Description

Bently Nevada 330172-16-42-10-01-00 3300 XL Extended Temperature Range Proximity Probe

The Bently Nevada 330172-16-42-10-01-00 is a specialized 8 mm proximity probe engineered for displacement and vibration monitoring in extreme thermal environments. As a core component of the 3300 XL ETR Transducer System, this sensor utilizes advanced eddy current technology to track shaft position and radial movement without physical contact. It is designed to bridge the gap between standard monitoring requirements and the high-temperature demands of specialized industrial machinery.

High-Temperature Precision and Technical Architecture

This transducer is specifically configured to maintain signal accuracy in conditions that exceed the limits of standard proximity sensors. Specifically, the 330172-16-42-10-01-00 model features a 1.6-inch threaded case length and a 1.0-meter integral cable, providing a 200 mV/mil (7.87 V/mm) output when integrated into a calibrated 3300 XL system. Furthermore, it is built to provide reliable data for axial displacement and vibration analysis, enabling maintenance teams to observe microscopic changes in shaft behavior under high-load operations.

Technical Specification Matrix

Industrial Utility and Environmental Resilience

The 330172-16-42-10-01-00 is constructed with materials that resist thermal degradation and mechanical fatigue. Moreover, the probe tip and cable assembly are optimized to withstand constant exposure to industrial lubricants and high-pressure steam. In addition, the gold-plated connectors ensure low electrical resistance and prevent signal drift caused by corrosion. Therefore, this transducer is a critical asset for power plants and refineries that require continuous uptime for turbines, gearboxes, and high-speed pumps operating at elevated temperatures.

FAQ

What distinguishes the ETR probe from the standard 3300 XL probe?

The ETR version is specifically rated for significantly higher temperature thresholds at the probe tip and cable. Specifically, while standard probes are robust, the ETR variant uses specialized insulation and potting materials to prevent signal failure in intense heat zones.

Can this 1.0-meter probe be used in a 9-meter system?

Yes, it can be utilized in either a 5-meter or 9-meter configuration depending on the extension cable paired with it. Furthermore, you must ensure the Proximitor sensor is correctly matched to the total electrical length to maintain the 200 mV/mil scale factor.

Is the “01” approval code suitable for my facility?

The 01 code indicates CSA/NRTL/C approval, which is standard for North American industrial installations. Accordingly, it provides the necessary safety certifications for intrinsically safe applications in classified areas within these regions.

How does this probe contribute to predictive maintenance?

By delivering precise, non-contact measurements of shaft position, the sensor identifies early signs of bearing wear or mechanical imbalance.1 Ultimately, this allows operators to schedule repairs during planned outages rather than responding to emergency equipment failures.
