The EVS-2ÿprotects against equipment failure by monitoring velocity-based vibration levels and providing an early warning or shutdown when abnormal vibration is detected.
Features:
? Vibration (0 to 3.0 ips peak)
? Suitable for Universal use - with mounting atÿany angle
? Aluminum Housing
? 4 to 20 mA Analog Vibration Signal

? Rugged Design
The EVS-2 can be connected to Murphy?s TTD? Annunciator, Centurion? or CenturionÿPLUS? controllers for increased functionality. It complements Murphy?s VS2? shock and excessive vibration/pulsation switch designed to detect abnormal shock or pulsation due to equipment failure and to shutdown other equipment in a system to prevent further damage.
The EVS-2 offers two adjustable level detectors with definable response delay for either Warning or Shutdown alarms. Measuring ranges and response times of the level detectors are set by DIP switch. The assigned relay powers a warning or shutdown alarm.
The EVS-2 can be used on any equipment where abnormal vibration could lead to equipment damage, including:
? Cooling Fans
? Engines
? Pumps
? Compressors
? Gear Boxes
? Motors
