Belt Tension Meter “Schmidt” Model RTM-400

Belt Tension Meter RTM-400



Tension range from 10-800 Hz


Belt tension meter (Trummeter) to determine the static tension of flat, V and ribbed belts or pretensioned ropes


Special Features:

§  The readings can be displayed as frequency (Hz) or strand force (N of 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
