Bently Nevada 330709-000-070-10-02-00 Proximity Probe

Overview

The Bently Nevada 330709-000-070-10-02-00 belongs to the 3300 XL series of 11 mm proximity probes. This eddy-current sensor delivers non-contact vibration and displacement measurements for critical rotating machinery. Consequently, engineers deploy it across power generation, oil and gas, and heavy manufacturing environments.

Technical Specifications

The probe features a 70 mm case length and a 1.0-meter cable. Its M16 × 1.5 metric thread ensures secure mounting in standard ports. Additionally, the 11 mm tip diameter provides an extended linear range compared to 8 mm models.

Performance and System Integration

This probe pairs with 3300 XL 11 mm Proximitor sensors and extension cables. Therefore, it integrates seamlessly into existing Bently Nevada monitoring systems. The non-contact eddy current technology maintains accuracy despite oil, dust, and temperature fluctuations.

Moreover, the gold-plated ClickLoc connector ensures low-resistance signal transfer. The 75-ohm triaxial FEP cable resists electrical noise in demanding industrial settings.

Applications

Steam turbines, gas turbines, compressors, and centrifugal pumps commonly use this probe. Maintenance teams rely on it for early detection of bearing wear and shaft instability. Each unit ships factory-sealed with a twelve-month warranty.
