With the Conti VSM-3 belt tension gauge, you accurately set the static pretension on timing belts, V-belts, and ribbed belts. Thanks to the non-contact optoelectronic measuring system, you immediately determine the natural frequency of the vibrating belt span, eliminating subjective thumb-pressure estimates while effectively preventing premature belt wear and bearing damage. The flexible sensor arm and compact housing allow you to position the measuring head effortlessly in tight, hard-to-reach machine compartments. You read the measured frequency directly in hertz on the integrated lcd display, ensuring fast, precise, and reliable maintenance or commissioning of industrial drive assemblies.
