TSM4 Tension Meter
The
TSM4 is a pocket sized belt tension meter which measures the static
tension
of all common toothed, vee, flat and multi-rib belts.
Setting the
correct static tension ( pretension Fpt ) influences the
working life, bearing loads, noise levels and positioning accuracy
of the belt. 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 the least vibration of the unloaded belt span 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.
The natural
frequency is a function of :
- The
static tension (Fpt in N)
- The
span length between two fixed points (L in metres)
- The
belt width in millimetres ( b in mm)
The constant K
specific to each belt type
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 millimeters from the
belt and press the red button.
- The
display will show the frequency of vibration in hertz (Hz).
- 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
