Hardware Specifications

Cross-Talk Suppression

The housing assembly design minimizes electromagnetic interference between adjacent probe channels. By maintaining coaxial shielding continuity and mechanical separation, cross-talk suppression ensures accurate eddy-current displacement signals during rotor dynamics monitoring.

Frequently Asked Questions

Q: Can the housing be installed without removing machine covers? A: Yes. It allows external probe adjustment and replacement without opening the machine casing.

Q: Does the housing affect probe calibration? A: No. The housing provides mechanical protection only; calibration remains defined by the probe and Proximitor sensor.

Q: What thread engagement is required for secure installation? A: A minimum of 5 turns on the 3/4-14 NPT thread is recommended for mechanical stability.

Field Installation Guidelines

• Align housing penetration depth with specified probe tip clearance before tightening.
• Ensure NPT threads are engaged with proper torque to prevent vibration loosening.
• Route conduit and fittings per industrial standards to maintain environmental sealing.
• Ground shielding at the Proximitor end only to avoid ground loops.
• Inspect connector protector seals to confirm moisture resistance before commissioning.
