Description：

The Bently Nevada 330103-00-16-50-12-05 is a 3300 XL 8 mm Proximity Probe designed for continuous shaft condition monitoring in high-value rotating machinery. As a key component of the 3300 XL 8 mm Proximity Transducer System, it works with a compatible extension cable and Proximitor Sensor to deliver precise, non-contact measurements used for machinery protection and predictive maintenance.

Based on eddy current sensing technology, the 330103-00-16-50-12-05 generates an output voltage that varies in direct proportion to the distance between the probe tip and a conductive target surface. This measurement principle enables the system to capture both static and dynamic shaft conditions, allowing operators to monitor machine position while simultaneously tracking vibration behavior during operation.

Frequently asked questions

Q: What is the exact measurement range of this 8mm probe head?

A: The linear measurement range is 2.0 mm (80 mils). It typically begins at a physical gap of 0.25 mm (10 mils) and ends at 2.25 mm (90 mils) away from the target surface.

Q: Can I use the 330103-00-16-50-12-05 to replace a probe with imperial threads?

A: No. The 330103 base code dictates a metric M10×1 thread. It will not fit into an imperial tapped hole. 

Q: What is the recommended minimum bend radius for the armored cable?

A: To avoid kinking the internal coaxial line or fracturing the armor, maintain a minimum bend radius of 25.4 mm (1.0 inch) during routing.

Q: What physical distance corresponds to a -10.0 VDC gap voltage for the 330103-00-16-50-12-05?

A: On a standard 4140 steel target, -10.0 VDC corresponds to a physical gap of approximately 1.27 mm (50 mils) from the tip of the 330103-00-16-50-12-05 to the shaft.
