Key Features of the Emerson CSI 3120

Dual-Channel Vibration Monitoring

The Emerson A3120/022-000 provides two-channel bearing vibration monitoring for supported industrial machinery. This configuration is suitable for applications requiring vibration measurements at two monitoring points.

Configurable Measurement Settings

Measurement ranges and frequency filtering can be configured according to the connected sensor and application requirements. Alarm settings and available outputs can also be configured through the applicable software.

Analog and Buffered Outputs

The CSI 3120 supports analog current outputs for integration with compatible control and monitoring systems. Buffered voltage outputs are also available for supported measurement and diagnostic applications.

Relay Outputs for Alarm Signaling

The device provides relay outputs that can be used within a compatible machinery monitoring and alarm configuration. Actual alarm and shutdown behavior depends on system settings and the external control circuit.

Industrial Installation

With an IP65 enclosure rating and wall-mounting design, the A3120/022-000 is intended for suitable industrial installation environments. Installation conditions must remain within the manufacturer’s specified electrical and environmental limits.

Technical Specifications

Specifications are based on available Emerson CSI 3120 documentation. Confirm the exact hardware version, connector arrangement, and configuration before purchasing or installing the device.

Typical Applications

The Emerson CSI 3120 bearing vibration monitor is designed for suitable rotating machinery applications, including:

• Steam turbine bearing vibration monitoring
• Gas turbine condition monitoring
• Hydro turbine vibration measurement
• Industrial compressor monitoring
• Pump bearing vibration monitoring
• Industrial fan vibration monitoring
• Machinery maintenance and condition assessment

The correct sensor type and measurement configuration must be selected according to the specific machine and monitoring requirements.

Sensor Compatibility and Installation

The A3120/022-000 is specified for PR9268 series seismic sensors. Before replacing an existing unit, verify the sensor model, connector type, power supply, mounting arrangement, and required output signals.

The device should be installed and configured according to the applicable Emerson manual. Alarm thresholds and relay functions should be checked as part of the commissioning process.

Do not assume that another vibration monitor with a similar model number will be a direct replacement without confirming its electrical and functional compatibility.

Why Verify the Part Number Before Ordering?

Industrial vibration monitoring equipment may have different hardware configurations, connector arrangements, and output options. Confirming the complete order number helps reduce the risk of selecting an incompatible replacement.

When requesting a quotation for the Emerson A3120/022-000, provide the following information:

• Required quantity
• Product condition: new, unused surplus, or used
• Photographs of the nameplate, if available
• Destination country
• Required delivery date

Availability, warranty, and delivery time should be confirmed with the supplier before purchase.
