Fuji Electric France stands out for the production of remarkably precise pressure transmitters , meticulously engineered to meet the stringent requirements of the nuclear industry.
Fuji Electric's mission is to provide nuclear operators, EPCs and subcontractors with pressure transmitters transmitters to nuclear operators, EPCs and subcontractors, with high accuracy, long-term stability and fast delivery times.
We have delivered differential, absolute and relative pressure transmitters to nuclear power plants and nuclear research centers worldwide.

You're probably wondering why we use nuclear-qualified pressure transmitters .
One of the right questions to ask is: Safety?
What makes them so special?
We're going to take you through the essentials right now.
Fuji Electric sensors are designed and manufactured for accurate and reliable measurement in nuclear facilities.
They are qualified for installation in systems with safety-related functions, whose failure could have serious industrial or radiological consequences.
Fuji Electric's nuclear pressure transmitters have been installed for several decades throughout EDF's French nuclear fleet and in many other power plants around the world, as well as in the latest EPRs commissioned or under construction (Taishan, Flamanville, Olkiluoto and Hinkley Point).
Fuji Electric France's total commitment to nuclear safety includes the implementation of a safety culture approach. It's part of the company's DNA.
The RCC-E provides rules for the design and construction of electrical and control systems for pressurized water reactors.
It defines the technical rules and requirements for :
The RCC-E is drawn up by AFCEN (Association française pour les règles de conception): https://www.afcen.com/fr/rcc-e/187-rcc-e.html
It has been drawn up in partnership with industrialists, engineers, manufacturers, inspection bodies and operators, and represents a compendium of good practice in line with IAEA requirements. AFCEN's members include companies and institutes such as EDF, Framatome, CEA, Bureau Veritas, etc.
Fuji Electric pressure transmitters are qualified to RCC-E.
When you choose a Fuji Electric "nuclear qualified" transmitter, you are assured of meeting your project requirements in terms of :
A nuclear pressure transmitter is built using materials from rigorously selected suppliers, ensuring the high level of quality, traceability and qualification required. Discover 6 essential criteria for ensuring safety with a nuclear pressure transmitter .
Fuji Electric ensures strict quality control during the manufacturing process, including ongoing training and skills management for personnel, traceability of supplies and third-party suppliers, control of manufacturing processes, documentation, and technical support for customers.
Fuji Electric's nuclear pressure transmitters have been qualified to ensure their function and maintain their level of qualification, i.e. maintain their level of performance and operability in the event of a serious accident, for a period of 40 years, and even 60 years for some of them.
Electrical connections are also a key point. For example, we use K2-qualified, quick disconnect 1/4-turn subbases from partners such as SAIB and SOURIAU, themselves long-established players in the French nuclear industry.
All our gaskets and seals are PMUC-certified.
Depending on the type of transmitter and its intended use, e.g. a radiologically demanding area, we offer EPDM gaskets for their high tolerance to irradiation.
The various types of electronics are specially designed to ensure performance and reliability.
The "smart" digital models have undergone rigorous robustness tests, while the "analog" models, without any programmable digital components, guarantee performance and reliability in the most demanding environments (accidental profiles, irradiation, earthquakes & thermodynamic shocks).
In addition to the classic process flange connections, diaphragm seals versions are also available, offering a wide range of connections options:
They are also distinguished by their choice of materials, depending on the nature of the process fluid: 316L stainless steel, Hastelloy C (for seawater applications), membrane with gold+ceramic coatingpressure transmitter for hydrogen applications), etc.
Fuji Electric's range of nuclear-qualified pressure transmitter covers a wide range of applications:
"Category K3-AD" classified or unclassified
Pressure transmitter with diaphragm seal
digital or analoggauge pressure or differential)
"Category K3-A, K3-AD "Classified or unclassified
Digital or analogPressure transmitter (absolute, relative or differential pressure)
The entire Fuji Electric range can also be offered with diaphragm seals . Selection depends on :
| Ambient conditions? | Absence of irradiation, or Presence of ambient and/or accidental irradiation up to 50 kGy |
| Need to qualify for accidental conditions? | NC TAS K3 K3ad |
| Seismic requirements? | Operability Integrity Dimensioning spectrum |
| Service conditions ? | Temperature Pressure Type of fluid and risk of corrosion |
We can thus distinguish two major families of devices that can meet the needs of most applications: | Smart digital transmitter Transmitter with 100% analog electronics and no programmable components (CEP or ANFL) |
The applications are many and varied.
Fuji Electric pressure transmitters are used in almost every area of a nuclear power plant, outside the BR containment. They are used on the secondary circuit, the cooling circuit and in the machine room housing the steam turbine. They are also installed on auxiliary and backup circuits:
The company has delivered over 6,000 units of pressure transmitters (manometric, differential, absolute) to EDF, AREVA, ALSTOM GE for French nuclear power plants, EPR in France, Finland, China and PWR in South Africa or NPCIL in India.
