● The belt tension meter is an optically measuring maintenance tool for determining the belt tension force. This belt tension meter consists of a display device and a sensor head attached to a semi-flexible gooseneck. The advantage of the gooseneck is that the sensor head can be flexibly positioned. Due to the mobility of the gooseneck, the sensor can measure the strand force even in hard-to-reach places. The belt tension measuring device measures the belt tension (in Newton) and the belt frequency (in Hz) of the belt in the stationary state.
● A small impulse on the belt is sufficient to set the belt vibrating. The belt tension meter measures with the sensor the natural frequency of the belt generated in this way and visualizes it on the display. The belt tension meter can directly determine the actual tension (in Newton / Pound Force) of the belt from the belt frequency combined with the optionally entered belt length and belt mass. However, entering this data is not necessarily required to carry out the measurements directly with the belt tension measuring device. The measurement units in the device can be switched between N (SI unit) and pound force (US unit). The reading is always shown as the belt frequency in Hz on the display of the belt tension measuring device. The intuitive graphic menu is visualized on the high-contrast display of the belt tension measuring device in six different languages. Up to 750 data records can be stored in the memory of the belt tension measuring device. The belt tension measuring device is delivered completely ready for use. The scope of delivery includes the handheld device, the standard sensor with gooseneck, a magnetic holder, batteries, and an operating manual. To increase the flexibility during the measurement, the following items are optionally available to the belt tension meter: an external sensor head with a spiral cable, a device hard case, a frequency mallet, and a tripod.
Applications
● The belt tension measuring device can measure the belt tension of timing belts, ribbed belts, and V-belts. Belt tension is an important parameter for the maintenance, installation, setting up, and repair of the belt drives. The belt tension has to be controlled regularly over the entire running time and adjusted if necessary to ensure the maximum possible service life of all the machine components in the periphery of the belt. The preload force must be selected according to the forces to be transmitted.
● Principally here applies, the greater the forces to be transmitted and the greater the belt speed during operation, the greater the preload forces that must be selected. At the same time, it is necessary to ensure that the belt tension is not set too high, since otherwise the bearings of the belt drives can be affected and, at the same time, the belt-wear increases which may cause belt cracks. At the same time, too low belt tension can also cause damage when, for example, teeth skipping or belt slipping occurs. Because of that, it is important to determine the belt tension or the preload force with a belt tension measuring device. This may help to significantly reduce the follow-up costs occurring due to the unplanned standstill and downtime caused by the bearing damage or by the defective belts. The use of a belt tension measuring device is therefore suitable for applications in the field of industrial production, motor technology, stepper motors, machine and tool construction, or also in the area of maintenance and repair.
