Parameter Specifications

• Input Channels: It has multiple input channels, usually 8 to 16 channels, which can receive signals from different types of sensors like proximity probes and accelerometers.
• Signal Range: Accepts input signals in the range of -20 V to +20 V for most applications, with a high input impedance to minimize signal distortion.
• Measurement Accuracy: The displacement measurement accuracy can reach ±0.01 mm, and the vibration velocity measurement accuracy is within ±1%.
• Frequency Range: Can effectively measure signals in the frequency range from 0.1 Hz to 10 kHz, suitable for a wide range of rotating machinery speeds.
• Output: Provides standard 4 - 20 mA analog outputs for process control systems and digital outputs for alarm and trip functions.

Applications

• Machinery Health Monitoring: It is mainly used for continuously monitoring the health condition of rotating machinery in various industries such as power generation, petrochemical and manufacturing.
• Vibration and Displacement Analysis: Monitors vibration amplitude, frequency and displacement of machine shafts to detect potential problems like unbalance, misalignment and bearing faults.
• Condition Assessment: Helps engineers to assess the overall condition of the machinery and make informed decisions about maintenance and repair.

Weight and Dimensions

• Weight: Weighs around 3 - 4 kg, which is manageable for installation and maintenance in industrial settings.
• Dimensions: Typically, it has a length of about 300 mm, a width of 200 mm and a height of 100 mm, designed to fit into standard 19-inch racks or control panels.

Features

• High Integration: Integrates multiple measurement functions in one unit, reducing the need for multiple separate devices.
• Configurable Parameters: Allows users to configure various parameters such as measurement ranges, alarm levels and sampling rates according to specific requirements.
• Data Logging: Has built-in data logging capabilities, which can record historical data for further analysis and troubleshooting.

Stability and Reliability

• Robust Construction: The device is housed in a rugged metal enclosure, providing protection against shock, vibration and environmental factors.
• Power Supply Stability: Equipped with a stable power supply module that can handle voltage fluctuations within a wide range.
• Error Detection and Correction: Incorporates advanced error detection and correction algorithms to ensure the accuracy and integrity of the data.

Actual Cases

• In a Steel Mill: In a steel production plant, the BENTLEY 3500/20-01-02-00 was used to monitor the large rolling mill motors. It detected an abnormal vibration pattern that indicated a bearing problem. Maintenance was carried out promptly, preventing a major breakdown and production disruption.
• In an Oil Refinery: At an oil refinery, it was installed on a centrifugal pump. By continuously monitoring the displacement and vibration of the pump shaft, it helped to optimize the pump operation and detect early signs of wear, extending the service life of the pump and reducing maintenance costs.
