The Epro PR6423/013-030 + CON021 is a high-performance eddy current sensor system designed for non-contact, highly accurate monitoring of shaft displacement, vibration, and position in rotating machinery. With a standard 8mm probe diameter and paired with the versatile CON021 converter, this model belongs to the well-established PR6423 series by Epro (a brand under Emerson).

Tailored for critical industrial applications like turbines, compressors, and motors, this sensor is essential for vibration monitoring and protection in condition-based maintenance systems. The PR6423/013-030 variant features a 3-meter cable, making it suitable for medium-distance installations without sacrificing signal integrity. It is often integrated with Epro’s MMS monitoring systems (e.g., MMS 6000/3000), offering a reliable solution for early fault detection and machinery diagnostics.

FAQ

1. What is the main difference between the PR6423/013-030 and other PR6423 variants?

   The “030” in the part number denotes a 3-meter pre-attached cable length, ideal for mid-range installations.

2. Can this sensor be used in high-temperature areas?

   Yes, the sensor operates reliably up to +180°C, and the CON021 converter is typically installed in a cooler area.

3. Is CON021 necessary for the sensor to work?

   Yes, CON021 is the signal conditioning unit that converts raw sensor data into standardized output signals.

4. What kind of equipment does this sensor support?

   It supports turbines, compressors, fans, motors, and other high-speed rotating machinery.

5. How does the sensor get mounted?

   Via threaded or flanged fittings on machine bearing housings or shaft casing areas.

6. Can this be integrated with non-Epro monitoring systems?

   Yes, the output from the CON021 can be connected to compatible third-party systems (typically 4–20 mA or voltage signals).

7. How often should the sensor be recalibrated?

   Under stable conditions, it typically requires no recalibration over several years.

8. What certifications does the sensor system hold?

   It is certified for CE, ATEX (Zone 0/1 with accessories), and IECEx environments.

9. Is the cable replaceable in the field?

   No, the cable is factory-integrated to ensure signal integrity. Field splicing is not recommended.

10. How is signal noise or EMI handled?

    The system is highly shielded and grounded to minimize electromagnetic interference (EMI) and noise.
