The present disclosure generally relates to a bearing hub assembly of a rail guide wheel apparatus for a rail vehicle. The bearing hub assembly may couple rail wheels to the rail guide wheel apparatus. The rail guide wheel apparatus may be included on a Hi-Rail vehicle or any other vehicle configured to travel along railroad tracks. The bearing hub assembly includes a sensor that is integrally mounted within the bearing hub assembly. The sensor collects information associated with rotation of the rail wheels. Information collected by the sensor may be used to determine a speed, direction, location, and/or distance traveled of the rail vehicle.

According to some embodiments, a load cell for determining a weight of a large object comprises a base plate comprising at least one recessed opening, a bulk metallic glass plug disposed in the at least one recessed opening of the base plate, and a top plate positioned above the base plate. A portion of the top plate is supported by the bulk metallic glass plug. The load cell further comprises a micro strain sensor coupled to the bulk metallic glass plug. The micro strain sensor is operable to determine a change in micro strain on the bulk metallic glass plug. The bulk metallic glass plug extends to a height where the top plate does not contact the base plate.

The present application provides a high-speed train gearbox sensing device, comprising: a housing, disposed on the high-speed train gearbox; a piezoelectric sensor, fixedly disposed in the housing, and with vibration of the high-speed gearbox, converting mechanical energy generated by the vibration into electric energy using piezoelectric effect, and transmitting a signal to a central control system; a shielding case, disposed outside the piezoelectric sensor for shielding electromagnetic interference from the piezoelectric sensor. The above sensing device is installed to the high-speed train gearbox, for collecting vibration information using the piezoelectric sensor, so as to enable monitoring of gearbox vibration. In order to ensure the normal operation of the sensor, the design with high-pressure resistance and anti-electromagnetic interference in structure is adopted to prolong the service life of the sensor, so as to achieve the purpose of real-time online monitoring whether the gearbox is in a good state.
