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.
Function: Armature mechanism trips on
high vibration and operates snap action switch.
Vibration Range: See How to Select “C”
Frequency Range: 0 to 3600 rpm
Set Point Adjust: 0 to 100% of range. Internal set point adjustment.
Local Reset: For field local reset of the switch
Remote reset with Start-up Delay: Applying reset coil voltage at start up holds mechanism from tripping delay about 3 seconds, after which the switch is automatically activated.
