Functional Description

IS220TUBRH2AAA is a vibration monitor board developed by GE. It is a part of Mark VI control system. The Keyphasor Inputs on the system accommodate various types of vibration transducers, including Proximitor, Seismic, Velomiter, and Accelerometers (limited to the first three inputs on PVIB). These inputs play a crucial role in monitoring vibration levels and capturing key operational data for analysis and diagnostics.

Supported Transducers

• Proximitor: Utilized for measuring proximity or displacement, commonly employed in machinery monitoring systems.
• Seismic: Designed to detect ground motion or structural vibrations, often used in seismic monitoring applications.
• Velomiter: Measuring velocity, Velomiter transducers are essential for capturing vibration speed data.
• Accelerometers: Primarily employed in capturing acceleration data, these transducers are crucial for detecting rapid changes in vibration levels.

Configuration for Seismic Transducer

• A negative bias is added to the input to facilitate open circuit detection, enhancing fault identification capabilities.
• The PRxxL signal is opened to enable true differential readings and meet common-mode rejection requirements, minimizing interference and noise.
• The open circuit reading for the gap voltage (DC component) is set to specific values:
• For Proximitor, Accelerometers, and Velomitor inputs, the DC component should read more positive than -1.0 V DC.
• For Seismic inputs, the DC component should read more negative than -15 V DC.

Position and Phasor Inputs

• Similarly, Position Inputs and Phasor Inputs also have specific requirements for their open circuit reading of the gap voltage (DC component), ensuring proper signal integrity:
• The open circuit reading should be more positive than -1.0 V DC for both Position and Phasor Inputs, aligning with system specifications and ensuring accurate measurement capabilities.
• By adhering to these configuration guidelines and signal characteristics, the Keyphasor Inputs facilitate precise vibration monitoring and analysis, enabling effective condition monitoring and predictive maintenance strategies for industrial machinery and systems.
