Product Overview

The 330101-16-28-10-12-05 is a high-precision 8mm proximity probe representing the advanced engineering of the Bently Nevada 3300 XL series. This non-contacting displacement sensor is designed to provide critical data on shaft vibration and axial position by measuring the gap between the probe tip and a conductive target. Built to survive the most punishing industrial environments, this probe utilizes a patented TipLoc molding process to ensure the sensor head remains structurally bonded to the probe body even under extreme thermal cycling. As a fundamental component of Turbine Supervisory Instrumentation (TSI), it offers deterministic measurements that are essential for the safe operation of high-speed rotating machinery.

Industrial Deployment and Monitoring Applications

This 8mm proximity sensor is a vital asset for monitoring heavy-duty rotating equipment in power plants, oil refineries, and chemical processing facilities. It is specifically optimized for machines utilizing fluid-film bearings, such as centrifugal compressors, steam turbines, and large-scale industrial motors. The 330101-16-28-10-12-05 is expertly used to detect radial shaft vibration, axial thrust position changes, and to provide Keyphasor signals for phase-locked speed measurements. Its rugged armored cable makes it suitable for areas where mechanical abrasion or exposure to lubricants is common. By delivering high-fidelity signals to Bently Nevada 3500 series monitoring racks, this probe facilitates automated machinery protection and advanced predictive maintenance diagnostics.
