PT500 - Mechanical Vibration Switch
Features And Price Comparison Chart
About The Product
The mechanical vibration switch is a low cost solution to provide vibration protection for your rotating or reciprocating machines.
Applications for mechanical vibration switches include cooling towers, motors, fans, fin fans, heat exchangers, engines, reciprocating compressors, centrifuges, rock and coal crushers.
One of the main differences between the PT500 when compared to the competitors is the cost per unit vs features as indicated on the table below.

PT500 Descrption:
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.
This unique design has all industry required environmental and hazardous area approvals. The universal mounting plate mounts in existing mounting holes when replacing older mechanical vibration switches.
Some of the leading products in proximity sensor solutions include PVTVM PT500, Metrix 5550 / 5550G, IMI 685A09 and FW Murphy VS94.
