Frequently Asked Questions

• Q: What does ETR stand for in the 330192-00-30-10-00 probe?
  A: ETR means Eddy Current Transducer. This is Bently Nevada's terminology for their 8mm proximity probe system. The probe measures shaft vibration and position using eddy current principle.
• Q: What is the unthreaded length rule for this 3.0 inch case probe?
  A: Unthreaded length must be at least 0.8 inches less than case length. With 3.0 inch case and 0.0 inch unthreaded length, the difference is 3.0 inches. This exceeds the 0.8 inch requirement, so the configuration is valid.
• Q: Can I use the 330192-00-30-10-00 below -34°C (-30°F)?
  A: Bently Nevada warns that exposure below -34°C may cause premature pressure seal failure. For cold environments, consider the extended temperature range probe or contact Bently for special sealing options.
• Q: Is this probe pressure tested before shipment?
  A: No, standard 3300 XL probes are not pressure tested prior to shipment. If your application requires pressure seal verification, contact Bently Nevada's custom design department to request testing.
• Q: What does the 30-10 in the model number mean?
  A: 30 means 3.0 inch overall case length from mounting shoulder to probe tip. 10 means 1.0 meter total cable length including the armored section. This combination provides a compact probe for standard mounting depths.
