Product Overview

The 330105-02-12-15-12-05 is a specialized reverse-mount proximity probe within the Bently Nevada 3300 XL 8 mm ecosystem. Engineered for installations where space is a critical constraint or where the probe must be mounted from the opposite side of the machine housing, this model offers high-precision eddy current sensing for vibration and position monitoring. By generating a standard linear scale factor of 7.87 V/mm (200 mV/mil), it provides essential data for protecting rotating assets such as turbines, compressors, and pumps. This reverse-mount configuration is particularly valued for its robust mechanical design and its ability to deliver high-fidelity measurements in confined internal machine environments.

Advanced Technical Features

This reverse-mount probe is built to endure the rigors of industrial monitoring. It features a Polyphenylene Sulfide (PPS) tip that is overmolded onto the internal sensing coil, creating a hermetic barrier against process fluids and moisture. The 330105-02-12-15-12-05 is designed with enhanced RFI/EMI immunity, ensuring signal stability without the need for specialized shielded conduit. Additionally, the ClickLoc connector system provides a gold-plated, vibration-resistant electrical interface, while the integrated connector protector shields the junction from environmental degradation.

System Integration and Benefits

As part of the 3300 XL Transducer System, this probe is fully interchangeable with other XL components, simplifying field maintenance and inventory management.

• Linear Measurement: Offers a standard linear range of 2.0 mm (80 mils), providing superior performance compared to legacy 3000-series transducers.

• Small Target Performance: Optimized for detecting targets in tight spaces with excellent side-view capability.

• Plug-and-Play Compatibility: Can be paired with any 3300 XL Proximitor sensor and extension cable of the matching system length without requiring bench calibration.

• Broad Compatibility: Maintains backward compatibility with previous 3300 series systems, supporting efficient facility upgrades.
