FAQ
Q1: What is the operating frequency range of the probe?
A1: The 3300 XL 8 mm Proximity Probe is designed for frequencies up to 10 kHz, suitable for typical machinery monitoring applications.
Q2: Can this probe measure both displacement and vibration?
A2: Yes, when integrated with the 3300 XL system, it can provide both static displacement and dynamic vibration measurements.
Q3: What is the typical target material for accurate readings?
A3: Ferrous metals such as steel or iron are optimal; non-ferrous materials may require calibration adjustments.
Q4: How does cable length affect signal quality?
A4: Signal integrity is maintained up to 30 m using standard coaxial cables; longer lengths may require signal conditioning.
Q5: Is the probe affected by ambient electromagnetic interference?
A5: The probe features shielded coaxial cable and robust design to minimize EMI effects in industrial environments.
Q6: Can it operate continuously at high temperatures?
A6: Yes, the probe can operate continuously up to 120°C (248°F) without performance degradation.
Q7: What type of connector does it use?
A7: The standard configuration uses an integral connector compatible with the 3300 XL monitoring system; cable lead options are available.
Q8: How precise is the linearity of measurement?
A8: The probe offers ±1% full-scale linearity over its measurement range.
Q9: Does it require periodic calibration?
A9: Routine verification against a reference standard is recommended; the probe itself is stable over long periods.
Q10: Can it be used in explosive atmospheres?
