Acoustic measuring device for belt tension

Precise pre-tensioning favours the service life of the belt drive and prevents overloading of the drive components.

Professional belt tension check

Only a perfectly adjusted belt drive can achieve efficient performance. If the belt tension is too high, the bearings are subject to increased wear. If the drive belt tension is too low, the required power cannot be transmitted, the belt can overheat and wear out very quickly.

Accurately measuring and adjusting the belt tension extends the service life of the pulleys, belts, bearings and seals in the long term and prevents vibrations and overloading of the drive.

We generally recommend investing in professional measurement technology, especially when using higher-quality industrial belts. The use of a tensiometer, trummeter or belt tension tester increases the efficiency of the belt drive and reduces wear and energy costs at the same time. The belt tension tester therefore pays for itself within just a few months.

In general, there are various methods of measuring the belt tension of a drive belt:

Force / deflection
Optical vibration measurement
Acoustic vibration measurement

LüCo TensionPro2©

The LüCo TensionPro2© makes it possible to set the appropriate belt tension quickly, easily and precisely. The fully electronic belt tension measuring device is equipped with the latest microprocessor technology and can be used for V-belts, timing belts and power transmission belts. Reliable measurement results are achieved regardless of the type and condition of the drive belt.

The acoustic measuring principle is utilised: A pulse is transmitted to the belt. This initially vibrates in all vibration modes. However, the high-frequency vibrations decay faster than the fundamental vibration. The vibration frequency of the fundamental vibration is in a fixed relationship with the belt pre-tension: the higher the frequency, the higher the belt pre-tension.
