OTM-1 is a precise instrument for contactless measuring of the belt tension in power transmission drives, like toothed belts or V-belts. The use of OTM-1 enables an optimal function and maximum lifetime of belt drives. The measuring results are reliable, recordable and documentable dates, for calculation-based check of the strand force and bearing load of the belt drive application. The OTM-1 is specially useful for mounting and maintenance. It is also a helpful equipment in the quality assurance and at the final inspection of belt drives.

Product Description: For power transmission belts which can swing freely; not able for transportation belts lying on a slide rail. Non-contact, optical measuring with pulsed light. Measuring at non-running machine, tapping the belt to swing. Exactly measuring of belt frequency and strand force. Exactly calculation of the set points. Needed for protocolling according to DIN EN ISO 9001ff. User guidance and displaying the measuring results in 10 languages: English, German, French, Spain, Portugese, Swedish, Norwegian, Finnish, Danish. Displaying the measuring results on choice as natural belt frequency in Hz or as strand force in Newton or Pound. Easy and save operation. Compact and handy device. Device testing / re-calibrating can be done by the customer with a 250 Hz tuning fork. Versatile use for different materials: All mechanical pre-tensioned parts can be measured, which are able to swing freely, for example belts, robes, wires, films, cables, tapes, and sheets.
