<p>The invention relates to an arrangement in connection with a central lubrication system, the arrangement comprising a lubricant vessel, a pump unit, a control unit, pipe systems, a pressure monitor unit, at least one lubricant feeder pro-vided with at least one piston (5) which moves due to the influence of the pres-sure of a lubricant present in the pipe system/object to be lubricated, and a movement monitor unit to monitor the operation of the feeder. The invention is characterized in that the movement monitor unit comprises a sensor part (3) mounted to a nipple (4) manufactured from a weakly magnetable material. The nipple (4), in turn, comprises a permanent magnet (2) in order to generate a magnetic field, and a sensor (4) for detecting movement of the piston (5), and an electronics part (13) which processes a signal received from the sensor (4) and produced as a result of a change in the magnetic field caused by the movement of the piston (5) with respect to the sensor part (3), and forwards this processed signal to the control unit.</p> |
