EMERSON A6220 Shaft Eccentricity Vibration Monitor

EMERSON A6220  Shaft Eccentricity  Vibration Monitor

DESCRIPTION

The Shaft Eccentricity Monitor is designed for high reliability for the plant’s most critical rotating machinery. This 1-slot monitor is used together with other AMS 6500 monitors to build a complete API 670 machinery protection monitor. Applications include steam, gas, compressors and hydro turbomachinery. The main functionality of the Shaft Eccentricity Monitor is to accurately monitor shaft eccentricity and reliably protect machinery by comparing vibration parameters against alarm setpoints, driving alarms and relays

Product Features

High precision measurement:

A6220 adopts advanced sensing technology and signal processing algorithms to measure shaft eccentricity with high accuracy.

Dual-channel design:

The product has dual-channel inputs, which can monitor the eccentric vibration of two shafts at the same time, improving the efficiency and accuracy of monitoring.

Easy integration:

A6220 has good compatibility and can be easily integrated into existing machinery health monitoring systems for centralised data management and analysis.

Real-time alarm function:

When the eccentric vibration of a shaft exceeds a preset threshold, the A6220 will automatically trigger an alarm to alert the user to deal with potential mechanical failures in a timely manner.

Remote configuration and monitoring:

Supporting remote configuration and monitoring function, users can remotely adjust monitoring parameters and view monitoring data through the network.

Applications

A6220 shaft eccentricity vibration monitor is widely used in various industrial scenarios where shaft eccentricity monitoring is required, such as steam turbines, gas turbines, compressors, generators and other rotating machinery. The A6220 is especially widely used in nuclear power, petrochemical and metallurgical industries.

Technical Specifications

The following are some key technical specification parameters (specific parameters may vary with different models and batches):

Input type: Normally supports electric (electromechanical) sensor inputs.

Number of inputs: Dual channel inputs.

Measurement range: Shaft eccentricity, the exact range can be configured according to actual requirements.

Output types: Common output types include analogue signal outputs such as 0/4-20 mA, 0-10 V, and digital signal outputs (e.g. alarm signals).

Operating Voltage: Typically 220V or other standard industrial voltages.

Working environment: Designed for use in industrial environments with certain anti-vibration, anti-pollution and dust-proof functions.

Product Advantages

Improve equipment reliability:

By monitoring the eccentric vibration of the shaft in real time, potential faults can be detected in time, improving the reliability and stability of the equipment.

Reduce maintenance costs:

Accurate eccentricity measurement helps predict the maintenance cycle and maintenance needs of the equipment, reducing unnecessary maintenance costs and time.

Improve productivity:

Timely detection and treatment of equipment failures to avoid equipment downtime or damage, thereby enhancing productivity.

Use and Maintenance

Installation:

The A6220 should be mounted close to the shaft to be measured to ensure that the sensor can accurately capture the eccentric vibration signal of the shaft.

Calibration:

Before use, the A6220 should be calibrated to ensure the accuracy of the measurement results.

Maintenance:

Regular maintenance checks should be carried out on the A6220, including cleaning the sensor, checking the connecting wires, etc.

Updates:

Pay attention to the manufacturer's update notification to ensure that the latest firmware or software version is being used.
