ABSTRACT:
This invention pertains to a device which is attached on rotating or moving equipment for the purpose of monitoring unsafe levels of equipment vibration. The invention comprises a mechanical assembly which is adjustably sensitive to the vibration amplitude of its given application. The monitor is so designed that it does not include the electronic switching device as an integral part of the invention. Rather, commercially available switching devices (proximity switches) are used as the electronic switching component. In the preferred embodiment, the unit is sensitive to vibration in any plane. The vibration monitor is a signaling device; it can be used to sound an external alarm, engage safety equipment, or disengage or stop moving equipment. It was developed as an inexpensive, rugged, device which can be used in conjunction with general purpose proximity switches to give vibration monitoring capability to an existing proximity switch product line.
