摘要： This invention discloses a type of noncontact linear potentiometer; the potentiometer comprises a slider, a rotating shaft, a guide rod, a tunneling magnetoresistive sensor, a permanent magnet, a printed circuit board, and two support structures. In this configuration the slider moves along the guide rod and the rotating shaft, causing the rotation of the rotating shaft; the permanent magnet is attached to an end of the rotating shaft, and it therefore rotates as the shaft rotates. A tunneling magnetoresistive sensor is located adjacent to the permanent magnet, soldered onto a printed circuit board, and it is used to measure the angle of rotation of the permanent magnet. The guide rod constrains the sliding direction of the slider, and the two support structures are located at the opposite ends of the guide rod and rotating shaft, and they are used to support the rotating shaft and guide rod. Located between the slider and rotating shaft is a ball bearing, a pin and a spring leaf. This potentiometer has several advantages, including a compact structure, easy fabrication, long service life, in addition to providing smooth slider motion that provides a pleasing user experience.

摘要： The present invention discloses a direct read metering device, comprising a digital counting wheel (3) connected with a rotary shaft (5), a micro-controller (7), a ring magnet (2) coaxially installed on the digital counting wheel (3), and a tunneling magnetoresistive angular displacement sensor (1) installed radially displaced from the central axis of the annular magnet (2); the tunneling magneto-resistive angular displacement sensor (1) and the ring magnet (2) are separated by a certain distance in the direction parallel to the central axis of the ring magnet (2); the micro-controller (7) is connected to the tunneling magnetoresistive angular displacement sensor (1) and used to convert the output of the tunneling magnetoresistive angular displacement sensor (1) into a readable number. The device uses the tunneling magneto-resistive angular displacement sensor (1) to sense the angle of a rotary magnetic field generated by the rotation of the ring magnet (2) which is installed on the digital counting wheel (3), in order to permit the code of the digital counting wheel (3) to be determined when the meter is read, thus realizing a direct read metering function. This direct read metering function is applied to provide a direct read water meter.

摘要： The present invention relates to a non-contact potentiometer. The non-contact potentiometer comprises the following parts: a mechanical housing with through-holes; a rotating shaft comprising a top end and a magnet end on which a permanent magnet is fixed and external torque can be applied to the top end, thus driving the rotating shaft and the permanent magnet to rotate around a rotation axis and relative to the housing; a magnetoresistive sensor assembly fixed inside the housing, comprising one or more sensor chips, the sensitivity axis of the sensor chips lies in a sensing plane that is perpendicular to the axis of the rotating shaft, and separated from the permanent magnet by a predetermined distance in the direction parallel to the axis of the rotating shaft, said sensors are used for sensing the magnetic variation produced as the permanent magnet rotates with the rotating shaft thereby generating sensing signals; and three electrical connection terminals, namely a ground terminal, a power terminal, and a signal output terminal. This non-contact potentiometer has the advantages of high precision, low power consumption, and low cost. Additionally, it converts the complex analogue signal from the magnetic sensor into a standard digital format that is easy to use.
