Oil port position sensing device

摘要

A portable apparatus for sensing position of an oil port on a rotating element (e.g. the wheel or track of a heavy vehicle) has a position sensor in electrical communication with a wireless transmitter. The wireless transmitter is configured to receive signals from the position sensor and to send signals to a wireless receiver. The apparatus further has a mounting structure (e.g. a magnet) for temporarily mounting the apparatus on the rotating element. An indicium on the apparatus associated with a desired service action to be performed on the rotating element correlates an angular position of the oil port to a pre-determined reference position of the position sensor, the angular position of the oil port being a correct position for performing the desired service action. In use, the apparatus is mounted on the rotating element so that the indicium points at the oil port and then the rotating element is rotated until the receiver indicates that the oil port is in the correct position.

1. A portable apparatus for sensing position of an oil port on a rotating element of a heavy equipment vehicle, the apparatus comprising:
a position sensor that senses angular position of the oil port and in electrical communication with a wireless transmitter, the wireless transmitter configured to receive angular position signals from the position sensor and for sending signals that correspond to the received angular position signals to a wireless receiver that comprises at least one indicator; a mounting structure for temporarily mounting the apparatus on the rotating element; and, an indicium on the apparatus associated with a desired oil service action to be performed on the rotating element, wherein the temporary mounting of the apparatus is chosen at an orientation such that the indicium correlates and indicates an angular position of the oil port with respect to a pre-determined reference angular position reading of the position sensor; wherein the correlation is programmed with respect to the at least one indicator on the wireless receiver to indicate when the angular position of the oil port is being a correct angular position for performing the desired oil service action in response to the wireless receiver receiving an angular position signal corresponding to an angular position of the pre-determined reference angular position reading.
