PT500 Mechanical Vibration Switch


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 set point. 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 set point may be adjusted closer to the vibration levels present during normal operation or running speed of the machine.
