Compact Monitors

Measuring and monitoring the vibration level of simple rotating machinery has become economically possible, as PCH Engineering has introduced new cost effective vibration monitors.

The new Compact Range of PCH monitors can be compared to electronic watch-dogs. By permanently monitoring a machine, they reduce the need for human intervention as well as periodic measurements to a minimum.

Price attractive alternative
For users who want to prevent their machines from damaging vibrations, e.g. vibrations coming from unbalance and misalignment.

Bearing Damages
A bearing damage often occurs due to undetected unbalance or misalignment of a machine. Hence the machine runs for a very long time period with a much too high vibration level.

This is the most common reason for serious machine crashes and down time.

Avoid unscheduled production stops
Deciding not to buy a PCH Vibration Guard due to price can be a very unwise decision. Often this leads to extra unexpected expenses to machine repairs, not to mention the further economic loss due to the production stop.
