Electronic Vibration Switch (EVS)
The Electronic Vibration Switch (EVS) protects against equipment failure by monitoring velocity-based vibration levels and providing an early warning or shutdown when abnormal vibration is detected.
The EVS product can be connected to Murphy’s TTD™ annunciator, Centurion™ or Millennium™ controllers for
increased functionality.
It also complements Murphy’s VS2™ shock and excessive vibration/pulsation switch, which is designed to detect an abnormal shock or pulsation due to equipment failure and to shutdown other equipment in a system to prevent further damage.
Features:
- Piezoelectric-crystal internal sensor with
built-in microelectronics for reduced noise
sensitivity
• Electronically integrated output signal that measures and trips on velocity
• Adjustable calibrated set-point controls
• Shutdown set-point measured in velocity
• Optional 4-20 mA output for continuous monitoring capability
• Solid-state outputs for setpoint trip
• Adjustable time delay to prevent false tripping on high-vibration start-ups or nonrepetitive transient events
• Self-test and calibration
