FAQ – Experience-Based Answers
- Can I use this probe below -34°C?
No. Exposure below -34°C may damage the pressure seal prematurely. - Does this probe work with 3300 XL 11 mm probes?
Yes. Use it alongside 3300 XL 11 mm Proximity Probes for different shaft diameter needs. - My reading drifts in high humidity. Is this normal?
No. This probe passes IEC 68-2-3 with <3% ASF change at 93% humidity. Drift means a seal or cable fault. - What is the real-life linear start point?
Linear range starts at 0.25 mm from the target. Do not operate below this point. - Can I cut the cable to a shorter length?
No. Cutting changes RPROBE (7.59 Ω) and ruins calibration. Order your exact length.
Buying Guide – How to Select the Correct Probe
- Match thread and engagement: Use 3/8-24 UNF. Max thread engagement is 0.563 inch.
- Pick total length: 1.0 meter (3.3 ft) is standard. Longer cables need monitor adjustment.
- Choose approval: Option 05 (CSA/ATEX/IECEx) covers most hazardous zones.
- Check temperature: Standard probe goes to +177°C. Use extended version above that.
- Avoid pressure seal failure: Do not use below -34°C unless you request a custom pressure test.
