Application-Specific FAQ
Q: Is the PR6424/013-130 CON021 a direct replacement for Bently Nevada 330101 series probes?
A: The PR6424 series uses the same 8 mm tip diameter and -24 VDC supply standard, making it functionally compatible with most Bently Nevada 3300/3500 monitor inputs. Always verify gap voltage calibration curves before installation.
Q: What is the maximum cable run from probe tip to driver with CON021?
A: The CON021 extension cable is designed to work within the EPRO-specified total cable system length. Consult the PR9268 driver datasheet for maximum combined probe + extension + driver cable length (typically 5 m or 9 m system configurations).
Q: Can this sensor measure axial position as well as radial vibration?
A: Yes. The PR6424/013-130 CON021 is suitable for both radial vibration and axial (thrust) position measurement when installed per OEM shaft orientation guidelines and paired with an appropriate monitor channel configured for position measurement.
Q: Do you supply calibration certificates?
A: Calibration documentation from the original manufacturer is available for new units. For surplus/refurbished stock, third-party calibration can be arranged — contact us for details.
Q: What target materials are compatible?
A: The sensor is calibrated for AISI 4140 steel. Performance on other ferromagnetic or non-ferromagnetic materials will vary; recalibration is recommended for non-standard target materials.
