Note this point or mark it with your thumbnail and rotate the meter to read the scale.Ĩ. Turn the gauge sideways to read the exact intersection of the upper edge of the indicator arm with the scale surface.ħ. Read the gauge to judge the preload as follows and as shown in the figure above.Ħ. When you hear or feel a distinct click, please adjust the pressure immediately and lift the gauge carefully so as not to adjust the measured position of the indicator arm.ĥ. Using only one finger, press slowly and firmly on the pressure surface as shown in the figure above (A, B or C). The gauge should be aligned parallel to the belt edges.Ĥ. Make sure that the gauge is in contact with only one belt and that the indicator arm is fully pressed into the scale surface. Place the gauge on one of the drive belts in the center of the belt spine. The figure above (A, B or C) shows three ways to operate the gauge so that pressure is applied to the pressure surface only.ģ. Refer to the procedure instructions below (simplified preload table).Ģ. Select the pretension gauge according to the Profi l and version used. This simplified pretensioning method is designed to make it easier for the fitter to maintain belt drives when the most important technical data is not known and the optimum pretension is not available.ġ. The gauges reliably check whether the V-belt, power band or V-ribbed belt is correctly pretensioned. Sealing and vibration control technology.Propane technology and brazing technology. The tension meter is designed to measure static tension of a belt by determining the natural frequency of vibration of the belt under tension. Generally the ideal pretension level is that which gives least vibration of the unloaded belt span in operation. The value Fpt can be determined by calculation where the peripheral force is known, or empirically where the torque value is unknown. Supplied with long-life 9V alkaline battery, protective leatherette case and transport case with instructions.Frequency range: from 7Hz to 400Hz Accuracy: +/-5%.
