Eddy-Current Scaling and Gap Voltage
The 330104-00-17-05-02-00 operates as part of an eddy-current transducer chain with a matching Proximitor Sensor and extension cable. The probe converts changes in the electrical gap between the probe tip and conductive shaft target into a displacement-related output from the Proximitor Sensor.
The specified system scale factor is 7.87 V/mm (200 mV/mil) +/- 5%. Therefore, installation requires the probe-to-target gap to remain within the specified linear measurement region. The resulting signal supports both static shaft position and dynamic shaft vibration measurements.
The ClickLoc connector uses a vibration-resistant locking arrangement. In addition, the TipLoc and CableLoc construction secures the probe tip and cable assembly against mechanical loading.
Frequently Asked Questions
Q: Does the probe measure vibration directly?
A: The probe senses dynamic changes in the gap between the probe tip and conductive target. The associated Proximitor Sensor converts these changes into an electrical signal representing shaft displacement.
Q: What linear measurement range applies to the 3300 XL 8 mm system?
A: The specified linear range is 2 mm (80 mils), approximately from 0.25 mm to 2.3 mm (10 to 90 mils).
Q: What connector does this configuration use?
A: This configuration uses a miniature coaxial ClickLoc connector with standard cable.
Field Installation Guidelines
Install the probe with its sensing axis directed toward the conductive measurement target. Maintain the probe gap within the specified linear region during normal shaft operation.
Route the integral probe cable away from high-current power conductors and other sources of electrical interference. Avoid sharp bends, excessive mechanical tension, and repeated movement at the cable-to-probe connection.
Connect the probe to the matching 3300 XL Proximitor Sensor and verify the complete transducer chain before placing the machinery monitoring channel into service. Check the gap voltage and signal scaling against the applicable system installation requirements.
Use appropriate shielding and grounding practices for the complete transducer circuit. Keep probe, extension-cable, and Proximitor connections clean and mechanically secure.
