The common models of Bentley 2300/20 vibration monitoring transmitter are 2300/20-00 and 2300/20-CN. The Bently 233/20 dual-channel monitor conducts online monitoring of the vibration of machinery and issues a high vibration alarm. It has two eddy current sensor or seismic vibration measurement input channels and can receive inputs from various acceleration sensors. One rotational speed input channel, measured synchronously with time; Its outputs include relay contact output, 4-20mA* output, and Modbus TCP output. The Bentley Nevada Monitor Configuration Software (BNMC) can be used to configure the 2300 with extreme convenience.

Main features: Continuous monitoring and protection of applicable equipment; Sturdy and compact integrated equipment The two acceleration input channels are sampled in parallel and synchronized with the rotational speed channel. Two protective relays The outputs of the two protective relays can be programmed and configured according to different set values. A dedicated speed/key phase input channel (eddy current sensor, proximity switch or reluctance speed probe); The vibration measurement values and rotational speed of the local monitor status LED indicator light are displayed locally. The alarm and relay offer convenient and flexible local and remote reset operations. Unified BNMC (Bentley Nevada Monitor Configuration) device configuration and display software; Local and remote configuration locking (two reserved dedicated contacts); Three BNC connector sensors with short-circuit protection and anti-electromagnetic interference buffer outputs including rotational speed signals; 24VDC and optional 240/110V DIN rail mounting power supply module; Network connection using Modbus Ethernet protocol (optional); Overall dimensions: 127x127x76 mm (5x5x3 inches), DIN rail mounting;

The Bentley Nevada 2300/20 series comprises dual-channel vibration monitoring transmitters designed for continuous vibration monitoring and protection of machinery, particularly in less critical or spared applications.These monitors are commonly used across various industries, including:

• Power Generation
• Water Treatment
• Pulp and Paper
• Manufacturing
• Mining
• Cement

Key Features of the 2300/20 Series:

• Dual-Channel Inputs: They accept two channels of seismic or proximity measurement inputs from various accelerometer, Velomitor, and Proximitor types.
• Speed Input: Includes a dedicated speed or Keyphasor channel for time-synchronous measurements.
• Outputs: Features two relay outputs with programmable setpoints for alarming and machinery protection, and a configurable 4-20 mA output for interfacing with a Distributed Control System (DCS).
• Buffered Transducer Outputs: Three buffered outputs (including the speed signal) are available via BNC connectors, providing short circuit and EMI protection.
• Display and Communication: Equipped with an LCD display for showing measurements and speed, LED indicators for status, and Ethernet 10/100 Base-T communication for configuration using Bently Nevada Monitor Configuration software.
• Measurements: Provides real-time key measurements such as direct 0-pk, pk-pk, True RMS, derived pk, and integrated direct pk, with alarm configuration capabilities.
• Robust and Compact: Designed as a self-contained, compact device, suitable for various industrial environments.
• Applications: Ideal for monitoring machine trains or individual casings where the sensor count aligns with the monitor's channels and advanced signal processing is desired.

Bentley 2300/20-00 and 2300/20-CN:

The primary difference between models like 2300/20-00 and 2300/20-CN often lies in their specific configuration or regional certifications.

• 2300/20-00: This typically refers to the base model of the 2300/20 series with standard configurations. The "-00" often indicates a default or "no special options" configuration for certain parameters (e.g., approvals, licenses).
• 2300/20-CN: The "-CN" in the part number often indicates a specific regional certification or configuration, commonly related to compliance with Chinese regulatory standards (e.g., China RoHS, or specific electrical safety requirements for the Chinese market). Functionally, the core vibration monitoring capabilities of the 2300/20-CN would be the same as the 2300/20-00.

In summary, both the 2300/20-00 and 2300/20-CN are dual-channel vibration monitoring transmitters from Bentley Nevada's 2300 series. The difference likely pertains to specific market configurations or certifications, with the "-CN" suffix generally denoting a version configured or certified for the Chinese market.
