Description

The Bently Nevada 330850-51-05 is a high-performance 3300 XL 25 mm Proximitor Sensor designed for non-contacting, eddy-current measurement of shaft position and vibration. As a critical component of the 3300 XL 25 mm Transducer System, it provides reliable monitoring for large rotating machinery. This specific model is configured for a 5.0-meter system length and features DIN-rail mounting capabilities for flexible installation in industrial cabinets.

Features

• System Length: 5.0 metres (16.4 feet) for precise signal calibration.
• Mounting: Versatile design supporting DIN-rail or traditional panel mount configurations.
• Advanced Immunity: Enhanced RFI/EMI immunity allows for reliable operation near high-frequency radio signals without requiring special mounting considerations.
• SpringLoc Terminals: Integrated SpringLoc terminal strips facilitate robust, tool-free field wiring connections.
• Backward Compatibility: Compatible with various non-3300 XL series transducer system components.

Applications

• Power Generation: Monitoring steam turbines, generators, and feedwater pumps in thermal, nuclear, and hydropower plants.
• Oil & Gas: Vibration and position monitoring for gas turbines, reciprocating/rotary compressors, and delivery pumps.
• Petrochemical: Essential for heavy equipment such as ethylene plants and ammonia synthesis units.
• Heavy Industry: Suitable for blast furnace fans, large gearboxes, and industrial blowers in metallurgy and steel production.

Technical Specifications

Installation Guidelines

• Handling: Ensure the system is powered down before installing or removing the module from the DIN rail.
• ESD Protection: Handle the sensor and associated cables with standard electrostatic discharge (ESD) precautions.
• Wiring: Utilize the SpringLoc terminals for secure connections. Ensure that the total system length (probe + extension cable) matches the 5.0-meter calibration of this Proximitor sensor.
• EMI/RFI: While the unit features improved immunity, avoid routing signal cables alongside high-voltage power lines or heavy inductive loads.
• Environment: Ensure the installation area is within the specified temperature ratings and protected from direct environmental contaminants.

FAQs

What is the primary function of the 330850-51-05?

It acts as the signal conditioning interface for a 25 mm proximity probe, converting the eddy-current signal into a proportional voltage output for monitoring shaft vibration and position.

Can this sensor be used in older systems?

Yes, the 3300 XL series is designed with backward compatibility in mind, allowing integration with many legacy Bently Nevada transducer system components.

What is the maximum field wiring distance?

While the calibrated system length (probe + extension cable) is 5.0 meters, the field wiring between the Proximitor sensor and the monitoring system can extend up to 305 meters (1000 feet).
