Belt tension meter (Trummeter) to dertermine the static tension of flat, V and ribbed belts or pretensioned ropes Measuring range: 10 - 800 Hz *The readings can be displayed as frequency (Hz) or strand force (N or lbf) *The belt tension meter includes a display unit as well as a plug in probe for one-hand operation and a probe with cable for limited access space *Measuring principle: red LED light source to determine vibration in Hz * Readings unaffected by nearby magnetic fields or noise *For determinating the spring force in Newton, 2 parameters are needed. Thereby the following restrictions are obtained: - free strand length 9.99 m - belt mass up to 9.999 kg/m * Display menu in several user selectable languages * Manufacturer`s Calibration Report is included
