Abstract
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.
