Replacement & Compatibility FAQ
Q: Can I replace the PR6424/000-010 CON021 with a Bently Nevada 3300 XL without recalibrating my system?
A: No. The two sensors use different driver electronics and sensitivity curves. A full system recalibration and driver replacement is required. Contact our engineering team for a compatibility assessment.
Q: Is the PR6424/000-010 CON021 interchangeable with the PR6424/000-030?
A: The suffix (-010 vs -030) typically denotes cable length or connector variant. Verify your driver and extension cable specifications before substituting.
Q: Do you supply matched sensor-driver-extension cable sets?
A: Yes. Konmask.com can supply complete matched sets (sensor + CON021 driver + extension cable) to ensure factory-calibrated performance.
Q: What is the lead time for the PR6424/000-010 CON021?
A: Standard stock items ship within 3–5 business days. For urgent requirements, contact us for expedited options.
