• 04: 40 mm overall case length.

• 10: 1.0 meter (3.3 feet) total length.

• 02: Miniature coaxial ClickLoc connector with standard cable.

• CN: CSA, ATEX, and IECEx agency approval rating.

Hardware Specifications

Rotor Dynamics and Measurement Integrity

Accurate monitoring of rotor dynamics is dependent on correct eddy-current probe scaling. This 8 mm probe must be integrated into a calibrated system to maintain linear displacement output. During commissioning, installers must perform gap voltage validation to ensure the probe tip operates at the nominal -10 VDC target within the linear measurement range. Cross-talk suppression is maintained by the system's high-frequency carrier signal, allowing multiple probes to be installed in proximity without inducing mutual interference in the vibration data.

Ordering Information

• 1 x 330103-00-04-10-02-CN Proximity Probe.

• 1 x Mounting nut set (factory included).

Installation Guidelines

• Probe Mounting

• Thread the probe into the mounting hole until the target gap distance is achieved.

• Adjust the gap to the manufacturer-specified voltage (-10 VDC) using a digital multimeter at the Proximitor terminal.

• Secure the probe using the included locknuts to prevent mechanical drift during machine operation.

• Cabling

• Avoid excessive mechanical strain on the ClickLoc connector during routing.

• Ensure the coaxial cable is shielded and isolated from high-voltage AC paths to prevent induced noise.

Frequently Asked Questions

• What is the function of the CN approval suffix?

  The CN suffix indicates that the probe is certified for use in hazardous environments according to CSA, ATEX, and IECEx standards.

• Is recalibration required when replacing a probe?

  Yes, due to variations in transducer impedance, the Proximitor must be recalibrated whenever a probe is replaced to maintain system accuracy.

• Can I use this probe with a standard Bently Nevada 3300 XL Proximitor?

  Yes, this probe is designed for full compatibility with 3300 XL 8 mm Proximitor sensor systems.

• What is the minimum unthreaded length?

  The 00 suffix indicates the probe has 0 mm of unthreaded length, meaning the threads extend to the base of the probe tip.

• How do I verify the connector is locked?

  The ClickLoc connector provides a tactile and audible click when correctly engaged, ensuring electrical continuity.

• Is the 8 mm probe interchangeable with 5 mm or 11 mm probes?

  No, the 8 mm probe is specifically matched to the inductive properties of its corresponding Proximitor and is not interchangeable with other probe diameters.

• What is the impact of magnetic interference?

  Eddy-current probes are sensitive to ferromagnetic materials; ensure the probe is not mounted in proximity to magnets or concentrated electromagnetic fields.

• Can the cable be field-terminated?

  Field termination is not recommended as it compromises the impedance matching and shielding integrity of the coaxial assembly.
