The Bently Nevada 330905-00-07-10-02-00 is a 3300 NSv metric proximity probe (M10x1) designed for small targets and tight spaces. With a 1.0-meter cable and 70mm case, it provides precision vibration monitoring for centrifugal compressors and high-speed shafts.
The Bently Nevada 330905-00-07-10-02-00 is a high-precision Near Surface (NSv) eddy current proximity probe featuring a metric M10 x 1 mounting thread. This specialized sensor is engineered for machinery with tight installation requirements where standard 5mm or 8mm probes cannot fit, such as centrifugal air compressors and refrigeration units. By utilizing a high-frequency electromagnetic field, the NSv probe successfully monitors radial vibration and axial position on targets as small as 2 mm (0.08 in). Consequently, it allows for high-accuracy diagnostics on small-diameter shafts where curvature or side-view restrictions would otherwise cause signal distortion.
The 330905 probe features a tip made from polyphenylene sulfide (PPS), which provides excellent resistance to the corrosive chemicals and oils commonly found in process gas compressors. Because it is part of the 3300 NSv line, it offers superior “side-view” characteristics, meaning it is less affected by nearby metal surfaces that might otherwise interfere with the sensor’s magnetic field. This makes it the preferred choice for:
Technicians must integrate the 330905-00-07-10-02-00 with a compatible 3300 NSv Extension Cable and 3300 XL NSv Proximitor Sensor to ensure the system maintains its calibrated 200 mV/mil scale factor. Since this probe has a 1.0-meter lead, it is typically paired with a 4.0-meter extension cable to reach the standard 5.0-meter total system length. Furthermore, the ClickLoc connector is designed to be finger-tight, providing a secure, vibration-resistant link that prevents the signal from intermittent grounding—a critical feature for maintaining the integrity of machinery protection data in high-vibration environments.
The Emerson EPRO PR6423/010-000 CON021 Eddy Current Signal Converter delivers ultra-precise, non-contact displacement and vibration measurements for critical rotating machinery. Featuring an tip diameter, a rugged stainless steel housing, and advanced internal temperature compensation, it provides reliable, continuous asset protection and seamless DCS integration in harsh, high-pressure industrial environments.
