Bently Nevada 2300/20-CN 2300 Series Vibration Monitor

Description

Designed for cost-effective, continuous asset protection, the Bently Nevada 2300/20-CN vibration monitor provides reliable status assessment for critical and general-purpose rotating machinery. This dual-channel monitoring system processes input signals from proximity probes, accelerometers, or velocity transducers to evaluate overall vibration levels, axial position, or rotational speed. Implementing the 2300/20-CN within a facility's predictive maintenance framework enables operators to identify mechanical faults, unbalance, and structural misalignments prior to catastrophic equipment failure. The module features integrated Ethernet capabilities for Modbus TCP/IP communication and supports seamless connection to Bently Nevada's System 1 software for detailed asset condition monitoring and diagnostics.

Features

• Dual-channel dynamic vibration inputs for comprehensive rotating equipment protection.
• Dedicated tachometer input supporting speed measurement and phase reference (Keyphasor) functionality.
• Integrated dry-contact alarm relays for automated machinery shutdown and safety interlocks.
• Proportional 4-20 mA analog outputs for direct PLC or DCS integration.
• Ethernet port supporting Modbus TCP/IP protocol and configuration interface.
• Front-panel LED status indicators displaying power, sensor OK status, and active alarm levels.
• Compact, robust DIN rail mount design suitable for installation in local control panels.

Applications

• Industrial ventilation fans and exhaust blowers.
• Centrifugal, axial, and reciprocating pumps.
• Small steam turbines and auxiliary gas turbines.
• Industrial electric motors and generators.
• Multi-stage gearboxes and cooling tower fans.

Installation Guidelines

• Mounting: Mount the unit securely on standard 35mm DIN rail inside an IP54 or NEMA 4 rated environmental enclosure.
• Shielding: Ensure all sensor input cabling uses shielded twisted-pair wire. Connect cable shields to the monitor's dedicated shield ground terminal. Do not ground the shield at the sensor end.
• Power Supply: Utilize an isolated, regulated 24 VDC power supply with adequate overcurrent protection.
• Ventilation: Maintain at least 50 mm of free clearance space above and below the monitor housing to ensure proper convective cooling.

Compliance and Certifications

• CE Compliant
• UL Listed (US/Canada) for Class I, Division 2 hazardous locations
• RoHS Compliant
