Bently Nevada 330103-00-04-50-02-00 8 mm Proximity Probe

The Bently Nevada 330103-00-04-50-02-00 is an 8 mm proximity probe from the 3300 XL 8 mm probe family. It detects the position and movement of a ferromagnetic shaft surface without physical contact, providing a measurement signal for machinery monitoring systems. This configuration features an M10 x 1 metric thread, a 5.0 m total length, and a miniature coaxial ClickLoc connector.

Probe Function and Measurement

The 8 mm proximity probe operates on the eddy-current measurement principle. It senses changes in the distance between the probe tip and a conductive ferromagnetic target. As the shaft moves, the probe detects corresponding changes in the measurement gap and produces a signal for the associated monitoring equipment.

Furthermore, non-contact measurement allows the probe to monitor shaft movement without mechanical contact with the rotating surface. The actual measurement range, sensitivity, and electrical output depend on the complete measurement system configuration.

Mechanical and Connection Configuration

The M10 x 1 metric thread defines the probe's threaded mounting interface. The specified unthreaded length is 0 mm, while the case length is 40 mm. Meanwhile, the 5.0 m total length and miniature coaxial ClickLoc connector are important identification details when checking replacement requirements.

The probe uses standard probe cable construction and has no agency approval option. Therefore, purchasers should check the connector arrangement, cable routing, mounting dimensions, and approval requirements against the existing installation before ordering.

Technical Specifications

Ordering and Configuration Checks

Before replacing an installed probe, compare the complete model number and physical configuration. In addition, verify the companion extension cable and Proximitor sensor requirements against the existing 3300 XL measurement chain. Do not assume that probes with the same nominal 8 mm tip diameter have identical electrical or mechanical configurations.
