The Bently Nevada 330104-00-05-50-11-00 is a 3300 XL 8 mm Proximity Probe designed for use as a component of the 3300 XL 8 mm Proximity Transducer System. It operates as part of the complete eddy current proximity transducer system together with compatible extension cables and Proximitor® Sensors.

The 3300 XL 8 mm system delivers the advanced performance characteristics of Bently Nevada's eddy current proximity transducer systems. Its system architecture is intended to provide a consistent level of performance across the probe, extension cable, and Proximitor® Sensor when these components are used together.

The standard 3300 XL 8 mm 5-meter system fully complies with the American Petroleum Institute (API) 670 Standard, 4th Edition. This compliance establishes defined requirements for both the mechanical configuration and measurement performance of the complete transducer system.

Frequently Asked Questions

Q : What is product 330104-00-05-50-11-00?
A: This is the 3300 XL series 8mm reverse-mounted eddy current proximity sensor probe manufactured by Bently Nevada, USA.

Q : What does the "8mm" in the probe name refer to?
It refers to the diameter of the probe tip (the plastic-encapsulated sensor head).

Q : What is the linear range of this proximity probe?
The standard linear range is 2.0 mm (80 mils), typically starting from 0.25 mm to 2.25 mm away from the target.

Q : What is the standard scale factor (sensitivity) of this probe?
When paired with a matching 3300 XL Proximitor sensor, the sensitivity is 7.87 V/mm (200 mV/mil).

Q : What length of extension cable should be paired with this 5.0-meter probe?
You must use a 4.0-meter extension cable to complete a standard 9.0-meter system.
