TWK draw wire linear transducers are designed for measurements in the range of 1-60 m.
These are devices in which the linear movement of a flexible steel cable is transformed into a rotational motion due to the connection of the wire to the measuring drum. The measuring drum is connected to the encoder shaft. As the wire moves, the encoder records the number of drum revolutions. The tension spring, guaranteeing measurement accuracy, is ensured by a return spring. The wire is always precisely wound and wraps the drum grooves always in the same, repeatable way, eliminating measurement errors. The nozzle, through which the wire enters the drum, is protected against the ingress of water and dust thanks to the brush and the rubber bellows. It is possible to make a wire transducer with an additional lubrication chamber.
