Seiffert Industrial KX-1590 - Sonic Belt Tension Meter

Unlike the force deflection method which involves applying force to the belt, the Seiffert Industrial Sonic Tension Meter measures belt tension by analyzing the harmonic characteristics of a vibrating belt. Belts, like strings, vibrate at a particular natural frequency based on mass and span length. 

The Sonic Tension Meter can easily be operated by one person for fast, accurate readings on all types of synchronous belt drive systems and V-belt drives. Simply enter belt mass constant, belt width and span length into the meter using the built-in keypad. Next, hold the meter sensor just above the belt and lightly strum belt to make it vibrate. Press “measure” button to obtain the reading as a frequency (as hertz) or as a force (pounds or newton's). 

Use the flex sensor to reach inside cramped compartments where conventional measurements would be impossible. The flexible sensor can be bent and repositioned for convenient, one-hand operation.
