Frequently Asked Questions

• • Q1: What gap voltage should I set for this probe?
    A: Target -9 Vdc to -11 Vdc with standard Proximitor. That puts you in the linear range (about 50 mils gap).
  • Q2: Can I use this probe with a 5 meter extension cable?
    A: Yes. Use Bently Nevada extension cables with same impedance (75Ω). Total system length must match Proximitor calibration.
  • Q3: What happens if I exceed max thread engagement?
    A: You may damage the probe tip or case. The probe may not measure correctly. Stay within 0.375 inch.
  • Q4: Is this probe safe for hazardous areas?
    A: See temperature class schedule. It meets EPL Ga/Gc and Dc with proper installation. Use approved barrier if needed.
  • Q5: Why does the probe need -24 Vdc power?
    A: Proximitor sensors require negative voltage for eddy current operation. More positive than -23.5V reduces linear range.

• • Q6: Field tip: How to avoid cable damage near rotating shaft?
    A: Route armor away from moving parts. Use cable clamps every 30 cm. Leave slack for vibration.

• Buying Guide & Tips
  Choose 330172-00-40-05-02-00 when you need a standard 5mm probe with 4-inch case length and 0.5m armored cable. Great for tight mounting spots. We offer 12-month warranty and ship within 12-24 hours via FedEx, UPS, or DHL. Compare with 8 mm reverse mount probes above if you need larger tip. Contact us for custom lengths. Always verify thread engagement and torque limits before installation.
