Application-Specific FAQ
Q: Is the 31000-28-05-15-030-00-02 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. This probe assembly is designed for use with the 3300 Series Proximitor drivers, which interface directly with the 3500 Series monitoring rack via standard coaxial signal loops.
Q: Can this probe be used in hazardous (Zone 1 / Division 1) areas?
A: Certain 3300 Series configurations carry ATEX/IECEx certification. Please confirm the specific variant suffix with our technical team before installation in classified areas.
Q: What is the recommended gap voltage for this probe?
A: The nominal operating gap is typically set to −10 VDC (approximately 1.0 mm gap), with alarm and danger setpoints configured per API 670 guidelines in the monitor.
Q: Do you provide calibration certificates?
A: Factory calibration documentation is available upon request. Third-party NIST-traceable calibration can be arranged for critical applications.
Q: What is the difference between the 31000 and 330100 series probe part numbers?
A: The 31000 series designates the complete housing assembly including the probe body and integral cable. The 330100 series refers to the probe tip only. Ensure you order the correct assembly for your installation bracket configuration.
