Hardware Specifications

Mechanical Monitoring and Transducer Dynamics

The 330104 probe utilizes high-frequency radio waves to measure the gap between the probe tip and a conductive target. This system is critical for maintaining accurate rotor dynamics data, specifically in monitoring shaft vibration and position. The probe tip is manufactured from polyphenylene sulfide (PPS), ensuring chemical resistance and stability in demanding environments. Precise eddy-current probe scaling is achieved when matched with the appropriate 3300 XL Proximitor sensor, typically calibrated to a linear range of 2 mm (80 mils). During installation, technicians must ensure the gap voltage validation aligns with the nominal -10 VDC targets to provide the required linear range for journal bearing clearance monitoring.

Frequently Asked Questions

Q: Can the 330104 probe be used with older 3300 series Proximitor sensors?

A: No. The 3300 XL 8 mm probe system is designed specifically for 3300 XL Proximitor sensors. Using these probes with legacy 3300 series components will result in signal inaccuracies due to impedance mismatches.

Q: Is the ClickLoc connector assembly field-repairable?

A: No. The ClickLoc connector is factory-molded to the coaxial cable. Any attempt to cut or splice the cable will alter the system's characteristic impedance and degrade the linearity of the output signal.

Field Installation Guidelines

• Proximity Mounting: Ensure the probe is mounted in a rigid bracket to minimize structural resonance. The probe tip must be clear of any interference to maintain a valid linear range.
• Torque Specifications: When installing the probe, ensure the lock nuts are tightened to the manufacturer's specified torque. Over-tightening may cause deformation of the probe case.
• Cable Routing: Route the coaxial cable through shielded conduit to prevent electromagnetic interference. Maintain a minimum bend radius of 25 mm for the coaxial cable to avoid internal center conductor damage.
• Grounding: Ensure the probe tip is electrically isolated from the machine housing if required by the installation drawing, utilizing the appropriate isolation kit to prevent ground loop currents.
