Bently Nevada 330173-00-04-20-12-05 3300 XL 5 mm Proximity Probe

This 5 mm proximity probe delivers precise vibration and position measurements for high-speed rotating equipment. It operates as an essential component within the Bently Nevada 3300 XL transducer system for condition monitoring. The probe uses eddy current technology to generate a voltage signal proportional to the gap between its tip and the conductive target surface. Moreover, it fully complies with API 670 standards for mechanical configuration, linearity, and thermal stability.

Technical Specifications

Design and Installation Benefits

This probe features an M10 x 1 metric thread for mounting in metric-standard machine casings. The 4.0 mm unthreaded length positions the tip precisely for optimal measurement sensitivity. Its 20.0 mm overall case length provides a compact profile for installations with limited clearance. Furthermore, the miniature coaxial ClickLoc connector ensures secure and reliable cable attachment. This design simplifies installation and reduces the risk of connection failures.

Performance and Applications

This probe excels at measuring radial vibration, thrust position, and eccentricity in turbomachinery. It also performs phase reference (Keyphasor) detection for speed and timing measurements. The 3300 XL 5 mm system guarantees complete interchangeability of probes, extension cables, and Proximitor sensors. Consequently, users can replace individual components without recalibration, saving valuable maintenance time.

Environmental Durability

The probe operates reliably across extreme temperatures from -52°C to +177°C. Its PPS tip and stainless steel case resist harsh industrial chemicals, moisture, and abrasive contaminants. The FEP cable insulation maintains excellent flexibility and signal integrity under demanding conditions. Therefore, this probe suits power generation, oil and gas, and heavy industrial applications requiring precise monitoring in confined spaces.
