よくある質問 (FAQ)
Q1: What is the main difference between the 3300 XL 11 mm and 8 mm sensors?
A1: The 11 mm version provides a longer linear measurement range, making it suitable for axial and thrust applications.
Q2: Can I use the 3300 XL 11 mm system with older 7200 series parts?
A2: No, all components must be replaced with 3300 XL 11 mm series parts for compatibility.
Q3: What mounting options are available?
A3: Panel mount, DIN rail mount, and versions with no hardware are available.
Q4: What are the hazardous area certifications?
A4: Certified for ATEX, IECEx, SIL 2/3, and North American hazardous areas.
Q5: What is the total system length for 330780-91-05?
A5: The system length is 9.0 meters.
Q6: What type / cable does it use?
A6: A 75 Ω triaxial cable with FEP insulation, available in armored and FluidLoc options.
Q7: What is the recommended gap setting?
A7: 2.5 mm (100 mils).
Q8: Is the sensor affected by RFI/EMI?
A8: No, it has enhanced imm台y and complies with CE requirements.
Q9: Is special s/tware needed for configuration?
A9: Yes, the monitoring system (e.g., 3500) must support the 3300 XL 11 mm series.
Q10: Can the connector be exposed to oil?
A10: Silicone tape should not be used in oil-exposed areas; use connector protectors instead.
