Series
The 2300/20-00 belongs to the Bently Nevada 2300 series—a line of compact, standalone machinery protection monitors designed for small to medium-sized rotating equipment. The 2300 series is characterized by its simplicity, affordability, and ease of use, offering a range of models with 1–4 channels to suit different application needs. Unlike the modular 3500 series, the 2300 series is optimized for straightforward installations where complex system integration is unnecessary. It maintains Bently Nevada’s reputation for reliability while providing a cost-effective solution for basic machinery protection.
Features
Compact and Space-Saving Design
With dimensions of 96 × 96 × 120 mm, the monitor fits easily into space-constrained control panels or equipment enclosures, making it ideal for retrofitting into existing systems.
Dual-Channel Monitoring
Two independent channels allow simultaneous monitoring of vibration and position on a single machine or two separate pieces of equipment, providing versatile protection in a single unit.
Simple Configuration
Front-panel potentiometers and LED indicators enable quick setup of alarm thresholds and visual status checks, reducing installation time and technical expertise requirements.
Reliable Alarm System
Configurable alarm and danger relays with adjustable time delays ensure timely alerts for critical faults while minimizing false alarms, enhancing operational safety.
Industrial Durability
Robust construction resists vibration, electromagnetic interference (EMI), and temperature fluctuations, ensuring reliable performance in harsh industrial environments.
Function
The primary function of the 2300/20-00 is to monitor vibration and position of small to medium-sized rotating machinery in real time. It converts analog signals from proximity probes into measurable values, processes the data to identify abnormal conditions, and compares measurements against user-defined thresholds. When thresholds are exceeded, it activates relay outputs to trigger alarms (e.g., visual/audio alerts) or safety actions (e.g., equipment shutdowns). The 4–20 mA analog outputs provide continuous data to external systems for remote monitoring and trend analysis.
Use
In industrial settings, the monitor is panel-mounted near the machinery it protects, such as pumps, motors, fans, or small turbines. It connects to proximity probes installed on bearing housings or shafts, continuously tracking vibration levels and shaft position. Operators use front-panel LEDs to check equipment status at a glance, while the analog outputs feed data to centralized control systems for remote monitoring. Maintenance teams use historical data trends to schedule proactive maintenance, reducing unplanned downtime in applications where machinery reliability is critical but complex monitoring systems are unnecessary.
Application Fields
General Manufacturing
In factories and production facilities, it monitors motors, pumps, and conveyor systems, detecting early signs of wear or misalignment to prevent production line disruptions.
Water and Wastewater
It safeguards pumps, blowers, and mixers in treatment plants, ensuring reliable operation of equipment used in water distribution, sewage processing, and filtration systems.
Food and Beverage
In processing facilities, the monitor tracks vibration in mixers, agitators, and packaging machinery, helping maintain production efficiency and compliance with hygiene standards.
HVAC and Building Services
It monitors fans, chillers, and pumps in commercial buildings and industrial HVAC systems, ensuring comfortable indoor environments and reducing energy waste from inefficient equipment.
Renewable Energy
In small-scale wind turbines and solar water pumps, the monitor provides basic protection against vibration-related faults, supporting reliable operation of distributed energy systems.
In summary, the Bently Nevada 2300/20-00 is a practical, reliable solution for protecting small to medium-sized rotating machinery. Its compact design, simple configuration, and essential monitoring capabilities make it an ideal choice for applications where cost and ease of use are balanced with the need to prevent unplanned downtime and equipment damage.
