The robust, handy FAG Top-Laser TRUMMY2 is an optical-electronic manual measuring instrument belt tension (strand force).

The correct belt tension is an essential prerequisite for achieving the maximum life of the belt drive. In addition, this also gives reduced wear of the drive components, lower energy costs and increased cost-efficiency.

The FAG Top-Laser TRUMMY2 can be used in many locations and comprises a cableless measurement probe, a measurement probe with a cable for difficult to access locations and a microprocessor that displays relevant measurables for belt tension as a frequency (in Hz) or force (in N).

The simple and reliable user menu is given in several languages.

Before measuring the belt tension, the belt mass and length must be entered. Vibration of the belt is then induced. The device measures the natural frequency by means of clock pulse light and uses this to determine the belt tension. This technique is less prone to disruptive influences in comparison with measurement sound waves.
