Overview

The 330103-03-09-10-02-00 serves as an eddy-current proximity transducer within the Bently Nevada 3300 XL family. It measures shaft displacement, radial vibration, and axial position with high accuracy. Therefore, engineers specify it for critical rotating machinery protection. This probe works alongside a matching extension cable and Proximitor sensor. Consequently, the complete system produces a calibrated voltage output proportional to gap distance.

How It Works

The probe tip holds a coil that the driver energizes with a high-frequency signal. This coil generates an alternating magnetic field around the tip. When a conductive shaft target enters the field, eddy currents form on its surface. These currents change the coil impedance, and the driver converts this change into voltage. As a result, the system tracks shaft position without physical contact. Furthermore, the non-contact design eliminates wear and extends service life.

Mounting and Installation

Technicians mount the through a threaded hole in the bearing housing. The 8 mm tip fits standard M10 or 3/8-24 mounting threads. Meanwhile, the ClickLoc connector simplifies cable attachment during installation. Proper target material and surface finish matter greatly for accurate readings. Therefore, installers should verify gap voltage against the calibration curve. Additionally, they must route the cable away from high-temperature zones.
