Compact Vibration Monitor with Analog Output Integration

The Bently Nevada 2300/20 represents a breakthrough in standalone vibration monitoring for industrial machinery. Designed for direct PLC and DCS integration, this compact monitor delivers dual 4-20mA analog outputs with internal loop power, eliminating the need for external signal conditioning. Ideal for applications requiring cost-effective machinery protection without the complexity of rack-based systems.

Why Choose the 2300/20 Monitor?

Q: What makes this monitor different from rack-based systems?
A: The 2300/20 offers standalone operation with built-in signal conditioning, reducing installation costs by up to 60% compared to modular rack systems. Its compact 127-127-76mm footprint fits standard control panels while providing enterprise-grade monitoring capabilities.

Q: Can I integrate this directly with my existing PLC?
A: Absolutely. The dual 4-20mA outputs connect directly to standard analog input cards from Allen-Bradley, Siemens, Schneider, or any PLC supporting 4-20mA signals. Internal loop power (0-12Vdc compliance) drives loads up to 600 © without external power supplies.

Q: Is this suitable for hazardous area installations?
A: Yes, when ordered with option code -02, the monitor carries ATEX Zone 2, IECEx, and CSA Class I Division 2 certifications for explosive atmosphere applications in oil & gas, chemical processing, and mining environments.

Application-Specific Solutions

Pump & Motor Monitoring
Deploy on critical water/wastewater pumps, HVAC chillers, and conveyor motors where bearing failures cause costly downtime. Configure one output for overall vibration (0-20mm/s) and the second for bearing condition (0-5g acceleration) to enable predictive maintenance strategies.

Compressor Protection
Protect reciprocating and screw compressors in refrigeration, pneumatic, and process gas applications. The 100ms update rate captures transient events during start/stop cycles, while configurable clamp current (default 2mA) indicates sensor faults to prevent false trips.

Fan & Blower Arrays
Monitor multiple fans in parallel using daisy-chained monitors with individual 4-20mA outputs feeding a central PLC. The compact design allows installation directly on fan housings in space-constrained environments like cooling towers and air handling units.

Gearbox Surveillance
Track slow-speed gearboxes in mining conveyors, cement mills, and sugar crushers where traditional proximity probes are impractical. Pair with accelerometers to detect early-stage gear tooth wear and lubrication degradation.

Integration & Configuration Workflow

Physical Installation: Mount monitor on DIN rail or panel using included hardware. Connect transducer inputs (accelerometer/velocity sensor) to front terminals.
Output Wiring: Run shielded twisted-pair cable from 4-20mA terminals to PLC analog input card. Observe polarity: positive to AI+, negative to AI-.
Software Configuration: Use included configuration software to set measurement ranges, alarm thresholds, and output scaling. USB interface enables laptop connection for setup.
PLC Programming: Scale 4-20mA input (4mA = 0 engineering units, 20mA = full scale). Implement alarm logic based on configured setpoints.
Validation Testing: Verify output linearity using calibration shaker or known vibration source. Confirm alarm activation at configured thresholds.

Ordering Configuration Guide

Part Number Format: 2300/20-AA

Position	Code	Description
A (Approval)	00	Standard (no hazardous area certification)
	02	ATEX/IECEx/CSA explosive atmosphere certifications

Standard Package Includes: Monitor unit, DIN rail mounting adapter, configuration software CD, quick start manual, USB configuration cable.

Important Design Considerations

Loop Power Limitation: The 4-20mA outputs use internal power and will NOT function with externally powered loops. Ensure PLC analog input cards are configured for passive (non-powered) mode.
Cable Specifications: Use 18-22 AWG shielded twisted-pair for output wiring. Maximum cable length: 1000m (3280 ft) with 600 © load.
Grounding: Connect shield drain wire to monitor chassis ground. Do not ground shield at PLC end to avoid ground loops.
Environmental Protection: While rated to 95% humidity non-condensing, install in NEMA 4/IP65 enclosures for outdoor or washdown environments.

Competitive Advantages

vs. Rack Systems	70% lower installed cost, no rack infrastructure required, faster commissioning
vs. Wireless Sensors	Hardwired reliability, no battery maintenance, deterministic update rates
vs. Generic Transmitters	Machinery-specific algorithms, configurable alarm logic, proven Bently Nevada reliability
