Application-Specific FAQ
Q: Is the PR6423/011-010 compatible with Bently Nevada 3500 series monitors?
A: Yes. The EPRO PR6423 series uses the same signal conditioning standard as Bently Nevada proximity probes and is electrically compatible with 3500/42M and similar cards when used with the CON021 driver.
Q: What shaft materials are supported?
A: The standard PR6423 is calibrated for AISI 4140 steel. For stainless steel (316L) or Inconel shafts, a recalibration or alternative probe variant is required — contact us to confirm.
Q: Can this sensor be used in ATEX Zone 1 environments?
A: Intrinsically safe (IS) variants of the PR6423 series exist. Confirm the exact suffix and associated IS barrier requirements with our technical team before specifying for hazardous areas.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock or new-production units, lead time is 4–8 weeks. Contact us for current availability.
Q: Do you provide a warranty?
A: Yes. All units carry a 90-day functional warranty from date of shipment. Extended warranty and on-site support can be arranged for project contracts.
