Mechanical Monitoring and TSI Integration
The PR6424 sensor utilizes eddy-current induction to determine the proximity of a ferromagnetic shaft. To maintain valid rotor dynamics data, the system requires precise eddy-current probe scaling, ensuring the voltage output accurately tracks the 4 V/mm sensitivity rating. During installation, users must perform gap voltage validation, targeting a -10 VDC offset to ensure the probe remains within its linear measurement range. The system incorporates cross-talk suppression by utilizing shielded PTFE cabling and Lemo-plug termination, which prevents electromagnetic interference from corrupting the high-frequency dynamic signal required for eccentricity and key-phasor speed detection.
Frequently Asked Questions
Q: Can the cable length of the PR6424/010-100 be modified in the field?
A: No. The PR6424 sensor and CON021 converter comprise a factory-calibrated signal chain. Modifying the 5 m cable length will alter the system impedance and resonant frequency, leading to significant errors in measurement accuracy and linearity.
Q: What is the requirement for the shaft material monitored by this sensor?
A: The sensor is calibrated for ferromagnetic steel (42 Cr Mo4 standard). Monitoring shafts constructed from non-ferromagnetic materials will result in non-linear responses and reduced measurement sensitivity, requiring factory recalibration.
Field Installation Guidelines
- Mounting: Secure the sensor within a rigid, non-vibrating bracket. Use the M18x1.5 thread for positioning, ensuring the probe tip is clear of the shaft surface throughout all operational conditions.
- Gap Adjustment: Establish the nominal 2.7 mm air gap using a calibrated feeler gauge. Verify that the sensor is positioned at the center of its linear range to allow for both radial and axial shaft excursions.
- Grounding and Shielding: Route the armored coaxial cable away from high-voltage power lines and VFD drive outputs. Terminate all cable shields to a dedicated instrument ground bus to mitigate noise induction.
- Connector Maintenance: Inspect the Lemo-plug connections for moisture or conductive debris. Ensure the self-locking mechanism is fully engaged to prevent intermittent signal loss caused by vibration.
