Description

The Bently Nevada 330878-50-00 is a 3300 XL 50 mm Proximitor Sensor designed for use within vibration monitoring systems. This sensor is a critical component in the 3300 XL series, providing signal conditioning for non-contacting proximity probes. It processes the signal from the probe and extension cable, outputting a voltage proportional to the distance between the probe tip and the observed target, which is essential for monitoring radial vibration, axial position, and speed in rotating machinery.

Features

• Designed for 3300 XL 50 mm proximity probe compatibility.
• System length of 5.0 meters (16.4 feet) for flexible installation.
• Panel mount configuration for secure integration into control cabinets.
• Provides high-accuracy gap measurement for industrial rotating equipment.
• Rugged construction suitable for demanding industrial environments.

Technical Specifications

Installation Guidelines

• Ensure the Proximitor sensor is mounted in a protected, dry location within the control panel.
• Use shielded coaxial cabling for probe connections to minimize electromagnetic interference (EMI).
• Maintain proper grounding practices for the sensor housing to ensure signal integrity.
• Verify that the total system length (probe + extension cable + sensor) matches the calibrated length of 5.0 meters.
• Power down the monitoring system before connecting or disconnecting the sensor to prevent electrical damage.
• Avoid routing signal cables near high-voltage power lines or high-frequency noise sources.

FAQ

What is the primary function of the 330878-50-00?

This unit serves as the signal conditioner for a 3300 XL 50 mm proximity probe system, converting the probe's signal into a usable voltage output for vibration and position monitoring.

Is this sensor compatible with other probe sizes?

No, the 330878-50-00 is specifically designed for the 3300 XL 50 mm probe series and must be used with the corresponding extension cable to maintain system calibration.
