Description

Bently Nevada 330105-02-12-10-02-CN 3300 XL 8 mm Reverse Mount Proximity Probe

The Bently Nevada 330105-02-12-10-02-CN is a specialized 8 mm eddy current proximity sensor featuring a reverse mount design. Part of the globally recognized 3300 XL series, this transducer is specifically engineered for applications where standard probe mounting is restricted. It provides high-resolution, non-contact displacement data, allowing for the precise measurement of vibration and shaft position in critical industrial machinery such as turbines, gearboxes, and centrifugal compressors.

Advanced Sensing and Reverse Mount Engineering

This probe utilizes an eddy current measurement principle to track the distance between the probe tip and a target shaft. Specifically, the reverse mount configuration allows the probe to be installed through the machine casing from the outside, which is essential for certain bearing housing designs. Furthermore, the 3300 XL technology ensures a consistent 3.94 V/mm (200 mV/mil) output when paired with a compatible Proximitor sensor. As a result, the system delivers exceptional linearity and temperature stability, providing reliable diagnostics for early fault detection in high-speed rotating assets.

Technical Specification Matrix

Machinery Protection and Environmental Resilience

Designed to function in the most grueling industrial environments, the 330105-02-12-10-02-CN is fully resistant to moisture, corrosive lubricants, and extreme thermal cycling. Moreover, its robust physical construction minimizes the impact of electromagnetic interference (EMI), ensuring signal clarity near high-power electrical equipment. In addition, the probe integrates directly with the Bently Nevada 3500 series rack, facilitating a comprehensive machinery protection strategy that includes automated alarms and safety trips. Therefore, this sensor is a critical component for reducing unplanned outages and extending the operational life of industrial power-trains.

FAQ

What is the primary advantage of the reverse mount design?

The reverse mount configuration is intended for installations where space inside the machine is limited. Specifically, it allows the sensor to be threaded into the housing from the exterior, making it easier to replace or adjust without fully dismantling the machine’s protective covers.

Can this probe be used with any 3300 series Proximitor?

No, it is specifically designed to work with the 3300 XL 8 mm Proximitor sensor. Furthermore, using it with a non-XL Proximitor or one calibrated for a different probe diameter will result in inaccurate readings. Accordingly, always ensure the entire transducer system (probe, cable, and sensor) is matched.

How does the “CN” approval affect the product’s use?

The “CN” suffix indicates that the probe meets specific regulatory standards for the Chinese industrial market. Consequently, it is the preferred model for projects in that region requiring certified explosion-proof or intrinsic safety documentation for hazardous areas.

Is the probe cable resistant to chemicals?

Yes, the probe features a FEP-insulated coaxial cable. As a result, it offers excellent resistance to most industrial fluids, including turbine oils and synthetic lubricants. Ultimately, this ensures long-term signal integrity even in the presence of aggressive chemical contaminants.
