Application-Specific FAQ
Q: Is the 21000-16-05-00-066-03-02 compatible with the Bently Nevada 3500 rack?
A: Yes. The 3300 XL proximity system is fully compatible with the 3500/42M Proximitor Monitor and all 3500-series rack components.
Q: Can I use a different extension cable length with this probe?
A: No. The probe, extension cable, and driver are factory-matched as a system. Substituting cable lengths will alter the scale factor and invalidate calibration. Always order a matched set.
Q: What target material is required for accurate measurement?
A: The 3300 XL system is calibrated for AISI 4140 steel. Other ferromagnetic alloys may require a correction factor. Consult Bently Nevada application note 141-108-V1 for target material guidelines.
Q: Is this unit suitable for Zone 0 hazardous areas?
A: The standard 21000-16-05-00-066-03-02 is rated Zone 1 / Division 1. For Zone 0 applications, contact Bently Nevada for intrinsically safe barrier configurations.
Q: Do you provide calibration certificates?
A: A certificate of conformance is included. NIST-traceable calibration certificates can be arranged at additional cost – please inquire at time of order.
Q: What is the typical MTBF for this transducer system?
A: Bently Nevada rates the 3300 XL system at >100,000 hours MTBF under normal operating conditions, making it one of the most reliable proximity systems in the industry.
