138708-01 | Bently Nevada | 3500/42M Shaft Absolute I/O Module

Description

The Bently Nevada 138708-01 is an Axial Absolute Input/Output (I/O) module manufactured by Bently Nevada. It is mainly used for the precise monitoring and control of rotating machinery. Here is a detailed introduction about it:

Features Multi-channel Input: It has four input channels and can simultaneously receive signals from up to four absolute shaft encoders. It is capable of synchronously monitoring the positions of multiple shafts, providing a rich data source for a comprehensive understanding of the operating status of rotating machinery. Absolute Positioning Function: Different from incremental encoders that can only track relative changes, this module can provide continuous real-time information on the absolute angular position of the shaft without the need for reference marks. This not only simplifies the installation process but also enables quick and accurate determination of the shaft position during equipment startup and operation, improving the accuracy and reliability of monitoring. High-precision Measurement: It can accurately measure the position and speed of the shaft. The typical accuracy can reach 0.05°, and the speed range is from 0 to 60,000 rpm (depending on the encoder type), providing strong support for the precise control and fault diagnosis of rotating machinery. Robust and Durable: With a robust structural design, it can withstand harsh industrial environments such as high temperature, high pressure, vibration, and impact, ensuring long-term stable operation in various complex industrial scenarios and reducing equipment failures and maintenance costs caused by environmental factors. Easy Installation and Configuration: The module has a simple design, and the installation and configuration processes are straightforward. It can effectively reduce the time for equipment installation and debugging, decrease downtime and maintenance costs, and improve the availability of the equipment. Good System Integration: It is specifically designed to seamlessly integrate with the Bently Nevada 3500 system. It can integrate and analyze the absolute shaft position information with other monitoring data of the 3500 system (such as vibration, temperature, pressure, etc.) to achieve comprehensive health monitoring and fault diagnosis of rotating machinery.

Application Areas Key Machinery Protection: It can monitor the position and speed of the shaft in real-time, promptly detect and prevent mechanical failures such as shaft eccentricity, misalignment, and overspeed, protect key equipment from damage, reduce the risk of production interruptions caused by equipment failures, and ensure the continuity and stability of production. Condition Monitoring: It provides continuous data of shaft parameters. Through the analysis of this data, the performance change trend of the equipment can be predicted, and a maintenance plan can be formulated in advance to achieve condition-based predictive maintenance, optimize the equipment maintenance strategy, extend the service life of the equipment, and reduce maintenance costs. Vibration Monitoring: Integrated with vibration sensors, by combining the position and speed information of the shaft with vibration data, it can provide a more comprehensive insight into the health status of the machinery, helping to detect potential fault hazards such as bearing damage, gear wear, and impeller imbalance at an early stage, and reducing the risk of catastrophic failures.

Technical Specifications Input Channels: 4. Encoder Type: Absolute Shaft Encoder. Signal Type: Digital. Output Signal: Digital pulses representing the position and speed of the shaft. Accuracy: 0.05° (typical). Speed Range: 0 to 60,000 rpm (depending on the encoder type). Operating Temperature: -40°C to 85°C (-40°F to 185°F). Power Requirement: 24 VDC.
