Emerson A6140 dual-channel shaft absolute vibration monitor

The Emerson A6140 dual-channel absolute shaft vibration monitor is a device used to monitor the absolute vibration of rotating machinery shafts, mainly to ensure the reliable operation of key rotating machinery in factories. The detailed introduction is as follows:

Main Features

Compact Size
It is a dual-channel, 3U-sized, 1-slot plug-in module. Compared with traditional four-channel 6U cards, it can significantly reduce the cabinet space requirement.
Standard Compliance
Complies with API 670 standards and supports hot-swapping, facilitating installation and maintenance.
Diversified Outputs
Equipped with front and rear buffer and proportional outputs, providing multiple output modes such as 0/4-20mA and 0-10V to meet the interface requirements of different devices and systems.
Self-Inspection Function
It can real-time monitor hardware, power input, hardware temperature, sensors, and cables to ensure its normal working status and improve system reliability.

Working Principle

It can connect a displacement sensor and a seismic sensor or piezoelectric sensor. The displacement sensor measures the position and movement of the shaft relative to the casing, while the vibration sensor measures the absolute position of the casing relative to free space. The two sensors perform phase compensation for different units and subtract them through mathematical operations to obtain the absolute displacement of the shaft relative to free space, thereby monitoring the absolute shaft vibration.

Supporting Systems

It is a component of PlantWeb® and AMS software. PlantWeb can provide comprehensive machinery health conditions combined with Ovation® and DeltaV™ process control systems. AMS software provides maintenance personnel with advanced predictive and performance diagnostic tools to accurately identify machine faults at an early stage.

Technical Parameters:

Number of Channels: 2.
Frequency Range: 10Hz to 10kHz.
Measurement Range: Peak velocity 0.01mm/s to 100mm/s; peak acceleration 0.1g to 100g.
Accuracy: ±2% of full scale.
Alarm Output: 4 relays.
Data Recording: Up to 10,000 data points.
Power Supply: 24VDC.
Operating Temperature: -20°C to 70°C.
Dimensions: 160mm×128.4mm×30mm.
Weight: 320g.

Main Application Fields:

Power Industry: It can be used for vibration monitoring of steam turbines and hydraulic turbines. By real-time monitoring the absolute shaft vibration, it promptly detects anomalies in equipment operation, ensures the stable operation of generator sets, reduces downtime caused by vibration faults, and improves power generation efficiency.

Petrochemical Industry: It is commonly used for vibration monitoring of compressors. As a key equipment in petrochemical production, the A6140 effectively monitors the shaft vibration of compressors, prevents equipment damage caused by excessive vibration, ensures the continuity of chemical production processes, and avoids safety accidents (such as material leakage) and production losses due to equipment failures.

Metallurgical Industry: In the metallurgical production process, the A6140 can be applied to vibration monitoring of rotating equipment such as blast furnace fans and driving motors of steelmaking converters. It helps to promptly identify potential problems in equipment operation, ensure the stable progress of metallurgical production, and improve production efficiency and product quality.

Manufacturing Industry: It is suitable for vibration monitoring of various rotating machinery such as motors and gearboxes. Whether in automobile manufacturing, mechanical processing, or other manufacturing fields, it can assess the operation status of equipment by monitoring equipment vibration, provide a basis for equipment maintenance, and reduce equipment maintenance costs and downtime risks.
