Cable length measuring devices

Cable length measuring devices are used in production or in the construction industry to measure the length of cables, strands, ropes or hoses. The devices are available in versions with a mechanical counter or rotary encoder. The version with a mechanical counter enables mains-independent operation, while the version with a rotary encoder offers greater accuracy.

Cable length measuring devices Structure

The devices consist of a sturdy frame through which the cable is guided. In the lower part of the frame there is a guide roller on which the cable rests. Above the measuring roller is a measuring wheel which rests on the cable. A mechanical counter or encoder is mounted on the side or above the frame, which is connected to the measuring wheel.

Functional principle of cable length measuring devices

To insert the cable, part of the frame is folded upwards. The cable is inserted into the device and the frame is closed again. The cable is now clamped between the guide roller and the measuring wheel. As soon as the cable is pulled through the machine, the measuring wheel rotates. The revolutions of the measuring wheel are thus transmitted to the counter or encoder. If a rotary encoder is installed on the device, the measured values can be transmitted directly to a process controller or a machine controller.
