FAQ

Q1: What type of signal does the 3300 XL 8 mm Proximity Probe produce?

A1: It generates a variable AC signal proportional to the displacement between the probe and target shaft.

Q2: Can this probe operate in explosive environments?

A2: Yes, it can be paired with intrinsically safe barriers for hazardous area applications.

Q3: How do I verify probe installation alignment?

A3: Use a micrometer or feeler gauge to measure the probe tip gap relative to the shaft and ensure it matches system specifications.

Q4: What is the typical cable length available?

A4: Standard cable length is 1 meters, with options for custom lengths upon request.

Q5: Is this probe compatible with older 3300 Series systems?

A5: It is primarily designed for 3300 XL systems but may be compatible with previous models using proper adapters.

Q6: What is the maximum vibration frequency it can measure?

A6: The probe supports up to 25 kHz frequency response, suitable for high-speed machinery monitoring.

Q7: How does temperature affect the measurement signal?

A7: The probe maintains accuracy within -40°C to 120°C; extreme temperatures may slightly affect signal amplitude but remain within operational tolerance.

Q8: Can the probe measure both displacement and vibration simultaneously?

A8: Yes, when integrated into the 3300 XL system, it can provide both shaft displacement and vibration data.

Q9: What is the recommended mounting method for optimal performance?

A9: Threaded mounting on a rigid support or using a clamp mount near the rotor shaft is recommended for stable measurements.

Q10: How do I prevent electrical noise from affecting the probe signal?

A10: Use shielded cables and proper grounding techniques as outlined in the 3300 XL system installation guide.
