Application-Specific FAQ
Q: Is the PR9268/302-000 compatible with Bently Nevada 3500 monitoring systems?
A: Yes. The passive coil output is electrically compatible with Bently Nevada 3500/42M and similar velocity monitor inputs. Verify input impedance requirements before installation.
Q: What is the difference between PR9268/302-000 and PR9268/200-000?
A: The /302-000 variant features a longer cable pigtail and MIL-spec connector suited for panel-mount installations; the /200-000 is a shorter-lead version for direct-mount applications. Sensitivity and frequency response are identical.
Q: Can this sensor be used in ATEX / hazardous area zones?
A: The standard PR9268/302-000 is not ATEX-certified. For Zone 1/Zone 2 applications, consult EPRO for the appropriate Ex-rated variant or use an approved intrinsic safety barrier.
Q: What is the recommended calibration interval?
A: EPRO recommends functional verification every 12 months as part of a machinery protection system proof-test schedule per IEC 61511.
Q: Do you provide installation and commissioning support?
A: Konmask.com provides technical pre-sales support. For on-site commissioning, contact our engineering team at [email protected].
