The Bently Nevada 3500/22M card is part of the 3500 Series Machinery Monitoring System designed for condition monitoring, protection, and diagnostics of critical machinery in industrial environments.

Product Name:

Bently Nevada 3500/22M – Proximitor/Displacement Monitor Card

Product Description:

The Bently Nevada 3500/22M card is an essential module in the 3500 series machinery protection system. It serves as a Proximitor/Displacement Monitor used to measure displacement, gap, or vibration in rotating machinery. The 3500/22M is typically paired with proximity transducers or eddy current sensors to monitor machinery like motors, turbines, compressors, and other critical equipment.

This card features a dual-channel configuration, meaning it can simultaneously monitor two measurement points. It provides continuous data on machine vibration or axial displacement, making it essential for predictive maintenance and real-time monitoring in industrial processes.

The 3500/22M card is designed to work with the Bently Nevada 3500 Series System, which consists of a rack-based architecture where multiple cards (modules) are installed into a central monitor to assess various aspects of machinery health and performance.

Product Parameters:

1. Input Channels:
   • Dual-channel, can monitor two transducers at once.
   • Compatible with proximity probes or eddy current sensors.
2. Measurement Type:
   • Vibration displacement.
   • Axial displacement.
   • Gap monitoring (non-contact).
3. Measurement Range:
   • Typically supports a displacement range from ±0.05 to ±5.0 mm (depending on the sensor used).
4. Signal Output:
   • Provides digital data output that can be used to monitor vibration and displacement trends.
5. Frequency Response:
   • Wide frequency bandwidth to detect both high and low-frequency machinery behavior.
6. Power Supply:

• Signal Processing: Advanced signal processing algorithms for accurate, real-time machinery monitoring and diagnostic capabilities.

Product Use:

The Bently Nevada 3500/22M Proximitor/Displacement Monitor is typically used in critical applications for machinery monitoring, diagnostics, and protection in industries like:

• Power Generation: For monitoring turbines, motors, and other rotating machinery.
• Oil and Gas: Used in compressors, pumps, and turbines to ensure operational safety and efficiency.
• Chemical Plants and Refineries: For monitoring large machinery, preventing costly failures.
• Mining and Metals: To safeguard equipment such as crushers, mills, and conveyors.
• Water and Wastewater: For pumps and motors, ensuring uptime and reducing the risk of unplanned outages.

Common Applications:

• Vibration Monitoring: For detecting early signs of damage or misalignment in rotating machinery.
• Displacement Monitoring: To monitor rotor-to-stator gaps and other critical spacing in rotating equipment.
• Protection: For automatic shutdown in case of excessive vibration or displacement, preventing catastrophic failure.

The 3500/22M is often used in predictive maintenance programs where early detection of faults can help schedule repairs and minimize downtime.
