Description

 

Discontinued Item:  FOR INFORMATIONAL USE ONLY.  We can recommed the Meggitt Vibro-Meter CVS-100 as a replacement.   Please contact our Sales Team.

The EVS-2 is a 24VDC Electronic Vibration Switch which protects against equipment failure by monitoring velocity-based vibration levels and providing an early warning or shutdown when abnormal vibration is detected. It contains a piezoelectric-crystal internal sensor with built-in microelectronics for reduced noise sensitivity, and adjustable calibrated set-point controls.

The EVS-2 can monitor and alert the operator of abnormal vibration caused by a variety of possible factors, including: imbalance and misalignments, defective sleeve bearings, broken tie down bolts, defective ball or roller bearings, gear mesh, detonation and broken parts, to name a few.

The EVS-2 can be connected to Murphy's TTD™ annunciator, Centurion™ or Millenium™ controllers for increased functionality. It also compliments Murphy's VS2™ shock and excessive vibration/pulsation switch, which is designed to detect vibration due to equipment failure and 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.
