Application-Specific FAQ
Q: Is the 330904-00-15-05-02-00 compatible with the Bently Nevada 3500 Series monitors?
A: Yes. The 3300 NSv probe with 7.87 V/mm scale factor is directly compatible with 3500/40M and 3500/42M monitor modules configured for NSv input.
Q: What is the difference between the 330900 and 330904 series probes?
A: The 330904 series features an 8 mm tip diameter (vs. 5 mm for 330900), providing a wider linear range and improved performance on larger shaft diameters (>50 mm).
Q: Can this probe be used in hazardous (classified) areas?
A: The standard 330904-00-15-05-02-00 is not ATEX/IECEx certified. For Zone 1/Zone 2 or Division 1/Division 2 installations, consult Konmask for the appropriate certified variant.
Q: What target material is recommended for best linearity?
A: AISI 4140 steel is the standard calibration target. For stainless steel shafts (e.g., 316 SS), a target material correction factor must be applied — contact our technical team for calibration data.
Q: Do you offer calibration certificates?
A: Yes. Factory calibration certificates and third-party calibration reports are available upon request for an additional fee.
