Description
1. Product Overview
The Emerson EPRO CON021 converter paired with the PR6424/010-120 sensor represents a high-precision solution for Condition Monitoring of critical rotating machinery. This system is designed to measure the relative displacement between a stationary sensor and a rotating shaft without physical contact.
The PR6424 sensor (8mm tip diameter) captures high-frequency electromagnetic field changes caused by shaft movement, while the CON021 driver/converter transforms these changes into a linearized voltage signal. This output is directly proportional to the distance (d) between the sensor tip and the target surface. This setup is a staple in MMS6000 and CSI 6500 protection systems, adhering to API 670 standards for industrial safety and reliability.
Key Applications:
- Shaft Vibration: Real-time monitoring of radial vibration in high-speed turbines.
- Axial Position: Measuring the thrust/axial float of rotors to prevent mechanical contact.
- Speed & Keyphase Detection: Providing pulse signals for RPM calculation and phase analysis.
- Eccentricity: Monitoring shaft bow or thermal warping during turbine startup.

7. FAQ
Q: What does the “/120” in the sensor model signify?
The suffix 120 typically indicates a total system length of 12.0 meters (including the sensor’s integral cable and any required extension cable) to match the electrical characteristics required by the CON021 converter.
Q: Can I use a CON021 with a PR6423 sensor?
Yes, but the CON021 must be calibrated for the specific sensor type and tip diameter. Using a converter tuned for an 8mm probe (PR6424) with a 10mm probe (PR6423) will result in incorrect sensitivity and non-linear data.
Q: Why is the output voltage negative?
Most eddy current systems use a negative DC supply (e.g., -24V). The output moves toward zero as the gap decreases.
