摘要： A progressive brake lining wear and temperature sensor having a plurality of parallel arranged spaced apart resistors in connection with a sensing circuit. Each resistor is mounted onto a PC board which in turn is encapsulated within a single molding. A thermistor is also mounted onto the PC board within the molding to sense lining temperature. The thermistor is connected to a ground lead. The ground lead, resistance lead and thermistor lead emerge from the encapsulated sensor for connection to the sensing circuit. The sensor is disposed within the brake lining and is connected to the brake shoe by a securement clip. As the brake lining progressively wears, the resistors are progressively worn away thus changing the overall resistance of the sensor. The change in resistance indicates state of wear. Preferably, three resistors are employed to indicate four degrees of brake lining wear.

摘要： A novel arrangement of a capacitive oil level and temperature sensor specifically provided to be mounted to a drive axle housing of a motor vehicle, is disclosed. The sensor comprises an L-shaped hollow body allowing for a simple fit in current production axles. The L-shaped hollow housing of the oil level sensor comprises a pair of mutually perpendicular legs. A substantially vertically oriented first leg includes an oil level detecting capacitor and adapted to be at least partially immersed in an oil reservoir of the axle housing. An oil temperature detecting thermistor is also disposed within the sensor housing. A second leg is substantially horizontally extending from the axle housing and contains an electronic sensor circuitry electrically coupled to the oil level detecting capacitor and to the thermistor, and is adapted to generate oil level and temperature output signals. Furthermore, the second leg of the sensor body is provided with a threaded mounting surface suitable for screwing the sensor into a threaded opening in the drive axle housing and a hexagonal wrench-engaging surface facilitating the installation of the oil level sensor.
