Description
Optimized for continuous, high-reliability machinery protection, the Bently Nevada 330101-00-08-10-02-CN eddy current transducer provides accurate shaft vibration and position measurements in critical industrial rotating equipment. As a core component of the 3300 XL 8mm Proximity Transducer System, this probe converts physical displacement into proportional voltage signals. Engineered with a 3/8-24 UNF thread, a 0.8-inch case length, and a 1.0-meter total cable length, this imperial-threaded sensor is designed to interface with demanding industrial environments while complying with country-specific regulatory approvals.

Alternative Models & Compatibility
The 330101-00-08-10-02-CN probe represents the 1.0-meter configuration of the 3300 XL 8mm series. To build a standard 5.0-meter system, this probe must be paired exclusively with a 4.0-meter extension cable. For a 9.0-meter system, it requires an 8.0-meter extension cable. Mixing components from different overall system lengths (e.g., using a 5-meter system proximitor with 9-meter system cables) will severely alter the electrical calibration curves and void measurement accuracy.
Application Pitfalls & Engineering Notes
When installing in oil-mist or wet-sump conditions, the miniature coaxial ClickLoc connection point is highly susceptible to fluid-borne high-impedance electrical leaks. To prevent signal attenuation and erroneous gap voltage readings, the connection must be sealed inside a dedicated connector protector or wrapped tightly with high-temperature self-fusing silicone tape. Additionally, avoid routing the probe cable close to high-voltage AC lines to prevent magnetic noise induction on the raw RF signal.
Commissioning & Wiring Tips
During the machine gap setting procedure, verify that the probe tip is clear of side-metal interference. Maintain a minimum physical radial clearance of at least 15.0 mm around the 8 mm probe tip to prevent surrounding structures (such as bearing housings or lock washers) from altering the magnetic field. Use a digital multimeter at the Proximitor sensor output to check that the gap voltage settles around -10.0 VDC (the midpoint of the linear range) before final locknuts are torqued.
Installation Guidelines
CRITICAL WARNING: Prior to probe installation or physical adjustment, ensure the machinery is completely stationary and that the machinery protection system is safely bypassed or powered down. De-energize all high-voltage equipment adjacent to the installation path to prevent accidental discharge or equipment damage.
1
Inspect the threads on the mounting bracket and clean the target track of any debris, oil, or rust to ensure a clean reference area.
2
Thread the probe into the bracket by hand, turning carefully to avoid cross-threading the 3/8-24 UNF imperial housing.
3
Connect the ClickLoc coaxial connector to the extension cable, ensuring the mechanical lock is fully clicked into place.
4
Adjust the gap physically while reading the output voltage. Once the voltage reaches the system specification, torque the locking nut to 4.5 Nm (40 in-lb) maximum to secure the probe assembly.
