimension, as measured in the projection direction from a bottom of the annular recess to the sensor tip. In some embodiments, this configuration advantageously improves a ratio of thermal conductivity between the fluid and the temperature probe and thermal conductivity between the temperature probe and a sensor housing.
