Eddy-Current Probe Scaling and Gap Voltage
The 330104-00-06-20-01-00 uses the eddy-current measurement principle of the 3300 XL 8 mm system. The probe senses the electrical interaction between its active tip and a conductive target, while the associated Proximitor sensor converts the resulting gap-dependent response into a voltage signal.
The stated incremental scale factor is 7.87 mV/um (200 mV/mil), with a 2.0 mm nominal linear measurement range. Therefore, installation must establish the specified probe-to-target gap before the monitoring channel enters service.
Frequently Asked Questions
Q: What mechanical thread does the 330104-00-06-20-01-00 use?
A: The probe uses an M10 x 1 metric thread and has a stainless steel probe case.
Q: What signal scaling does this probe provide?
A: The specified incremental scale factor is 7.87 mV/um (200 mV/mil), with +/- 6.5% typical tolerance.
Q: What is the operating temperature range?
A: The specified operating range is -51 deg C to +177 deg C for the standard probe.
Field Installation Guidelines
Install the probe with the M10 x 1 threaded body securely positioned in the machine mounting arrangement. Set the probe-to-target gap according to the 3300 XL system installation requirements and verify the resulting electrical output through the associated Proximitor sensor.
Route the armored cable away from high-current power conductors and other sources of electromagnetic interference. Avoid sharp bends, excessive mechanical loading, and damage to the FEP outer jacket. Keep connector interfaces clean and fully engaged before commissioning.
For shielded signal wiring, follow the grounding and shielding arrangement specified for the complete 3300 XL transducer channel. Verify probe polarity, connector engagement, cable continuity, and channel calibration before placing the vibration or position measurement loop into operation.
