Electronic Vibration Switch Is Designed As Direct Replacement Of Mechanical Vibration Switches.

These Mechanical Switches being used in yester years have very little merit and served the purpose when the requirement was not stringent. As they rely on large impacts or inertia (both acceleration): they do not respond to gradual increase in vibrations. Nuisance tripping during start-up is an usual problem. Further, sensitivity adjustment is too ambiguous to offer any meaningful translation.

For conventional Balancing, the rotating part has to be dismantled from the assembly, taken to the standard Balancing Machine, mounted on cradle, coupled to and driven with a suitable prime mover.

This portable equipment ( Field Dynamic Balancing Equipment ) would enable the operator to carry out balancing without dismantling the machine, by rotating the component in its own frame; thereby saving expensive labour and costly down time. Furthermore, it gives better results than the conventional balancing, as it can detect and correct the residual unbalance due to total assembly, thus accounting for all the fitting tolerances. Balancing at operating speed is another advantage.

This equipment also incorporates a Vibration Meter apart from field Balancing set, which facilitates the absolute measurement of vibration in terms of Displacement in microns or Velocity in mm / sec.
