Eddy-Current Probe Scaling
The 330171 probe maintains linear displacement scaling with a typical sensitivity of 7.87 V/mm (200 mV/mil). Calibration is referenced to a -10 VDC gap voltage target, ensuring predictable measurement accuracy across rotor dynamics applications. Cross-talk suppression techniques are integrated to minimize interference when multiple probes are installed in close proximity.
Frequently Asked Questions
Q: What is the recommended installation gap for the 330171 probe? A: The recommended gap is 1.27 mm (50 mils) to achieve linear measurement performance.
Q: Can the probe be used in high-temperature environments? A: Yes, the probe is rated for -35 to +177 deg C, suitable for most industrial bearing applications.
Q: How does the FluidLoc connector design contribute to reliability? A: The FluidLoc design prevents fluid ingress along the cable, maintaining signal integrity in harsh environments.
Field Installation Guidelines
- Thread Engagement: Secure the probe using 1/4-28 UNF threads with a minimum of 5 full turns to ensure mechanical stability.
- Cable Routing: Route the integral cable separately from high-voltage or high-current conductors to minimize electromagnetic interference.
- Shield Grounding: Ground shielding exclusively at the Proximitor termination point to prevent ground loop currents.
- Calibration Check: Verify -10 VDC gap voltage reference during commissioning to confirm linear scaling.
- Environmental Care: Maintain probe tip cleanliness; PPS material must not be exposed to abrasive or corrosive contaminants.
- Case Handling: Ensure stainless steel case integrity by avoiding over-torque during installation, preserving thread alignment and sealing.
