Measurement: The belt is tapped in order to make it natural oscillating. 60 mm, whereas darker light and better reflection (can be obtained by attaching a reflective tape) admit a larger measuring distance. Depending upon ambient light and surface of belt, the measurement can occur from a distance of max. The distance to the belt can be 3 – 20 mm.

Preferably, the belt tension should always be measured at the center of the longer belt strand between the two drive pulleys.

With the determined vibration frequency, the belt tension measuring device can often calculate further values for the belt if the necessary initial data have been entered. These vibrations must then be recorded and evaluated at a suitable point with the belt tension meter. To do this, the system must be shut down and the stationary belt set in motion by hitting it. In many applications, the belt tension meter is used to determine the natural frequency of the tensioned belt. Since the belt tension can change during operation of a system due to various influences, it should be checked with a suitable belt tension measuring device during regular maintenance and checks, but also if irregularities occur. But it is not only when installing the belts that you have to pay attention to the correct pretension. The target values for the belt tension are specified by the manufacturer of the system or the belt depending on the area of application, material and construction. A belt tension meter can be used to determine whether an installed drive belt has the recommended pretension.
