Hardware Specifications

Rotor Dynamics and Signal Conditioning

Consequently, the 102044-00-28-10-02 probe executes wide-aperture eddy-current field generation to establish dependable probe scaling across its 4.0 mm linear range. During dynamic shaft rotation, the 11 mm polyphenylene sulfide tip interacts with the target area to deliver low-attenuation RF signals back to the Proximitor sensor, sustaining continuous gap voltage validation toward nominal -10 VDC targets. Meanwhile, the mechanical head layout maintains active cross-talk suppression when engineers place adjacent probes in close proximity. As a result, this shielding configuration blocks parasitic side-view interference, ensuring clean wave path transmission for advanced rotor dynamics and thrust position diagnostics.

Frequently Asked Questions

Q: Why does the 11 mm probe feature a lower average scale factor than standard 8 mm probes?

A: Because the 11 mm probe utilizes a larger physical diameter tip, it projects a wider eddy-current field to achieve a broader 4.0 mm linear range. Consequently, this geometric expansion cuts the nominal scale factor in half to 3.94 V/mm (100 mV/mil).

Q: Can this 7200-series probe interface directly with a modern 3300 XL Proximitor sensor?

A: No, because the internal electrical tuning and core impedance parameters differ significantly between product generations. Mixing the 7200 probe with a 3300 XL sensor alters the system calibration curve and shifts the baseline voltage away from nominal values.

Field Installation Guidelines

• Mechanical Threading: First, clean and clear the internal 1/2-20 UNF-2A mounting port threads. Next, thread the stainless steel probe body into the bracket while monitoring the gap voltage until the physical gap matches the midpoint of the linear range. Finally, torque the jam nuts to lock the sensor body into position.
• Transducer Shielding: Ensure the integral stainless steel armor floats cleanly without making contact with structural machine components. Furthermore, isolate the extension cable outer shield layer, terminating it only at the Proximitor sensor housing ground block to stop noise from entering the signal loop.
• Cable Routing: Route the armored cable lead through dedicated channels using a minimum bend radius of 25.4 mm. Furthermore, separate these sensor paths from high-power AC distribution lines to eliminate inductive noise coupling.
