Eddy-Current Probe Scaling and Gap Voltage Validation

The 330105-02-12-05-02-00 assembly applies an alternative housing interface for reverse-mount positions where a rear entry sleeve secures the element inside the machine shell. The 8 mm PPS tip generates an RF field to achieve eddy-current probe scaling over a 2.0 mm linear range. Operational accuracy depends on gap voltage validation during local mechanical installation. Field personnel must adjust the threaded mounting sleeve depth until the static output across the matching Proximitor reads the defined -10 VDC targets. This alignment registers the target surface inside the optimal sector of the scale factor loop, ensuring precise capture of rotor dynamics while maintaining cross-talk suppression against adjacent radial or axial transducers inside the same bearing housing.

Frequently Asked Questions

Q: How does the short 0.5 metre total probe length affect matching extension cables and Proximitor tuning?

A: The proximity transducer system requires a fixed electrical length of either 5.0 metres or 9.0 metres. A 0.5 metre probe must be paired exclusively with a matching extension cable (such as a 4.5 metre or 8.5 metre model) to satisfy total network impedance and prevent errors in eddy-current probe scaling.

Q: What are the consequences of letting fluid contaminants access the ClickLoc coaxial connector?

A: Moisture or oil ingress at the coaxial junction degrades the insulation resistance of the 75 Ohm line. This causes drift during gap voltage validation and distorts higher frequency components critical for assessing complex rotor dynamics.

Field Installation Guidelines

Reverse Housing Mechanical Fit: Install the probe through the rear entry bore or housing block. Thread the casing into position by hand to prevent thread binding on the AISI 303/304 stainless steel barrel.
Static Gap Verification: Connect the 0.5 metre lead to the matched extension cable linked to an active Proximitor Sensor. Read the output with a voltmeter and advance the probe body into the mount until the loop reports exactly -10 VDC.
Locknut Mechanical Anchoring: Tighten the rear locking sleeve or nut to preserve position against structural vibration. Keep the voltmeter monitored during this step to verify that the tightening torque does not shift the probe head away from its target baseline.
Coaxial Routing and Ground Isolation: Route the flexible lead through oil-resistant conduit. Ensure the cable maintains a static bend radius greater than 25.4 mm, and secure the ClickLoc connection within an insulated terminal box to prevent grounding against the machine frame.
