Hardware Specifications

TSI Mechanical Monitoring and Signal Integrity

The housing maintains the rigid spatial orientation required for accurate eddy-current probe scaling. Consistent rotor dynamics analysis depends on the housing's ability to prevent mechanical vibration transmission to the probe assembly itself. Proper gap voltage validation, targeting -10 VDC at the linear range center, is achieved only when the probe is locked securely within the housing. Operators must ensure cross-talk suppression by maintaining specified distances between adjacent housings, preventing electromagnetic interference from contaminating the shaft displacement signals during high-speed operation.

Installation Guidelines

• Surface Preparation: Clean the mounting boss to ensure a flat, stable interface for the housing base.

• Thread Engagement: Utilize thread lubricant to prevent galling; ensure a minimum of 5 full threads of engagement.

• Locking Mechanism: Tighten the lock nut firmly once the probe gap is set to prevent mechanical drift during machine operation.

• Grounding: Ensure the housing is properly bonded to the machine case to maintain a low-impedance path for signal shielding.

Frequently Asked Questions

• Does the housing provide electrical isolation? No, the housing is metallic; isolation must be provided by external probe mounting hardware if required.

• Can this housing be used in high-pressure oil environments? Yes, ensure the O-ring is installed correctly to maintain a seal against operating pressures.

• How do I determine the correct gap? Use a feeler gauge between the probe tip and the shaft during the initial housing installation and lock-nut tightening.

• Is the housing material compatible with corrosive atmospheres? The stainless steel construction provides high resistance to oxidation in standard industrial environments.

• Can I adjust the probe depth after the housing is locked? No, the locking nut must be loosened to allow for probe movement; ensure the probe gap is validated after re-locking.

• What causes signal drift in this assembly? Loose lock nuts or mechanical settling of the mounting surface can lead to gap drift and measurement errors.

• Can this housing support armored cables? Yes, the rear thread configuration is designed to interface with standard flexible metal conduit systems.

• Is the housing repairable? The housing is a precision-machined mechanical component and is not repairable if threads or sealing surfaces are damaged.
