FAQ – Common Questions & Buying Guide
Q1: Can I use a 5-meter probe with any Proximitor?
A: No. 5-meter probes work only with the 5-meter Proximitor sensor.
Q2: What is the difference between 330101 and 330102?
A: 330102 has 3/8-24 UNF armored thread. 330101 is non-armored. Only 330101 supports 3m length for 9m Proximitor.
Q3: My site has low temperature below -40°C. Is this probe suitable?
A: Standard probe works to -52°C, but avoid prolonged below -34°C to protect pressure seal. Use extended temp version for cable above +177°C.
Q4: How do I set the air gap correctly?
A: Adjust probe tip until output voltage reads -9 Vdc. That gives about 1.27 mm gap.
Q5: What happens if I use longer field wiring than 305 meters?
A: High frequency signals will roll off. Check frequency response graphs before exceeding limit.
Q6 (Experienced user): I see drift in warm-up. Normal?
A: Small drift under 3% is typical. For critical apps, allow 30 min warm-up. Replace probe if drift exceeds 5% ASF.
Q7 (Buying guide): Which length probe should I choose?
A: Use 1m (330102-00-20-10) for standard Proximitor. Use 5m only if you have 5m Proximitor sensor. Avoid mixing lengths.
Q8 (Buying guide): Do I need the FluidLoc option?
A: Yes for wet or oily environments. No for clean, dry areas. Option 11 includes FluidLoc.
Q9: Is pressure test included?
A: No. Contact custom design department if your application needs seal testing.
Q10: Can I use this probe with third-party monitors?
A: Not recommended. Use with Bently Nevada 3300 XL Proximitor for specified linear range and accuracy.
