330104-00-18-10-01-05 Bently Nevada 3300 XL 8 mm Proximity Probes

Understanding the Technology of the Bently Nevada 330104-00-18-10-01-05

The 330104-00-18-10-01-05 is an 8 mm proximity probe from the respected Bently Nevada 3300 XL series. It uses eddy current technology to perform non-contact measurements. Here’s how it works: the probe generates a high-frequency electromagnetic field at its tip. When a conductive material, such as a metal shaft, enters this field, it induces small electrical currents (known as eddy currents) on the shaft's surface.

As the distance between the proximity probe tip and the shaft changes—due to factors like vibration or a shift in the shaft position—the strength of the eddy currents changes. This, in turn, alters the impedance of the probe's coil. A connected monitor then converts this impedance change into a proportional voltage signal, providing a highly accurate, real-time measurement of the distance between the probe and the shaft. This data is critical for precise vibration monitoring and shaft position analysis.

The model number itself provides a wealth of information about its design:

• 330104: Designates an 8 mm proximity probe for a specific mounting configuration.

• -00: Refers to a 3/8-24 UNF thread, a common standard for installation.

• -18: Indicates the probe's case length, which is 18 inches.

• -10: Specifies the unthreaded length of 1.0 inch, allowing for proper mounting.

• -01: Notes the cable length, which is 1.0 meter.

• -05: Denotes the type of connector, a miniature coaxial connector.

This precise engineering ensures the Bently Nevada 330104-00-18-10-01-05 can be seamlessly integrated into a variety of machinery types, from steam turbines to pumps. Its robust construction allows it to operate reliably in harsh industrial environments, including those with exposure to oil, moisture, and extreme temperatures, making it an ideal tool for continuous condition monitoring.
