Torsional vibration measurements
Torsional vibration causes oscillatory angular stresses which, added to normal rotational motion, result in drive shaft torsion. That is the reason why the torsional vibration measurements are important in an industrial context.
Torsional vibrations can produce:
- High gear noise
- Faster gears wearing and tearing
- Gear failure
- Slippage of coupling hubs
High values of torsional vibration measurements can therefore have disastrous effects by causing damage to equipment, plant, staff and by generating a negative impact to production.

SINT Technology has developed an integrated telemetric acquisition system for torque and torsional vibration measurements. The software peculiarity is the possibility of carry out time and spectrum analysis and three-dimensional waterfall analysis as well.
In addition to telemetric system for signal transmission, torsional vibration measurements require a bridge arrangement of four strain gauge fitted at 45°. Such a configuration compensates both flexural strenght and temperature variations. The acquired signal, obtained by this kind of torsional vibration measurements, is proportional to the strains that are significant for shear stress and torque estimation.
