The PT 500 is an economical solution to provide basic vibration protection for your rotating or reciprocating machines. The PT 500 uses an inertia sensitive mechanism which actuates internal micro-switch contacts when the vibration level exceeds the adjustable setpoint. The PT 500 start-up delay feature prevents the switch from activating during the higher vibration levels present during the start-up of the machine so that the setpoint may be adjusted closer to the vibration levels present during normal operation or running speed of the machine.

The PT 500 is your “one stop shopping? for all electro-mechanical vibration switch applications. The unique design has all industry required environmental and hazardous area approvals. The E-coat option is suitable for offshore and very corrosive environmental applications. Universal mounting plate will mount in existing mounting holes when replacing older mechanical vibration switches.
