Cable length measuring devices

Cable length measuring devices are specialised instruments designed to measure the length of cables with precision. They are particularly useful in electrical installations, telecommunications and network cabling.

Cable length measuring devices with a mechanical counter

1. Mechanical design: These devices consist of a frame with a cable guide and a measuring wheel. The measuring wheel is connected to a counter which counts the number of revolutions of the measuring wheel.

2. Counter: The mechanical counter is designed to register every revolution of the measuring wheel. As the measuring wheel has a specific circumference, the counter can calculate the length of cable laid by multiplying the number of revolutions by the circumference of the measuring wheel.

3. Use: To measure the length of a cable, the cable is pulled through the device. During this process, the measuring wheel rotates and the counter counts the revolutions. At the end of the measurement, the user can read the number displayed on the counter to find out the length of the cable that has been unwound.

This type of cable length measuring device is easy to use and does not require an electronic power source. These devices are therefore particularly practical for use in a variety of environments.
