BENTLY 2300/25 Vibration Monitors

BENTLY 2300/25 Vibration Monitors

Description

The 2300 Vibration Monitors deliver vibration monitoring and high vibration level alarming. They include two channels of seismic or proximity measurement inputs from various accelerometer, Velomitor and Proximitor types, a speed input channel for time-synchronous measurements, and outputs for relay contacts. The 2300/20 monitor features a configurable 4-20 mA output which interfaces more points to a DCS. The 2300/25 monitor features System 1 Classic connectivity for Trendmaster SPA interface which enables users to leverage existing DSM SPA infrastructure.

The 2300 Vibration Monitors are designed for using on a broad range of machine trains or individual casings where the sensor point count fits the monitor’s channel count and where advanced signal processing is desired.

Monitor Key Features

· Trendmaster SPA interface. 

·  Continuous monitoring and protection. 

·  Two Acceleration/Velocity/Proximity inputs with synchronized sampling for advanced diagnostics. 

·  One dedicated speed channel supporting Proximity probes, Magnetic pickup and Proixmity switch type sensor. 

·  Support process variable on all three input channels. 

·  Key measurements (Acceleration pk, Acceleration rms, Velocity pk, Velocity rms, Displacement pp, Displacement rms, Speed) real-time provided with alarm configuration. 

·  Each channel has one measurement group, and can add additional two bandpass measurements and several nX measurements (depends on the device availability). 

·  LCD and LED for real time value and status display. 

· Ethernet 10/100 Base-T communication for configuration using Bently Nevada Monitor Configuration software (included) with RSA encryption. 

·  ocal contacts for positive engagement of monitor bypass, configuration lockout, and latched alarm/relay reset. l Two relay outputs with programmable setpoints. 

·  Three buffered transducer outputs (including Keyphasor signal) providing short circuit and EMI protection. Buffered outputs for each signal are through BNC connectors.
