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 Applications include Fans Cooling Motor Fans Fin Fans Heat Exchangers Engines Reciprocating Compressors Centrifuges SN ANA NS Y A YN ON Rock or Coal Crushers PT500 Features v Wide operating temperature range of 40 C 100 C 40 F 212 F v A All industry environmental ratings v Optional NEMA E coat IP65 environmental rating v Hazardous area agency approvals CSA ATEX CE CE G Ex ERI Universal mounting v Local and remote reset v Start up delay v SPDT 2 SPDT and gold plated contact options Specification 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
