Description
The Bently Nevada 330103-00-10-10-02-CN is a non-contact eddy-current proximity probe belonging to the 3300 XL 8mm Transducer System family. This sensor is engineered to measure static displacement (such as thrust shaft position) and dynamic displacement (such as radial shaft vibration) on critical rotating machinery. The probe interacts with a conductive metal target (standard calibration matches AISI 4140 steel) to provide an analog output voltage directly proportional to the physical gap distance.

Engineering Context & Implementation Notes
Proximitor Tuning and Total System Length
The -10 (1.0 meter) integral probe cable must be paired with an appropriate extension cable to match the input specification of the 3300 XL Proximitor Sensor.
- For a 5.0-meter system: Pair this probe with a 4.0-meter extension cable.
- For a 9.0-meter system: Pair this probe with an 8.0-meter extension cable.
Critical Rule: Mismatching the overall combined physical length of the probe and extension cable will shift the electrical resonant frequency of the tank circuit inside the Proximitor, rendering the standard 200 mV/mil calibration invalid and inducing severe measurement errors.
Mechanical Clearances & Cross-Talk Prevention
When fabricating the counterbore holes or mounting brackets for the M10 x 1 threaded housing, verify that the surrounding bracket metal remains outside the probe tip’s electromagnetic field. Maintain a minimum clear space radius of at least 15 mm (0.6 inches) around the probe tip. If multiple proximity probes are mounted in close proximity (e.g., X-Y radial vibration configurations), separate the probe tips by at least 40 mm (1.6 inches) to eliminate magnetic cross-talk interference between the channels.
Frequently Asked Questions
What is the exact difference between this model and the 330103-00-14-10-02-CN?
The difference lies entirely in the overall case length. This module contains a 100 mm case length (-10), whereas the 14-variant contains a 140 mm case length (-14). Both share identical unthreaded options (0 mm), total cable lengths (1.0 meter), connector types, and regional approvals.
Can I shorten the 1.0-meter integral cable if it is too long for my junction box?
No. Cutting, splicing, or mechanically shortening the proprietary triaxial cable alters its inherent electrical impedance and capacitance. This permanently ruins the sensor’s linear calibration range. Excess cable length must be loosely coiled (avoiding tight bends sharper than a 25.4 mm or 1.0 inch radius) and secured within the local housing or conduit box.
How do I verify if the probe has suffered an internal failure using a multimeter?
Isolate the probe from the extension cable and measure the resistance between the center conductor pin and the outer
