Product Overview

The Bently Nevada 2300/20-00 is a dedicated dual-channel vibration monitor engineered to provide cost-effective, continuous machinery protection for essential and general-purpose industrial assets. Positioned as a specialized solution for equipment that does not require a full 3500 rack system, this monitor is a primary choice for managing machine health in power generation, water treatment, and manufacturing sectors. It delivers the same high-integrity signal processing synonymous with the Bently Nevada brand, but in a streamlined, standalone package optimized for individual machine trains or auxiliary casings.

By integrating both vibration sensing and speed measurement, the 2300/20-00 enables synchronous data acquisition, which is vital for accurately identifying phase-related mechanical faults. Its architecture is specifically designed to bridge the gap between simple transmitters and complex rack-based systems, offering professional-grade alarming and trend data for motors, pumps, fans, and small compressors.

Multi-Sensor Compatibility and System Integration

This monitor is highly versatile, supporting two channels of input from a variety of sensor types, including standard accelerometers, Velomitor piezo-velocity transducers, and proximity probes. An additional dedicated speed channel allows for the tracking of rotational velocity, facilitating advanced diagnostics. For protective action, the 2300/20-00 features integrated relay contacts that can be programmed to trigger automated shutdowns or alert sirens when vibration levels cross critical thresholds.

Seamless integration into plant-wide control systems is achieved through configurable 4-20 mA outputs, which transmit real-time trend data to any Distributed Control System (DCS) or PLC. The module’s internal digital signal processing includes programmable bandpass filters (0.2 Hz to 20 kHz), ensuring that the monitor only focuses on the frequency ranges most relevant to specific machinery faults, thereby preventing false trips while maintaining high sensitivity to genuine mechanical degradation.
