Product Overview

In modern industrial machinery protection systems, stable and accurate vibration and displacement measurement is essential for ensuring equipment reliability and operational safety. The Bently Nevada 330780-90-CN 3300 XL 11 mm Front Sensor is designed for high-precision non-contact monitoring of rotating machinery in demanding industrial environments.

As part of the 3300 XL sensor series, this model features a 9.0-meter integrated cable and a region-specific configuration (“CN” variant), making it suitable for system integrations that require standardized regional deployment while maintaining consistent measurement performance.

Technical Specifications

Function and Working Principle

The 330780-90-CN sensor operates using eddy current proximity sensing technology to measure the distance between the probe tip and a conductive target surface without physical contact.

Working principle:

• The probe generates a high-frequency electromagnetic field
• A conductive target modifies the field through induced eddy currents
• The system detects changes in the electromagnetic field strength
• These variations are converted into a proportional electrical signal

This allows highly accurate real-time measurement of shaft vibration and displacement with no mechanical wear.
