Overview:
This instrument can be used to measure the vibration frequency
(unit: Hertz) of the transmission belt when it is hit or moving fast.The
tester uses a microphone mounted at the end of the measuring probe
for measurement.After measuring in Hertz, the tester can use this
data to calculate the belt tension in newtons.
NOTE: The operation of the is reliant on the correct belt
informationbeing inputted.Please ensure the correct belt
manufacturers' data is used
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
