Tension meter range selection method: usually the maximum tension actually used is 80% of the tensiometer range is the best. The Clavis belt meters are based upon the natural frequency of vibration of the belt. Refer to dimension P in the diagram above. Therefore, when selecting the tensiometer, try to make the diameter of the measured material the same or close to the effective diameter of the tensiometer. The belt is toughed by hand to create vibration. The d and L parameters are fixed in the design of the belt, while the "natural" frequency (f) varies with the applied Belt Tension (T). The sonic tension meter provides the most accurate tension measuring available.Timing belts, like string, vibrate at a particular natural frequency based on mass and span length.By measuring this natural frequency of a free stationary timing belt span the sonic tension meter is able to instantly compute the static timing belt tension based upon the timing belt span length, timing belt width and timing belt type.The sonic tension meter provides accurate and repeatable tension measurements while using a nonintrusive procedure, the measurement process itself doesn't change the belt span tension.Measurement is made by strumming the timing belt like a guitar string to make it vibrate and then hold the meter close to the resonating timing belt to take a measurement. V-belts operate on friction; the friction is multiplied by the mechanical advantage of the wedging principle. Care must be taken to ensure the light is sufficiently reflected by the belt.

If the same drive used a 4-strand 3V PowerBand belt instead of single belts enter "4" for the belt width ("Width" key) . The belt tension meter is an optical measuring instrument for determining the belt tension force. Whenever possible, a Durometer measurement should be taken at least 12 mm (approx. The toothed side of a belt is equally acceptable as a target for the sensor. The BTM-400PLUS picks up the vibration frequency of the Free Belt Span and displays it, or the corresponding belt tension, on the instrument's LCD display panel. To measure the belt mass precisely, we recommend that you weigh the drive belt and then recalculate this weight based on a belt length of 1 meter. Tension meters are available as handheld devices or as equipment for fixed installations. For Belt Type. Lengthen the center distance or adjust the tensioning idler to remove any timing belt slack. If the measured force is greater than the required deflection force, shorten the center distance.
