VMRS 200R Series

Product Introduction

The VMS Machine Monitoring System (MMS) VMRS 200R series is 19" Rack Type monitoring system.

It converts a vibration input signal to a user-defined broadband value proportional to RMS of vibration velocity, acceleration or Acceleration Enveloping, True Peak-To-Peak of displacement.

The Alert / Danger relay outputs and 4 to 20mA output signal can directly interface to a Process Control System (DCS or PLC).


  • Mounted in a 19” Rack with single or redundant power supply
  • Up to 32 Dynamic, DC inputs and 8 Digital inputs in each Rack
  • True Simultaneous measurement of all channels
  • With Alert and Danger as two independent set points with LED indication and contact relay outputs for each channel
  • Selectable Individual channel live bar-graph displays
  • Programmable Alert or Danger Level
  • Isolated 4-20mA output signals (Optional)
  • Redundant RS485 Modbus Communication
  • API 670 compliant
