Acoustic belt tension tester BTT-2880S
It can be used to measure the vibration frequency (unit: Hertz) of the transmission belt when it is hit or moving fast.
Features
*Adjustable probe.
* Can store 20 set belt parameters.
* Maximum frequency: 680 Hz.
* Automatic shutdown, etc.
Principle
The calculation and measurement are based on the principle of “transverse vibration of string”.The tester will pick up the vibration of the belt and record it as a frequency.Enter the mass, width, and span
in the following formula.frequency
The relationship between and tension can be calculated in the following formula： T=4xMxWxS2 xF2 x10-9
