摘要： A fuel sensor includes a cylindrical, one-piece plastic body that has an inlet, an outlet and a fuel passage in between. The body further includes three sensing, thin-walled plate holders that extend from the cylindrical body into and across the fuel passage. Three parallel sensing plates are disposed in the holders for use in forming a pair of parallel plate devices. The thin-walled plate holders surrounding the plates provide isolation of the plates from contact with the fuel. The body also includes a cavity to house a printed circuit board (PCB), which includes signal processing circuitry. The PCB is also isolated from exposure to the fuel. The sensing plates have leads that extend into the cavity for connection to the PCB. An interface connector for connection to an engine controller is also provided. The sensor achieves isolation from exposure to fuel without the use of any coatings.

摘要： A sensing apparatus for determining a property of a fuel such as a gasoline and ethanol blend known as flex fuel includes an acetal plastic tube with an inlet, an outlet and a fuel passage in between. One property of the fuel is a dielectric constant. A pair of sensing plates are placed on opposite sides of the tube leaving the fuel passage unobstructed. A processing circuit on a printed circuit board (PCB) is located near to and is connected with the sensing plates. The circuit applies an excitation signal, senses a capacitance, and generates an output signal indicative of a property of the fuel. The sensed capacitance will increase with increasing concentration of ethanol in the fuel flowing through the passage. A shield for reducing EMI surrounds and encloses the sensing plates and the PCB. An interface connector allows the sensing apparatus to output the capacitance indicative signal to an engine controller or the like.

摘要： A speed sensor (10) includes a sensor housing (12) mounted to the wall of a transmission, and a pole piece (34) extends out of the sensor housing (12) into the transmission fluid. The pole piece (34) is held by a plastic spool (26) within the sensor housing (12), and an electric coil (28) surrounds the spool (26) and is magnetically coupled to the pole piece (34). The spool (26) is formed with a rib ring (41) that extends away from the pole piece (34) and that terminates in an outer periphery that is closely spaced from the inside wall of the sensor housing (12). To block metal particles in the fluid from entering between the spool (26) and sensor housing (12) that would otherwise damage the coil (28), two ribs (60) are formed on the outer periphery of the spool (26), and an interference fit is established between the ribs (60) and the sensor housing (12) such that the ribs (60) are deformed and the contaminants thereby blocked.

摘要： A sensor assembly for sensing the angular position of a rotatable body such as a motor vehicle steering column. The sensor assembly includes a ring gear which is zero calibrated upon assembly of the sensor assembly. The sensor assembly further includes a ring member which functions to lock the ring gear to the sensor housing to maintain the zero calibration between the time of calibration and the subsequent mounting of the sensor assembly on the steering column and further functions to release the ring member for free rotation with the steering column in response to mounting of the sensor assembly on the steering column. The locking and releasing functions of the sensor assembly are performed by a finger structure of the ring member which includes a free end which is engaged in a notch in the sensor housing upon calibration of the sensor assembly to maintain the calibration setting and which further includes a release portion which is engaged by the steering column as the sensor assembly is mounted on the steering column to pivot the finger structure in a sense to move the free end of the finger structure out of the housing notch.

摘要： A vehicle variable reluctance sensor includes a hollow generally cylindrical sensor housing with an open proximal end. Within the interior of the sensor housing is a coil wound around a “T”-shaped spool. The coil is connected to two electrical terminals by two electrical leads. A channel is formed in the spool between the coil and the electrical leads and the electrical leads are disposed within the channel. The channel is flanked on each side by a lip that extends outwardly from the spool. If the electrical leads become slack under extreme temperatures, the configuration of the channel, in conjunction with the lips, prevents the electrical leads from coming out of the channel and unwinding the coil. As such, it is not necessary to tape the coil or otherwise immerse the coil in varnish to prevent the coil from unwinding.
摘要翻译： 车辆可变磁阻传感器包括具有开放近端的中空的大致圆柱形的传感器壳体。 在传感器外壳的内部是卷绕在“T”形卷轴上的线圈。 线圈通过两根电线连接到两个电气端子。 在线圈和电引线之间的线轴中形成通道，并且电引线设置在通道内。 通道在每一侧都由一个从卷轴向外延伸的唇缘。 如果电气引线在极端温度下变得松弛，则通道的配置与唇缘结合可以防止电线从通道中脱出并退绕线圈。 因此，不需要将线圈胶带或以其他方式将线圈浸入清漆中以防止线圈展开。

摘要： A self-retaining transmission sensor includes a sensor housing having a retaining ring extending radially from the sensor housing. When the self-retaining transmission sensor is inserted in a bore in a transmission housing having a diameter slightly smaller than the diameter of the retaining ring, the outer edge of the retaining ring engages the inner wall of the bore and holds the self-retaining transmission sensor firmly in place. Thus, the need for a mounting bracket, a mounting bolt, or a similar device is eliminated.
