Description

Product Overview

The Bently Nevada 330104-01-08-50-01-CN is a precision 8mm reverse-mount proximity probe engineered for critical machinery protection and condition monitoring. This eddy-current sensor provides high-resolution data for shaft vibration, axial position, and speed measurements in heavy industrial rotating assets.

High-Performance Machinery Protection

The 330104-01-08-50-01-CN belongs to the industry-leading 3300 XL series, specifically designed for reverse-mount applications where space or mounting geometry prevents the use of standard forward-mount probes. By utilizing non-contact eddy-current technology, the probe measures the precise gap between the sensor tip and the conductive target material. This configuration enables the monitoring of radial vibration and thrust position on steam turbines, gas turbines, and large centrifugal compressors. Consequently, the sensor provides the essential data required to identify early mechanical faults, such as bearing wear or shaft misalignment, before they escalate into costly failures.

Robust Construction and Signal Integrity

Bently Nevada constructs this probe with a high-grade stainless steel body and a polyphenylene sulfide (PPS) tip to ensure survival in volatile industrial environments. The 330104-01-08-50-01-CN demonstrates exceptional thermal stability, maintaining accurate calibration throughout its wide operating temperature range. Furthermore, the integrated 5.0-meter cable features a sophisticated coaxial design that minimizes signal attenuation and protects against electromagnetic interference (EMI). This shielding ensures that the Proximitor® Sensor receives a clean, high-fidelity signal, even in areas with significant electrical noise or high-frequency vibration.

Versatile Integration and Certification

This probe model carries the CN designation, signifying compliance with specific regional hazardous area certifications for global industrial deployments. It integrates seamlessly into the 3500 Machinery Protection System and other Turbine Supervisory Instrumentation (TSI) platforms. The 3300 XL system provides a linear voltage output proportional to the distance from the probe tip, ensuring compatibility with standard DCS and PLC interfaces. By meeting stringent API 670 requirements, this sensor system offers a reliable, long-term solution for predictive maintenance programs in the petrochemical, power generation, and water treatment sectors.
