Model EURO 366 Vibration Switch

The Model EURO 366 VIBRASWITCH The Model EURO 366 VIBRASWITCH® is primarily intended for indoor and outdoor hazardous and non-hazardous areas in those countries requiring ATEX and CE certifications. The EURO 366 employs the same time proven switch design found in Robertshaw's family of vibration switches.

The Model EURO 366 VIBRASWITCH® is a vibration sensitive device that protects rotating and reciprocating machinery from extensive damage due to mechanical malfunction. When the vibration level of a VIBRASWITCH® protected machine exceeds normal by a preselected amount, the normally open contacts of an internal switch close and the normally closed contacts open. This can be used to actuate either an audible warning system or a shutdown circuit before costly damage occurs Failing bearings, broken blades and similar malfunctions cause increased imbalance or high frequency vibration detectable with the VIBRASWITCH®.

It is designed for maintenance-free service in permanent installations. The VIBRASWITCH® is an acceleration sensitive instrument that measures the total acceleratory shock present on the machine. Acceleration is a vibration characteristic of prime importance in cases of mechanical failure on reciprocating or rotating machinery. Acceleration is directly related to the shock forces (impact) acting on a machine - thus the VIBRASWITCH® offers a valid measurement of the destructive forces acting on the machine. Accelerator measurements made by theVIBRASWITCH® are the summation of all of the individual accelerations giving a total destructive force acting on the machine - the result is positive protection.
