Why Choose the Original Model
- Factory-certified accuracy – calibrated to Emerson’s tight tolerance standards for eddy-current measurement chains.
- System-validated – tested and approved for use within Emerson Epro vibration monitoring systems.
- Long-term availability – Emerson maintains spare parts programs for legacy industrial installations.
- Warranty & traceability – genuine parts include full documentation, batch traceability, and manufacturer warranty.
- Regulatory compliance – meets CE and RoHS requirements for industrial deployments in regulated environments.
Typical Applications
- Turbine shaft displacement and vibration monitoring
- Compressor and pump rotor position measurement
- Machine tool spindle runout detection
- Power generation and petrochemical plant condition monitoring
- Integration with Emerson Ovation, DeltaV, and third-party DCS/SCADA platforms
System Compatibility
The PR6426/010-040 CON021 is designed to work within the Emerson Epro PR6426 eddy-current sensor system. It is compatible with:
- Emerson PR6426 series proximity sensors
- Emerson CON0xx series signal conditioning modules
- Standard 4–20 mA analog input cards on Siemens, ABB, Honeywell, Yokogawa, and Rockwell Automation PLCs/DCS
- Bently Nevada 3500 series (signal-level compatibility; verify loop impedance)
Selection Guide
Use the following criteria to select the correct PR6426 variant for your application:
- Measurement range – confirm gap range (e.g., 0–10 mm, 0–40 mm) matches your sensor-target geometry.
- Output type – select 4–20 mA for long cable runs; voltage output for short-distance, high-speed applications.
- Connector type – CON011 / CON021 / CON031 differ in connector configuration; match to your existing wiring harness.
- Hazardous area – if installation is in Zone 1/2 or Div 1/2, specify ATEX/IECEx-rated variants.
- Redundancy – for critical machinery, consider dual-channel configurations with voting logic.

Replacement & Compatibility FAQ
Q: Can I use CON011 instead of CON021?
A: CON011 and CON021 share the same core electronics but differ in connector type. Verify your cable termination before substituting.
Q: Is the PR6426/010-040 CON021 still in production?
A: Emerson periodically updates its Epro product line. Contact Konmask.com to confirm current availability and lead times.
Q: Can this converter work with non-Emerson sensors?
A: It is optimized for Emerson PR6426 sensors. Third-party sensors with matching output impedance and sensitivity may be compatible, but full system validation is required.
Q: Do you provide installation support?
A: Yes. Our technical team can assist with wiring diagrams, parameter configuration, and system integration guidance. Contact us at support@konmask.com.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on Emerson’s supply chain.
