Wire dispenser SWH

The Draw-wire Dispenser SWH is an accessory. The linear motion of a flexible steel cable, which can have a length of up to 3 m, is converted into a rotary motion using a measuring drum. The measuring drum is connected to a sensor. In this way, a change in displacement of the measuring cable causes the axis of the sensor to rotate by a directly proportional amount that can be recorded. The restoring force of the spring drive keeps the measuring cable stretched at all times and prevents any tipping that would otherwise cause errors. The cable is wound up precisely and reproducibly winding by winding in the roller groove of the drum. The nozzle, through which the cable enters the drum, is protected with a brush and bellows to prevent water or dust from entering the drum.
