This method requiresonly knowledge of the diameter of the small pulley and thebelt profile. The Optibelt tension gauge is used to directlyread the belt tension. By reducing or increasing the belttension the desired value is achieved.For different tensioning values, optibelt OPTIKrIK 0, I, II, IIIwith corresponding measurement ranges are available. rubber finger loop pressure surfaceindicator arm pocket clip beltpressure springinstructions for use1. The gauge is placed in the middle between the two pulleys on the back of the belt, in the case of sets of belts ideally on the belt in the middle. (Before doing so, please press the indicator completely into the gauge body.)2. Place the gauge loosely on the belt to be measured and slowly press a finger onto the pressure surface.3. Try not to touch the gauge with more than one finger during the measuring process.4. When you feel or hear a definite “click”, immediately release the pressure, the indicator arm stays in the measured position.5. Carefully lift the gauge without moving the indicator arm. read the belt tension (see fig.). read the measurement at the exact point where the top of the indicator arm crosses the scale.6. reduce or increase the belt tension according to the measurement result until it is within the desired tension level. © ArnTz OPTIBELT GrOuP, GErmAny 153

The dimensions are given in the tables 85 to 91 onpages 169/170.By moving to the adjustable pulley the force Q is applied onthe belt. Before measuring the drive centre distance a, thebelt should be rotated three times under load. This ensuresthat the belt is well seated in the pulley, an essentialpre-condition for the accuracy of the resulting measurement.The length is obtained by adding the diameter of the pulleyto twice the drive centre distance a.Ld = 2 a + ud Measuring pulley for wedge beltsLa = 2 a + ua ArpM/MpTALength conversion factors are given in the tables on pages169/170 and 173/174.Arrangement for measuring belt length Measuring pulley for kraftbands Measuring pulley for double-sided V-belts Force Q [n]168 © ArnTz OPTIBELT GrOuP, GErmAny
