Description

Product Overview

The Bently Nevada 330851-06-000-070-50-00-05 is a specialized 3300 XL NSv (Narrow Side View) proximity probe designed for vibration and position measurements in confined industrial spaces. This eddy-current sensor provides high-resolution monitoring for fluid-film bearing machines where standard probe clearances are unavailable.

Precision Vibration and Position Monitoring

The 330851-06-000-070-50-00-05 proximity probe belongs to the 3300 XL NSv series, which specifically addresses applications with restricted side-view clearances. This module utilizes eddy-current technology to measure the distance between the probe tip and the conductive target material, typically a rotating shaft. Because the NSv design reduces the “side-view” effects that often distort signals in tight housings, the probe delivers a highly linear voltage output proportional to the gap. Consequently, maintenance teams can accurately track radial vibration and axial position in small centrifugal compressors, pumps, and other high-speed turbomachinery.

Superior Environmental Resilience

Engineered for the most demanding Turbine Supervisory Instrumentation (TSI) applications, this probe features a robust stainless steel construction that resists chemical corrosion and mechanical wear. The assembly carries an IP65/IP67 rating, which ensures total protection against high-pressure water jets and fine particulate ingress. Furthermore, the 3300 XL series is designed to function across a broad temperature spectrum. This thermal stability allows the sensor to maintain calibration accuracy whether it is exposed to cryogenic environments or intense industrial heat, ensuring that your machinery protection system (MPS) remains active 24/7.

Seamless Integration and Maintenance

The 330851-06-000-070-50-00-05 integrates effortlessly with Bently Nevada’s 3500 and 1900 series monitoring systems through a 3300 XL NSv Proximitor® Sensor. This specific configuration features a 0.5-meter (50 cm) unarmored cable length with a standard 3/8-24 UNF thread, allowing for flexible mounting in various bearing housing profiles. Transitioning to this probe setup simplifies predictive maintenance programs by providing clean, low-noise signals that facilitate early fault detection. By identifying misalignments or bearing wear before they lead to catastrophic failure, this probe significantly extends the service life of critical rotating assets.
