Emerson A6500-UM Universal Measurement Card Datasheet

Product Overview

The Emerson A6500-UM Universal Measurement Card is a versatile component of the AMS 6500 ATG machinery protection system. It’s designed for monitoring various parameters related to machinery health, including:

• Vibration: The A6500-UM can measure both relative shaft vibration and absolute rotor vibration, providing insights into potential bearing or rotor issues.

• Shaft Displacement: This measurement helps detect misalignment, bent shafts, or other mechanical irregularities that can lead to premature wear and tear.

• Rotational Speed: Monitoring rotational speed is crucial for identifying potential overspeed or underspeed conditions, which can cause damage to machinery.

• Proximity: The A6500-UM can measure the proximity of objects to each other, enabling the detection of potential collisions or ensuring proper positioning of mechanical components.

Key Features

• Dual-Channel Operation: The A6500-UM can simultaneously monitor two independent measurement points, doubling the monitoring capabilities within a single module.

• Versatile Input Support: It accommodates various sensor types, including eddy current proximity sensors, differential Emerson sensors, and Hall-effect sensors for rotational speed measurement.

• Diagnostic Capabilities: The A6500-UM offers integrated diagnostic features like Fast Fourier Transform (FFT), PeakVue, and band filters, enabling detailed analysis of vibration data to identify specific fault types.

• Communication Options: The A6500-UM supports multiple communication protocols, including RS-485 and Modbus, for seamless integration into existing control systems and monitoring networks.
