The Bently Nevada 330908-00-30-10-01-CN is an 8mm 3300 NSv proximity probe designed for tight-clearance vibration monitoring. It features a 3.0-inch case, 1.0-meter cable, and ClickLoc connector, providing high-precision data for industrial TSI systems.
The Bently Nevada 330908-00-30-10-01-CN belongs to the 3300 NSv (Nested Square video) series, specifically engineered for applications where structural constraints prevent the use of standard 3300 XL 8mm proximity probes. This probe excels in environments with small target areas or where fluid film bearings require high-precision, non-contact displacement measurements. As a critical component of Turbine Supervisory Instrumentation (TSI), it provides essential data for monitoring radial vibration and axial position, supporting the early detection of mechanical faults in rotating machinery.
The model suffix 330908-00-30-10-01-CN defines the following technical parameters:
The 3300 NSv probe utilizes eddy current technology to measure the distance between the probe tip and the conductive target material (typically the machine shaft). This specific model features a 3/8-24 UNF thread configuration without armor, facilitating a streamlined installation in tight internal machine clearances. The integrated ClickLoc connector ensures a secure, vibration-resistant link to the extension cable, while the included connector protector guards against environmental contaminants.
Because the NSv series handles smaller target sizes than standard probes, it offers superior linearity and a stable scale factor even when measuring narrow shafts or targets with side-view constraints. This reliability ensures 100% OEM performance for predictive maintenance programs, allowing plant operators to monitor asset health without physical contact or wear.
Engineers deploy the 330908 series in high-speed rotating equipment across various sectors, including:
