2300 Series Vibration Monitor

About The 2300


The 2300 Series Vibration Monitors are designed for use on either a broad range of machine trains or individual casings in which the sensor point count fits the monitor’s channel count.

The 2300 Series vibration monitors are available with proximity sensing to be used on fluid film bearing machines and velometer sensing to monitor slow speed machines. It has been designed to continuously assess and protect essential balance-of-plant equipment assets.

Features and Benefits

Why the 2300 Series?

  • Reliable System that offers improved capability over transmitters for equipment protection.
  • Uses proven to be reliable circuit designs that are also found in the 3300 and 3500 monitoring systems.
  • The 8-channel monitor offers more variety via inputs than other 1900 monitors.
  • Easy installation and configuration with its small size.
  • Flexible mounting options.
  • Flexible dynamic channels that can be configured for vibration, position or speed.

More About the 2300 Series

Product Description

The 2300 Vibration Monitors provide cost-effective continuous vibration
monitoring and protection capabilities for less critical and spared

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 1connectivity for
Trendmaster SPA interface which enables users to leverage existing
DSM SPA infrastructure.


Configuration, Package Options, and Technical Specifications

Many cooling towers are equipped with “earthquake” or “vibration switches” that would drive relay contacts if the structure shakes above a predetermined setpoint and shutdown the unit. These switches react to catastrophic events to prevent further damage, but lack the ability to inform operators of impending failures that could drive predictive maintenance strategy. Cooling tower fans can be challenging to monitor with a portable data collection program as access to the gearbox and/or motor can be restricted under operation, impacting the ability to capture repeatable trend data on emerging issues.

Accelerometers provide the proper frequency range to detect many different failure modes on the gearbox, while providing a low-profile design to accommodate the tight clearances in the cooling towers. The 2300 can integrate acceleration to velocity and provide both condition monitoring capabilities as well as machinery protection in an all-in-one solution.
