Emerson EPRO MMS3120/022-100 Dual Channel Bearing Vibration Transmitter

Application:

• Designed for monitoring and protecting various types of turbo machinery, including fans, compressors, gearboxes, pumps, and other rotational machines.
• Highly flexible with numerous hardware options.
• Can be adapted to specific requirements through versatile combination possibilities.
• Applicable for sensors operating in explosive areas.

Functionality:

• Converts signals from two independent electrodynamic velocity sensors into two separate outputs:
  • Vibration velocity: Proportional to the vibration velocity.
  • Vibration amplitude (peak-to-peak): Proportional to the maximum value of the vibration signals.
• Integrated circuitry includes a self-check function to monitor sensor and transmitter circuit faults.

Technical Features:

• High Precision Measurement:
  • Resolution: Up to 0.01 micrometers.
  • Accuracy: ±0.5 micrometers.
• Wide Measurement Range:
  • Suitable for different industrial applications with a measurement range of up to 100 mm.

Specifications:

• Sensor Inputs:
  • Two independent inputs for seismic vibration sensors (e.g., PR 9268/20, PR 9268/30, PR 9268/60, and PR 9268/70).
• Frequency Ranges:
  • High-pass filter: Selectable at 5/10/15 Hz.
  • Low-pass filter: Adjustable from 50 Hz to 1500 Hz.
• Output Characteristic:
  • Two current outputs (0/4…20 mA) proportional to the chosen characteristic and referenced to the system ground.
• Mounting:
  • Designed to be mounted directly at the machine.
• Redundancy:
  • Two redundant 24 V DC supply inputs.
