Application-Specific FAQ
Q: Is the 330904-00-09-50-02-00 a direct replacement for the 330900-00-09-50-02-00?
A: Yes, with one caveat – the NSv suffix indicates a non-standard voltage output. Verify your monitor’s input card accepts –2 V to –18 V range before substituting.
Q: What shaft material is required for accurate readings?
A: The probe is calibrated for AISI 4140 steel. Non-magnetic or non-ferrous shafts (e.g., titanium, Inconel) require a correction factor or a target-specific calibration.
Q: Can this transducer be used in a Zone 0 hazardous area?
A: No. The ATEX certification covers Zone 1 and Zone 2 only. For Zone 0 applications, consult Bently Nevada for intrinsically safe barrier configurations.
Q: What is the recommended gap voltage at installation?
A: Set the probe gap to achieve –10 VDC ±0.5 V at the Proximitor output, corresponding to approximately 1.27 mm (50 mil) air gap on 4140 steel.
Q: Does Konmask provide a calibration certificate?
A: Yes. A factory or third-party calibration certificate is included where available. Contact us if a NIST-traceable recalibration is required prior to shipment.
