.book Page 12 Wednesday, April 30, 2014 1:39 PM 2 DEVICE DESCRIPTION OPTISYS SLM 2100 Cable drum assembly and heater unit The cable drum helps to move the sensor up and down in the basin. It is mounted directly on the motor shaft of a synchronous motor, hidden behind the drum mounting plate. The cable drum always moves with a very constant speed. Since the diameter of the cable roll in the drum varies, the speed of the sensor varies. That is why the sensor moves slower during the end of the sampling.
