Product Introduction
The Epro PR6423/003-040 + CON021 eddy current sensor system is a precision-engineered solution developed for demanding industrial environments that require accurate, non-contact displacement and vibration measurement. This model belongs to Epro’s trusted PR6423 series and is paired with the CON021 converter module, forming a complete proximity probe system widely utilized in rotating machinery protection and condition monitoring systems.
The “003” version in the series is known for its mechanical and thermal stability, making it particularly suitable for elevated temperature environments and long-term monitoring. The sensor has an 8mm diameter probe tip, a 4-meter cable length, and delivers high-resolution displacement data essential for the continuous monitoring of turbines, compressors, motors, and other high-speed rotating equipment.
Compatible with Epro’s MMS series monitoring systems and other standard vibration interfaces, the PR6423/003-040+CON021 system is ATEX-certified for use in hazardous areas and is built to withstand vibration, oil contamination, and electromagnetic interference.

Frequently Asked Questions (FAQ)
-
Q: What distinguishes the “003” version of PR6423 from others?
A: The “003” version is optimized for high-temperature applications and environments where long-term stability is critical. -
Q: Can this sensor be submerged in oil or fluid?
A: Yes, the sensor head is IP68 rated and can operate in oil-lubricated environments without degradation. -
Q: What does the CON021 module do?
A: It converts the eddy current probe’s raw signal into a linearized analog output for connection to monitoring systems. -
Q: Is this system suitable for axial displacement monitoring?
A: Yes, it can be used for both axial and radial measurement depending on installation geometry. -
Q: How is the probe installed?
A: Via threaded insertion into a sensor port, usually with an M10 × 1 or 3/8” UNF thread, depending on spec. -
Q: Can the sensor withstand vibration during operation?
A: Yes, it is specifically designed for continuous operation in high-vibration environments such as rotating machinery. -
Q: What cable length options are available?
A: This model has a 4.0-meter cable, but other lengths (e.g., 1m, 2m, 5m) are available depending on configuration. -
Q: Is recalibration required after replacing the probe?
A: Typically not, provided the replacement probe has identical specifications and factory calibration. -
Q: Does it support remote monitoring systems?
A: Yes, when connected through CON021, it outputs analog signals that can be fed into SCADA or DCS systems. -
Q: Can it detect shaft rubbing or rotor contact events?
