Abstract
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.
Claims18
A sensor assembly for a fingerboard latch assembly, the sensor assembly comprising:
- a mounting arrangement comprising a rigid sensor bracket that is mountable to a pair of bolts on opposite sides of the fingerboard latch assembly;
- and
- plural sensor probes held by the mounting arrangement, the sensor assembly being configured so that, when mounted, the sensor probes are arranged to sense the position of the latch, the sensor probes comprising:
- a closed-position proximity sensor probe that is configured to face downwardly when the sensor assembly is mounted to sense proximity of a crank portion of the latch and/or a piston head in the closed position;
- and
- an open-position proximity sensor probe that is configured to face forwardly when the sensor assembly is mounted to sense proximity of the arm of the latch in the open position.
A combination of:
- a fingerboard latch assembly;
- and
- a sensor assembly comprising:
- a mounting arrangement comprising a rigid sensor bracket that is mountable to a pair of bolts on opposite sides of the fingerboard latch assembly;
- and
- plural sensor probes held by the mounting arrangement, the sensor assembly being configured so that, when mounted, the sensor probes are arranged to sense the position of the latch, the sensor probes comprising:
- a closed-position proximity sensor probe that is configured to face downwardly when the sensor assembly is mounted to sense proximity of a crank portion of the latch and/or a piston head in the closed position;
- and
- an open-position proximity sensor probe that is configured to face forwardly when the sensor assembly is mounted to sense proximity of the arm of the latch in the open position.
