Monitoring shaft vibration and dynamic position in critical rotating machinery is the primary function of the Bently Nevada 330101-29-50-10-02-CN proximity probe. Part of the highly standardized 3300 XL 8 mm series, this non-contacting sensor converts the physical distance between the probe tip and a conductive target into an electrical signal when paired with a matching Proximitor Sensor. It features an unarmored cable design with a thread size of 3/8-24 UNF, engineered to withstand aggressive chemical environments and extreme temperatures on industrial machinery trains.

This 1.0-meter probe is engineered for integration within a complete 5-meter or 9-meter 3300 XL proximity transducer system. For a complete system, you must match this probe with the correct length of extension cable (e.g., a 4.0-meter extension cable for a 5.0-meter total system) and a corresponding 3300 XL Proximitor Sensor. Mixing 3300 XL components with older, non-XL 3300 components is technically possible but will result in minor calibration and scale-factor discrepancies (typically altering the standard 200 mV/mil output).
The unarmored coaxial cable is highly sensitive to physical crushing and sharp bends during installation. Ensure a minimum static bend radius of 25.4 mm (1.0 inch) is maintained throughout the cable run. Grounding loops can compromise signal integrity; prevent the coaxial connector outer shell from making electrical contact with the machine casing or junction box metalwork by using the supplied connector silicone sleeve or Teflon heat-shrink tubing.
During mechanical installation, monitor the DC gap voltage directly from the Proximitor Sensor output using a high-impedance digital multimeter. Adjust the physical depth of the probe in the mounting bracket until the DC voltage reads approximately -10.0 VDC, corresponding to the physical midpoint of the linear range (approx. 1.27 mm or 50 mils from the shaft target). Lock the mounting nut to a maximum torque of 13.6 N-m (120 in-lb) to prevent stripping the 3/8-24 UNF threads.
CRITICAL WARNING:
De-energize the machinery and verify the target area is completely stationary before inserting the probe into the mounting port. Accidental contact between a spinning shaft and the probe tip will instantly destroy the sensor and potentially damage the target shaft surface.
