Cable length measuring devices

Cable length measuring devices are specialised instruments for accurately measuring the length of cables. They are particularly useful in electrical installation, telecommunications and network cabling.

Cable length measuring devices with mechanical counters

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

2. Counter: The mechanical counter is designed to register each rotation of the measuring wheel. Since the measuring wheel has a specific circumference, the counter can calculate the length of cable travelled by multiplying the number of rotations by the circumference of the measuring wheel.

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

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