Hardware Specifications

Rotor Dynamics and Signal Conditioning

Consequently, the 330103-08-13-10-02-05 probe executes precise eddy-current field generation to establish highly repeatable probe scaling across its full 2.0 mm linear range. During dynamic shaft rotation, the polyphenylene sulfide tip interacts with the target area to pass low-loss RF signals back to the Proximitor sensor, facilitating continuous gap voltage validation toward nominal -10 VDC targets. Meanwhile, the internal mechanical bonding methods provide robust cross-talk suppression when installing multiple sensors in adjacent configurations. As a result, this design suppresses structural parasitic interference, ensuring clean telemetry transmission for advanced rotor dynamics and asset diagnostics.

Frequently Asked Questions

Q: What is the mechanical difference between the 330103 and 330104 proximity probes?

A: While both belong to the 3300 XL 8 mm system and share identical electrical performance, the 330103 version is built without an outer flexible stainless steel armor layer on the cable. Conversely, the 330104 series features integrated stainless steel armor to shield the cable from abrasive environments.

Q: Can this 1.0-meter integral probe cable connect directly to a 3500 monitor module without an extension cable?

A: No, because the Proximitor sensor requires a specific total loop capacitance tuned to a 5.0-meter or 9.0-meter system length. Technicians must combine this 1.0-meter probe with the corresponding 4.0-meter or 8.0-meter extension cable to preserve the system calibration and maintain the exact 7.87 V/mm scale factor.

Field Installation Guidelines

• Mechanical Threading: First, clean and tap the internal M10 x 1 mounting hole to remove physical obstructions. Next, thread the stainless steel probe body into the bracket while checking the gap voltage with a digital multimeter until the target bias voltage is achieved. Finally, torque the primary jam nuts to lock the orientation.
• Transducer Shielding: Ensure the unarmored cable lead routes away from sharp edges that could tear the insulation jacket. Furthermore, isolate the extension cable outer shield layer, grounding it exclusively at the Proximitor sensor housing ground terminal to stop circulating ground loops.
• Cable Routing: Route the probe cable lead through designated protective pathways using a minimum bend radius of 25.4 mm. Furthermore, separate these low-voltage signal conduits from high-power AC motor supply lines to minimize inductive noise coupling.
