    摘要: A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.

    摘要: A sensor unit for a fingerboard latch assembly that comprises a latch bracket and a latch rotatably supported on the latch bracket is mountable on the latch. The sensor unit comprises a sensor configured to sense an adjacent tubular, and a processor that processes the output of the sensor to provide a tubular monitor signal representing the presence or absence of an adjacent tubular A wireless communication unit wirelessly communicates the tubular monitor signal. This allows a wireless sensor unit to be provided that is suitable for operation in remote locations and can verify the presence or absence of tubular to ensure it is securely stored in a fingerboard.

    摘要: A sensor system for sensing the contents of a bore including a plurality of coils disposed behind a non-metallic lining. An oscillator circuit may be used to drive the coils to generate oscillating electromagnetic fields, and a detection circuit generates output signals from each coil representing a parameter of the electrical oscillations that depends on the contents of the bore. The coils may include a primary coil and a one secondary coil, wherein the oscillating electromagnetic field generated by the secondary coil has a lesser degree of interaction with the contents of bore than the oscillating electromagnetic field generated by the primary coil. The sensor system may use the output signal from the secondary coil to compensate the output signal from the primary coil for environmental effects.

    摘要: An elongate component such as a drill string of drill pipes connected by joint sections inside a bore is sensed using at least one set of electromagnetic coils, the coils within the set being arranged at different angular positions around the bore facing the bore. There may be at least two sets of coils separated along the axial direction of the bore. Electrical oscillations are generated in the coils to produce oscillating electromagnetic fields that interact with the contents of the bore. A parameter of the electrical oscillations generated in each coil is detected. The detected parameters may be used to derive both (1) a measure of the axial position along the bore, and (2) a measure of the lateral position. The detected parameters may be used to derive a measure of electromagnetic properties of the contents of the pipe in a region adjacent each coil, thereby imaging the contents of the pipe.
