Description of the 330105-02-12-02-05-00

The 3300 series monitors are trusted products tested by countless users worldwide. 

The 3300 system provides continuous online monitoring for machinery protection applications. It is the most powerful and flexible system in our framework-based system, possessing many features and functionalities not found in other systems.

The Bently Nevada 330104-00-20-05-02-00 represents a precision-engineered proximity transducer within the renowned 3300 XL monitoring series, specifically designed for critical vibration and positional measurement in high-speed rotating equipment. Featuring a 5 mm diameter probe tip with PPS (Polyphenylene Sulfide) insulation, the sensor delivers exceptional measurement stability across its full linear range of 0.5-4.5 mm (20-180 mils). The complete assembly incorporates a stainless steel housing with military-grade coaxial connector and a integrated 20-foot (6-meter) cable featuring side-exit configuration for simplified routing in constrained spaces.

Through electromagnetic induction principles, this probe generates a precise gap voltage signal ranging from -1 to -18 VDC, maintaining a calibrated sensitivity of 200 mV/mil (7.87 V/mm) with minimal temperature drift. The robust construction ensures reliable performance in demanding environments, operating continuously at temperatures from -34°C to 177°C (-29°F to 351°F). Engineered for seamless interoperability, the probe directly interfaces with 3300 XL Proximitor® sensors and extension cables, establishing a comprehensive machinery protection system capable of detecting sub-micron level vibrations and early mechanical faults in turbines, compressors, and other critical assets.

10.Mounting Type: Reverse mount design for easy installation in confined spaces.

Importance to the Industrial Control Sector

The Bently Nevada 330105-02-12-02-05-00 plays a critical and often underestimated role in the industrial control sector by extending the reach of predictive maintenance into environments previously deemed too hostile for reliable monitoring.

Its importance is twofold: Asset Protection and Operational Continuity.

By surviving where other sensors fail, the 330105-02-12-02-05-00 provides a continuous stream of high-fidelity data on machine health—such as shaft vibration, axial position, and eccentricity—even in the dirtiest and most physically challenging plants.

This allows control systems to detect emerging faults like imbalance, misalignment, and bearing wear long before they lead to a catastrophic failure.

For industries where a single unplanned shutdown can cost millions of dollars in lost production and repair, the robustness of the 330105-02-12-02-05-00 is not just a convenience; it is a cornerstone of operational and financial risk management.

It empowers a true transition from run-to-failure to predictive maintenance, ensuring that the backbone of heavy industry—its critical rotating assets—can operate safely, efficiently, and reliably.
