Hardware Specifications

Mechanical Monitoring and TSI Characteristics

The 330710 probe system relies on consistent eddy-current probe scaling to convert target gap into a proportional output voltage. During commissioning, gap voltage validation is performed to achieve a -10 VDC target, ensuring the output signal resides within the linear operating band of the Proximitor sensor. To preserve signal integrity in rotor dynamics monitoring, probes must be oriented 90 deg relative to the shaft axis. Effective cross-talk suppression is achieved by maintaining specified physical clearances from adjacent probes, preventing interference from overlapping electromagnetic fields.

Frequently Asked Questions

Q: Can this 1.0 m system length be extended using standard coaxial cables?

A: No. The system is factory-calibrated as a complete loop (Probe, Extension Cable, and Proximitor). Modifying the total cable length changes the electrical impedance, which degrades signal linearity and frequency response.

Q: Is the ClickLoc connector compatible with legacy 3300 series probes?

A: No. The ClickLoc connector is a proprietary interface for the 3300 XL series, providing enhanced mechanical retention compared to previous threaded connector designs.

Field Installation Guidelines

• Mounting: Thread the probe into the mounting bracket or machine casing using the M16x1.5 thread. Tighten the lock nut securely to prevent mechanical movement caused by vibration.
• Cable Routing: Maintain a minimum bend radius of 25.4 mm (1.0 in) for the coaxial cable to avoid damaging the internal dielectric and shield.
• Grounding: Ensure the probe body maintains a clean, metal-to-metal electrical contact with the machine housing to provide a stable reference ground.
• Target Interface: Verify that the target material is conductive (typically AISI 4140 steel) and that the target diameter is at least 30.5 mm to minimize measurement edge effects.
• Calibration: Monitor the Proximitor output with a digital voltmeter during the final gap adjustment to confirm the -10 VDC setpoint is reached at the desired operational gap.
