- BTT-2880S Belt Tension Meter can be used to measure the vibration frequency (unit: Hertz) of the transmission belt when it is hit or moving fast.The tester uses an acoustic probe to capture the sound waves generated by the belt vibrations. After measuring in Hertz, the tester can use this data to calculate the belt tension in newtons.
- Note: Ensure that the correct belt parameters are entered during operation.
Measurement Principle
The calculation and measurement is based on the principle the transverse vibration of the thread" theory. The tester will capture the vibration of the belt, and recordit as a frequency. By entering the mass, width and span length, the relationship between frequency and tension can be found by the following formula:
T=4xMxWxS2 xF2 x10-9
- T: Tension (N)
- M: Unit Mass (g/mm Width * m length)
- W: Belt width or number of ribs (wires) (mm/R)
- S: Measured span length (mm)
- F: Horizontal characteristic frequency (Hz)

Wide Range of Applications
- The handheld Sonic Belt Tension Meter BTT-2880S can test most belt types, including V-belts, cloth-wrapped belts, toothed edge belts, multi-V belts, linkage belts, synchronous belts, and transmission belts. It helps you measure belt tension quickly, reliably, and accurately.
- The handheld Sonic Belt Tension Meter BTT-2880S has a wide range of applications such as heavy duty equipment, fans + pumps, conveyor systems, industrial machines ,compressors, centrifuges, bottling machines, HVAC, truck & bus, steel mill (Cold/Hot), dough mixer, motorcycle, car, bicycle, industrial robot, crusher, printer, vacuum cleaners, washing machines, injection molding machines.
