The Clavis hand held beltmeter can be used for all belt tension gauging applications. It produces readings which accurately reflect the tension in the belt, consistently and without operator dependence. This device is in use throughout the world, both as a production tool for accurate belt tension setting, and as a quality control gauge of belt tension. The Clavis belt tension meter is both approved and recommended by most of the major manufacturers of drive belts. The equipment consists of a small sensing head which is held across the belt to be measured. The belt is then tapped to induce the belt to vibrate at its natural frequency. The vibrations are detected and the frequency of vibration is then displayed on the measuring unit. The unit is suitable for measuring tension in all types of power transmission belts, ranging from toothed timing belts, poly-vee belts, and simple vee belts. The frequency measurement range is from 30Hz to 600Hz [Type 4], which covers most automotive applications. A 10-300Hz [Type 3] meter is also available for special applications.

Please note that the Type 4 meter with a frequency range of 30-600Hz now replaces our previous Type 1 meter (range 30-300Hz) and our previous Type 2 meter (30-500Hz).

A general purpose head is supplied, however a range of sensing heads of differing dimensions are available upon request. Rechargeable batteries provide 30 hours of operation. A mains supply charger is supplied. A carrying case is available as an optional extra.
