7. FAQs (10 Q / A)

Q1: What distinguishes 330850‑91‑CN from 330850‑91‑05?
A1: The “CN” suffix indicates a regional variant tailored for Chinese market compliance, while “05” indicates full international approvals. Their measurement behavior is largely the same.

Q2: Why select the 9.1 m reach (91) version?
A2: To accommodate installations where the module must be placed some distance from the probe, such as in separate control rooms, remote panels, or to avoid vibration/noise zones.

Q3: What does the “CN” suffix imply?
A3: It implies local/regional labeling, compliance, or packaging suited for the Chinese market or required local approvals.

Q4: Is 330850‑91‑CN compatible with other 3300 XL components?
A4: Yes. It uses the same probe interface, extension cable standards, and output behavior as other 3300 XL 25 mm components, enabling seamless integration.

Q5: What is the measurement linear range?
A5: The linear displacement window is approximately 0.25 mm to 25 mm; beyond that, output may turn non‑linear or saturate.

Q6: What are the physical size and weight?
A6: The proximitor module measures ~78 × 60 × 65 mm, weighs ~0.22 kg; packaged, shipping weight is about 1.8 to 2.0 kg.

Q7: How strong is its EMI / RFI protection?
A7: It has industrial-grade shielding and filtering to preserve signal integrity under high electromagnetic noise, though not specialized for extremely harsh emission zones.

Q8: Can it be calibrated in the field?
A8: Yes — zero/span can be adjusted in the field, provided appropriate calibration tools and reference standards are used. Factory calibration ensures optimal performance.

Q9: What is the estimated service life?
A9: With proper installation, environment control, and maintenance, it typically operates reliably for many years, often 5–10+ years.

Q10: Can it measure non-ferrous targets accurately?
A10: The sensor is optimized for ferrous metal (steel, iron) surfaces. Using non-ferrous materials may reduce sensitivity or accuracy and is not recommended for critical monitoring.
