What are different types of balancing machines?

There are two main types of balancing machines, hard-bearing and soft-bearing.

How does a vibration sensor work?

They have a transducer that converts mechanical force caused by vibration or a change in motion, into an electrical current using the piezoelectric effect. High impedance accelerometers produce an electrical charge which is connected directly to the measurement instruments.

What is balancing in vibration?

Balancing is a procedure in which the mass distribution of a rotor is assessed and if necessary, adjusted via addition or subtraction of weight to ensure that the vibration of the journals and/or forces on the bearings are within specified limits.

What is the purpose of balancing machine?

A balancing machine is used to determine the location and amount of unbalanced masses on a rotor. The rotor is mounted on the machine bearings and the machine spins the rotor. Soft bearing machines measure the displacement of the ends of the rotor and bearings.
