Core Features & Benefits

→ Dual Independent Monitoring Channels
Simultaneously track vibration on two measurement points per unit, reducing hardware costs and panel space requirements while maintaining independent alarm logic for each channel.

→ Universal Sensor Compatibility
Accepts proximity probes (eddy current), velocity transducers, and accelerometers—eliminating the need for multiple monitor types and simplifying spare parts inventory across your facility.

→ Analog Integration Ready
Provides 4-20mA proportional outputs per channel for seamless connection to DCS, PLC, or SCADA systems, enabling centralized trending, alarming, and historical data logging.

→ Two-Stage Relay Alarming
Configurable Alert and Danger setpoints with independent relay contacts allow progressive response strategies—from operator notification to automatic equipment shutdown.

✓ Field-Adjustable Setpoints
Front-panel potentiometers enable on-site calibration and alarm threshold tuning without specialized software or external tools, reducing commissioning time and maintenance complexity.

✓ Compact DIN Rail Mounting
Space-efficient design fits standard industrial enclosures and control panels, making it ideal for retrofit projects where cabinet real estate is limited.

Application Scenarios

Oil & Gas Production Facilities
Monitor compressor packages, transfer pumps, and blower systems in upstream wellhead operations and midstream processing plants. The 2300/20-CN's wide operating temperature range (-30°C to +65°C) handles outdoor installations and uncontrolled environments where equipment operates continuously.

Chemical & Petrochemical Plants
Protect process pumps, agitators, and centrifuges handling corrosive or hazardous materials. ATEX Zone 2 compliance ensures safe deployment in classified areas, while dual-channel capability reduces monitoring system costs for multi-bearing machines.

Power Generation Stations
Safeguard auxiliary equipment including cooling tower fans, condensate pumps, and feedwater systems. Integration with plant DCS via 4-20mA loops enables coordinated alarming and automated load shedding during abnormal vibration events.

Water & Wastewater Treatment
Track blower packages, clarifier drives, and high-service pumps in municipal and industrial treatment facilities. The monitor's robust construction withstands high-humidity environments and temperature fluctuations common in these applications.

Manufacturing & Material Processing
Monitor conveyor drive systems, air handling units, and process fans in pulp & paper mills, food processing plants, and general manufacturing. Velocity sensor compatibility simplifies monitoring of equipment without dedicated proximity probe installations.

Technical Parameters & Selection Guide

Selection Criteria: Choose the 2300/20-CN when you need cost-effective dual-channel monitoring for equipment where basic vibration trending and two-stage alarming meet your protection requirements. For applications requiring advanced diagnostics, spectral analysis, or digital communication protocols (Modbus, OPC), consider the Bently Nevada 3500 series monitors.

Extended Functions

Buffered Output Option: Some configurations include buffered transducer outputs that allow daisy-chaining to portable analyzers or secondary monitoring systems without signal degradation—enabling periodic detailed diagnostics while maintaining continuous protection.

Sensor Power Supply: Integrated -24VDC proximity probe power supply eliminates the need for external proximitor modules in many installations, reducing system complexity and wiring costs.

Customization Availability: Factory configuration services can pre-set alarm thresholds, sensor types, and output scaling to your specifications, reducing field commissioning time for multi-unit deployments.

Delivery & Service Assurance

Lead Time: Standard units typically ship within 3-5 business days for in-stock items. Custom-configured monitors require 2-3 weeks for factory programming and testing.

Warranty Coverage: 12-month manufacturer warranty covering defects in materials and workmanship. Extended warranty options available for critical applications.

Technical Support: Access to application engineers for sensor selection guidance, wiring assistance, and troubleshooting support via email and phone during business hours.

Documentation Package: Each unit ships with installation manual, wiring diagrams, calibration certificates (when applicable), and quick-start guide. Full technical manuals available for download.

Frequently Asked Questions

Q: What sensor types can I connect to the 2300/20-CN monitor?
A: The monitor accepts three sensor categories: proximity probes (eddy current type, typically 8mm or 11mm), velocity transducers (seismic pickups), and accelerometers (piezoelectric or IEPE type). Sensor type selection is configured via internal DIP switches during installation.

Q: Can I integrate this monitor with my existing PLC or DCS system?
A: Yes, the 4-20mA analog outputs from each channel connect directly to standard analog input modules on PLCs, DCS, or SCADA systems. The output is proportional to vibration amplitude, allowing you to trend data, set software alarms, and log historical values in your control system.

Q: What is the typical installation footprint and panel space requirement?
A: The 2300/20-CN measures approximately 120mm (H) × 100mm (W) × 150mm (D) when DIN rail mounted. Allow additional clearance for wiring access and heat dissipation. One monitor can replace two single-channel units, reducing overall panel space by 40-50%.

Q: Does this monitor provide vibration frequency analysis or FFT capabilities?
A: No, the 2300/20-CN is an overall vibration monitor that measures broadband amplitude (10 Hz to 1 kHz). It does not perform frequency analysis or spectral diagnostics. For fault diagnosis requiring FFT or envelope analysis, consider portable analyzers or the Bently Nevada 3500 series with diagnostic capabilities.

Q: How do I set alarm thresholds for Alert and Danger levels?
A: Alarm setpoints are adjusted using front-panel potentiometers accessible without opening the enclosure. Typical practice is to set Alert at 1.5× normal operating vibration and Danger at 2.5-3× normal levels, though specific values depend on equipment type, speed, and manufacturer recommendations.

Q: Is the 2300/20-CN suitable for hazardous area installations?
A: The monitor carries ATEX Zone 2 certification for installation in control rooms or non-hazardous areas adjacent to classified zones. The monitor itself is not intrinsically safe for Zone 0/1 installation, but it can accept signals from intrinsically safe barriers connected to sensors in hazardous areas.
