Frequently Asked Questions (FAQ)
-
Is the 330101-00-24-10-02-05 probe compatible with older Bently systems like 7200 series?
→ No, it is designed specifically for use with the 3300 XL series extension cables and Proximitor® sensors only. -
What material should the monitored shaft be made from for optimal accuracy?
→ The standard calibration is based on 4140 steel; deviations require custom calibration. -
Can this probe be installed in high-temperature environments?
→ Yes, it supports up to +177°C operating temperature, making it suitable for hot machinery. -
Is this probe suitable for underwater or submerged conditions?
→ No, it is not rated for continuous submersion, although it resists moisture and oil splashes. -
How do I verify if the probe is working correctly in the field?
→ Field test can be done using a calibrated dial micrometer and Bently Nevada signal tester or monitoring module. -
What is the correct gap voltage at mid-range for this probe?
→ Typically around -10 VDC at 1 mm gap, but exact values may vary based on target material. -
Is it safe to route the probe cable near high-voltage power lines?
→ It’s not recommended. Use proper shielding and routing to avoid EMI interference. -
Can I cut or extend the probe cable in the field?
→ No, the cable length is factory-calibrated. Cutting or altering will void accuracy and warranty. -
Does the probe require regular recalibration?
→ No recalibration is needed under normal conditions, but periodic verification is advised. -
Is the probe safe to use in hazardous areas (explosion-proof zones)?
→ It can be used in hazardous areas when installed with suitable barriers and certified enclosures.
