Engineering Advantages
- Dual-channel architecture enables simultaneous X–Y plane measurement for full orbit analysis without additional hardware
- Non-contact eddy current sensing eliminates mechanical wear and provides sub-micron resolution across the full speed range
- Configurable alarm logic supports both latching and non-latching relay modes to match plant safety philosophy
- Wide temperature tolerance (-20°C to +70°C) ensures reliable operation in both climate-controlled control rooms and harsh field enclosures
- Direct compatibility with EPRO MMS 6000 / CON021 rack systems reduces integration engineering time
- Isolated analog outputs allow direct connection to DCS, PLC, or historian without signal interference
System Architecture & Signal Flow
The PR6424/000-030-CN CON021 operates within the EPRO MMS 6000 modular monitoring platform. Eddy current probes (PR6424 series) are mounted radially at 90° intervals on the shaft. The monitor conditions raw proximity signals, applies configurable filtering, and outputs calibrated vibration amplitude (µm pk-pk or mil pk-pk) via isolated 4–20 mA loops to the plant DCS. Simultaneously, onboard relay contacts provide hardwired Alert and Danger signals to the machinery protection logic solver. The CON021 rack interface card handles backplane communication, power distribution, and system-level diagnostics.

Technical FAQ
Q: Is the PR6424/000-030-CN CON021 compatible with Bently Nevada 3500 series racks?
A: The PR6424/000-030-CN CON021 is native to the EPRO MMS 6000 platform. It is not a direct plug-in replacement for Bently Nevada 3500 rack cards, but the 4–20 mA analog outputs can interface with any DCS or safety system regardless of rack brand.
Q: What probe gap and sensitivity settings are factory-configured?
A: Default factory configuration targets a 1.0 mm nominal gap with standard EPRO PR6424 probe sensitivity (8 mV/µm). Custom gap and sensitivity settings can be specified at time of order.
Q: Can this monitor be used for axial position measurement?
A: No. The PR6424/000-030-CN CON021 is optimized for radial shaft relative vibration. For axial thrust position monitoring, refer to the EPRO PR6426 or PR9268 series.
Q: What is the typical lead time for in-stock units?
A: In-stock units ship within 3–5 business days after order confirmation. For project quantities, please contact us for a dedicated delivery schedule.
Q: Do you provide calibration certificates?
A: Factory calibration records are available for new units. Third-party NIST-traceable calibration certificates can be arranged upon request at additional cost.
