Applications:

Belt tension testers test the tension of belts, wires, ropes, tapes, etc, as a means of mechanical strength test. Widely useful in automobile, textile, cables, wires, plastic films, paper, printing, etc. It can be used to measure the tension of auxiliary belts fitted to motor vehicles and other machines.

Measuring Principle:

This has a microphone as a sensor, which measures the vibrating frequency(transverse vibration of a string theory) of the free belt, by converting acoustic sound pressure to electric signals. By measuring the vibrating frequency, tension can be calculated after setting belt parameters of span, width and mass with formula T=4xMxWxS²xF²x10^-9
