Instrumentation
Specialist in nuclear instrumentation, ARCYS designs, develops, and maintains measurement solutions tailored to the technical and regulatory requirements of the most critical facilities: PWRs, EPRs, onboard nuclear boiler rooms, and research reactors in France and abroad.
Thanks to our proven expertise, we offer robust and qualified instrumentation (RCC-E, ESPN, etc.) for monitoring essential parameters - temperature, level, radiation, and physical chemistry - in the most demanding environments.
Our level and pressure sensors
The level sensors and differential pressure sensors developed by ARCYS are specially designed to meet the rigorous standards of the nuclear sector. RCC-E certified, they are suitable for PWR and EPR power plants, as well as critical environments exposed to extreme conditions.
Ultra-reliable, robust, maintenance-free, and highly accurate, our sensors ensure continuous and safe operation, even in irradiated areas. Trust ARCYS for durable and high-performance measurement solutions in the harshest environments.

Reliable measuring instruments, adapted to the most demanding nuclear environments
ARCYS offers a range of physicochemical monitoring instruments designed to meet the stringent requirements of nuclear facilities (REP, EPR, INB). Whether dissolved gas analyzers, flow meters, oxygen meters, or sampling systems, our products ensure continuous, reliable, and secure measurement. Some equipment can be combined or supplemented with hardening options, test devices, or advanced sampling modules.
Monitoring of dissolved gases in primary circuits and alternators
This equipment allows for the precise measurement of hydrogen or oxygen concentrations in critical circuits such as the primary of PWRs or the cooling systems of alternators. They play an essential role in nuclear safety and personnel security.
