2300/20_KIT-001-00: Bently Nevada 2300/20 Vibration Monitor Kit
Core Application Value of the 2300/20_KIT-001-00
The Bently Nevada 2300/20_KIT-001-00 solves the challenge of protecting secondary machinery without the high cost of a centralized, multi-slot monitor rack. Specifically, this standalone, high-density vibration monitor provides continuous machinery protection and essential condition monitoring in one compact unit. It eliminates data blind spots on "Balance of Plant" (BOP) equipment such as cooling tower fans, auxiliary pumps, small blowers, and electric motors. These assets often escape detailed monitoring due to budget constraints, yet their sudden failure can halt an entire production line. By installing this complete monitor kit, you establish an authoritative, localized safety interlock that interfaces directly with your PLC or Distributed Control System (DCS).
Technical Specifications & Kit Configuration
The "KIT-001-00" designation specifies a factory-bundled assembly that contains the foundational hardware and terminal blocks required for immediate field mounting.
Monitor Type (2300/20): Dual-Channel Vibration Monitor. The unit accepts up to two independent inputs from proximity probes, velocity sensors, or accelerometers.
Kit Option (001): Standard Internal Configuration. This provides standard processing firmware for monitoring casing vibration or shaft displacement.
Agency Approval Option (00): None / General Purpose. This baseline mechanical package is optimized for non-hazardous, safe-area industrial installations.
Technical Insights & Diagnostic Capabilities
Versatile Sensor Input Channels
The 2300/20 monitor features two fully configurable input channels capable of processing multiple transducer types. You can pair channel one with a 3300 XL proximity probe to track fluid-film bearing wear, while configuring channel two for a 9200 velocity sensor to monitor structural casing shake. Consequently, a single small instrument tracks both relative shaft motion and absolute structural deflection. This dual-sensor versatility saves valuable panel space and provides a comprehensive overview of mechanical asset health.
Integrated 4–20 mA Outputs and Relay Contacts
The module converts raw dynamic sensor signals into steady-state 4–20 mA analog loops and discrete relay actions. It provides independent current loops for each channel, allowing your plant PLC to trend overall vibration levels continuously over time. Furthermore, the hardware includes dedicated "Alert" and "Danger" physical relay contacts to execute automatic machine shutdown commands. Localized hardware processing ensures that emergency trip logic executes reliably within milliseconds, completely independent of network communication status.
Ethernet Connectivity and System 1 Integration
The 2300/20 includes a standard RJ45 Ethernet interface that supports Modbus/TCP and proprietary Bently Nevada communication protocols. This port streams high-resolution trend values and raw diagnostic waveform data straight to your facility network. Therefore, maintenance specialists can connect the unit directly to Bently Nevada System 1 software for advanced spectrum and waveform analysis. Remote diagnostic access enables predictive maintenance modeling without requiring manual site inspections with handheld analyzers.
Field Installation & Maintenance Strategies
DIN Rail Mounting and Thermal Management
Technicians should mount the 2300/20 chassis onto a standard 35mm DIN rail inside a clean, dust-free industrial enclosure. Ensure the cabinet layout provides at least 50 millimeters of clear vertical airflow space above and below the monitor housing. The compact electronic design relies on natural convection cooling to protect internal power components from thermal fatigue over time. Proper thermal management guarantees long-term component stability and prevents unexpected instrument resets in hot field environments.
Shielding Integrity and Proximitor Grounding
Always connect the sensor cable shields tightly to the designated chassis ground terminals on the 2300/20 input block. Do not ground the cable shield at both ends, as this creates ground loop currents that inject electrical noise into your vibration data. Furthermore, verify that the external Proximitor sensor or accelerometer housing remains electrically isolated from the machine frame. Maintaining a single, clean instrumentation ground point eliminates signal distortion and prevents false "Not OK" hardware status alarms.
Buyer’s Guide FAQ
Is the 2300/20 monitor compatible with older 7200 series proximity probes?
Yes, you can configure the input channels via software to accept older 7200 series sensors, standard 3300 XL systems, or generic third-party accelerometers.
What software do I need to configure the 2300/20_KIT-001-00?
The monitor requires Bently Nevada Monitor Configuration Software. You connect your laptop to the monitor's front panel using a standard USB or Ethernet cable to set up your scale factors and relay setpoints.
Does the 2300/20 monitor store historical data if the network goes down?
The unit features internal non-volatile memory that logs a limited history of recent alarm events and trend updates during network communication blackouts.
Can I replace an old 1900/15 monitor with this 2300/20 kit?
Yes, the 2300/20 serves as a modern, network-capable replacement for older standalone monitors like the 1900 series, offering vastly superior diagnostic connectivity.
What is the purpose of the "Bypass" terminal on the input block?
Shorting the bypass terminal temporarily mutes the "Alert" and "Danger" hardware relays. This allows technicians to perform live sensor calibration checks without triggering an accidental plant shutdown.
