Product Overview

The 330104-02-08-10-01-00 is a high-precision eddy current proximity transducer from Bently Nevada’s flagship 3300 XL series. This 8 mm probe is engineered for non-contacting displacement measurements, providing vital data for vibration monitoring, axial thrust position, and eccentricity in critical rotating machinery. Featuring a metric M10 x 1 threaded body and integrated stainless steel armor, this specific configuration is built for high-durability applications where the cable requires protection from mechanical abrasion or fluid exposure. As a cornerstone of Turbine Supervisory Instrumentation (TSI), it offers a linear voltage output proportional to the gap between the probe tip and the target material.

Technical Configuration

The model number 330104-02-08-10-01-00 corresponds to the following physical and mechanical specifications:

• Thread Pitch: M10 x 1

• Protection: Flexible stainless steel armor (FEP coated lead)

• Net Weight: 0.06 kg

Robust Design and Engineering

The 330104-02-08-10-01-00 is constructed with a high-performance Polyphenylene Sulfide (PPS) tip, which is overmolded onto the sensing coil to create a hermetic seal against oil, water, and steam. This design ensures signal stability in temperatures ranging from -51 °C to +177 °C. The proprietary ClickLoc connector system provides a gold-plated, vibration-resistant connection, eliminating the risk of accidental disconnection during high-speed machinery operation. The system is factory-calibrated for AISI 4140 steel, maintaining a standard scale factor of 7.87 V/mm (200 mV/mil).

System Integration and Applications

A primary advantage of the 3300 XL 8 mm system is the total interchangeability of its components. Probes, extension cables, and Proximitor sensors of the same system length can be mixed and matched without the need for manual bench calibration.

• Machinery Protection: Essential for monitoring radial vibration in fluid-film bearing machines such as gas and steam turbines.

• Position Sensing: Ideal for axial thrust measurements to prevent rotor-to-stator contact.

• Hazardous Environments: Fully certified for use in explosive atmospheres globally.

• Backward Compatibility: Electrically compatible with legacy 3300 series 5 mm and 8 mm components, facilitating easy system upgrades.
