Présentation du produit
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 sur 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.
