Tension Meter
TSM5 and TSM5-F tension meter
The TSM5 is a pocket size belt tension meter which
measures the static tension of all common toothed, Vee,
flat and multi-rib belts.
Other Belts
Setting the correct static tension (pretension Fpt) influences
the working life, bearing loads, noise levels and positioning
accuracy of the belt.
Specification
•
• CE marked
Frequency range: from 7Hz to 400Hz Accuracy: +/-5%
Supplied with long-life 9V alkaline battery, protective
leatherette case and transport case with instructions
TSM 5
The value Fpt can be determined by calculation where the peripheral force
is known, or empirically where the torque value is unknown. Generally the
ideal pretension level is that which gives least vibration of the unloaded
belt span when in operation.
The tension meter is designed to measure the static tension of a belt, by
determining the natural frequency of vibration of the belt under tension.
Operating instructions
•
• •
On a static drive, gently tap the belt between two
fixed points using a finger or a small screwdriver
Simultaneously hold the sensor head a few millimetres
from the belt and press the red button
The display will show the frequency of vibration in Hertz (H )
To repeat the reading, release the button and repeat the process
It is recommended that several readings are taken to
obtain an average value in order to eliminate possible
errors due to harmonic interference frequencies
