Product Overview

The Bently Nevada 330101-00-15-10-01-00 3300 XL 8 mm Proximity Probe is a high-precision eddy current sensor used in industrial machinery monitoring systems. It is part of the 3300 XL 8 mm proximity transducer system, which is widely used for vibration, shaft position, and machinery condition monitoring in critical rotating equipment.

This probe works together with an extension cable and a Proximitor sensor to provide accurate, non-contact measurement of shaft displacement and vibration in turbines, compressors, pumps, and other rotating machines.

Technical Specifications

Function and Working Principle

The 3300 XL 8 mm proximity probe operates based on eddy current measurement technology.

It works as follows:

• The probe generates a high-frequency electromagnetic field
• When a conductive target (such as a rotating shaft) approaches the probe tip, eddy currents are induced
• The strength of the field changes depending on the distance to the target
• This change is converted into a voltage signal proportional to the gap

$V\propto d$

Where the output voltage changes proportionally with the distance between probe and shaft surface.

This allows the system to measure both:

• Static shaft position
• Dynamic vibration behavior
