Bently Nevada 330101-00-32-05-01-05 3300 XL 8mm Proximity Probes

Product Introduction

The Bently Nevada 330101-00-32-05-01-05 3300 XL 8mm Proximity Probe is a precision eddy current sensor engineered for non-contact measurement of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the well-established 3300 XL series, this probe delivers stable electrical output, high sensitivity, and dependable long-term performance under demanding industrial operating conditions.

Designed to operate within a calibrated proximity system, the probe generates a high-frequency electromagnetic field at its tip. When positioned near a conductive shaft surface, variations in the probe gap modify the field characteristics, producing a proportional electrical response. This signal is processed through a compatible Proximitor® sensor and monitoring module to provide accurate real-time vibration and position data.

With a total length of 0.5 meter, this configuration is particularly suitable for installations where compact routing is required or where monitoring modules are positioned close to the measurement point. Its rugged construction and stable electrical characteristics make it ideal for critical equipment such as turbines, compressors, pumps, motors, and generators.

The 330101-00-32-05-01-05 probe plays a vital role in machinery protection systems by enabling early detection of imbalance, misalignment, shaft eccentricity, and mechanical instability.
