Description:

The BENTLY 22810-01-05-50-02​is a Proximitor Power Supply module designed for the Bently Nevada 3500/42M Transient Data Interface.This critical component provides the precise and stable power required for eddy current proximity probes,forming the foundation for reliable vibration and position monitoring in machinery protection systems.

Application Scenarios:

In a large refinery,a critical centrifugal compressor is monitored for radial vibration and axial position using eddy current proximity probes.The BENTLY 22810-01-05-50-02​module is housed within the 3500/42M rack,supplying a clean,regulated-24VDC excitation voltage to these probes.During a sudden thrust bearing failure,the probes detected the rotor’s axial displacement with extreme accuracy.The clean power from the 22810-01-05-50-02​ensured the analog signals from the probes were free of noise,allowing the 3500 system to process the data instantly and initiate a safe shutdown before catastrophic damage occurred.This precise monitoring,powered by a reliable source,prevented a multi-million dollar equipment failure and potential production downtime lasting weeks.

Technical Principles and Innovative Values:

The BENTLY 22810-01-05-50-02​is an integral part of the monitoring system’s signal chain,not just a simple power converter.

Innovation Point 1:Precision Power for Accurate Measurement:​Eddy current probes require an extremely stable and low-noise excitation voltage to produce a highly accurate gap-to-voltage response.The 22810-01-05-50-02​provides this pristine-24VDC supply,ensuring that even micron-level changes in shaft position or vibration are detected without signal degradation caused by power supply ripple or noise.

Innovation Point 2:Integrated System Design:​Unlike a generic external power supply,this module is engineered specifically for the 3500/42M.It is designed to work in harmony with the module’s signal conditioning circuitry,providing optimal filtering and protection.This integration minimizes ground loops and electromagnetic interference(EMI),which are common challenges with external power sources.

Innovation Point 3:High Reliability for Critical Applications:​As a component of a safety-critical machinery protection system,the 22810-01-05-50-02​is built to the highest reliability standards.Its failure would lead to a loss of critical monitoring signals.Therefore,it is designed with robust components and undergoes stringent testing to ensure continuous operation in harsh industrial environments,contributing to the overall high MTBF(Mean Time Between Failures)of the 3500 system.

Application Cases and Industry Value:

A combined-cycle power plant experienced intermittent,unexplained trips on a gas turbine’s vibration monitoring system.Investigation revealed that a faulty aftermarket power supply module,used to replace a genuine BENTLY 22810-01-05-50-02,was introducing electrical noise into the proximitor system.This noise was being misinterpreted by the monitor as high vibration,causing false trips.After replacing it with a genuine 22810-01-05-50-02,the noise was eliminated,and the false trips ceased.The plant avoided an estimated$150,000 in lost generation revenue from just one prevented false trip,demonstrating that the reliability of this power supply directly impacts plant availability and profitability.

Related Product Combination Solutions:

The 22810-01-05-50-02​is a key component within a larger ecosystem for machinery protection.

3500/42M Monitor:​The main module that houses this power supply and processes the vibration/position signals.

Eddy Current Probes(e.g.,3300 XL 8mm):​The sensors that rely on the clean power from the 22810-01-05-50-02.

Proximitors(e.g.,330180-50-00):​The extension cables and connectors that carry the power to the probe and the signal back to the monitor.

3500/15 Power Supply:​Provides the+24VDC system power to the rack,which is then used by the 22810-01-05-50-02.

System 1®Software:​The asset management platform that collects and analyzes data from the 3500/42M monitor,relying on the accuracy of the signal chain powered by this module.

Installation,Maintenance,and Full-Cycle Support:

The BENTLY 22810-01-05-50-02​is not installed as a standalone unit;it is an internal component of the 3500/42M monitor module.Installation involves inserting the fully assembled 3500/42M into a free slot in the 3500 rack.The power supply requires no end-user configuration.

Maintenance is primarily preventative.The health of the entire 3500/42M module,including its internal power supply,is monitored by the 3500 framework and can be reported to a monitoring system like System 1®.If a power supply failure is diagnosed,the standard procedure is to replace the entire 3500/42M module.This modular approach minimizes mean time to repair(MTTR).Our support ensures you receive a fully tested and certified 3500/42M module,guaranteed to contain a genuine and fully functional 22810-01-05-50-02​power supply.We provide a 12-month warranty and technical support for system integration and troubleshooting.
