Designed to meet the challenges of very high-pressure environments - hydrogen test benches, industrial injection, petrochemical circuits or power plants - the FKR gauge pressure sensor guarantees reliable, safe measurement while integrating easily into your installations.
Summarize this article with :
In critical environments, the slightest measurement drift can impact the entire production line. Thanks to its piezoresistive technology and optimized digital electronics, the FKR pressure transmitter offers an accuracy of ± 0.065% of the set measurement range.
What's more, it delivers precise pressure measurement over the entire applied pressure range.
Its excellent long-term stability significantly reduces the frequency of recalibrations. Its high reactivity instantly captures rapid process variations.
This level of high-pressure sensor accuracy gives you continuous, reliable measurements that enhance safety, reduce unplanned downtime and improve the efficiency of your high-pressure systems.
Designed to meet the most demanding challenges, the FKR high-pressure sensor is available in two versions:
These two models thus cover all industrial needs without multiplying the number of references, while guaranteeing optimum precision over the entire measurement range.
Thanks to their great rangeability, these pressure transmitters avoid the need for multiple instruments, and guarantee optimum accuracy over the entire measurement range. Measurement range adjustment remains simple via the HART interface or local display, facilitating maintenance and measurement continuity as your requirements change.
For applications involving hydrogen, Fuji Electric offers the FKR high-pressure transmitter in a version with a gold coating on the diaphragm.
This gold coating forms the pressure transmitter 's dense, chemically inert barrier to hydrogen: its crystalline structure slows down the diffusion of hydrogen atoms (H₂), limits leakage and protects the membrane from corrosion. By preventing hydrogen from embrittling the metal, it extends sensor life and preserves measurement reliability even during repeated pressure cycles.
This makes the FKR high-pressure hydrogen sensor the preferred choice for test benches, electrolyzers and hydrogen filling stations, where reliability and safety are paramount.
The FKR gauge pressure transmitter relies on two proven alloys to withstand the harshest environments:
Thanks to the combined robustness of the two alloys, Fuji Electric's high-pressure transmitter withstands pressure cycles, vibration and erosion, maintaining its performance over the long term, even in the most corrosive environments or under extreme pressure.
Thanks to the three magnetic buttons integrated into the local display, the pressure transmitter can be configured without opening the housing or interrupting the process. A simple magnetic stylus can be used to set zero, scale or run diagnostics, even in ATEX environments.
Coupled with the HART protocol (version 7), control of the sensor extends to the control room: technicians adjust parameters remotely, monitor trends and validate tests without having to travel.
These two features not only save time on every job, but also help maintain the durability of your high-pressure systems.
In addition to these features, the new FKR gauge pressure sensor is SIL2/3 and ATEX certified.SIL qualification, as defined byIEC 61508, ensures the reliability of safety systems and minimizes nuisance shutdowns, while ATEX conformity guarantees direct installation in potentially explosive areas without the need for heavy or costly additional protection.
Thanks to these two compliances, Fuji Electric's pressure transmitter - high pressure integrates easily into your installations, protects your teams and equipment, and simplifies your regulatory compliance procedures.
By combining constant pressure measurement accuracy, open connectivity to supervision and a non-contact configuration designed for safety, the FKR gauge pressure transmitter offers a complete response to the requirements of high-pressure applications: technical performance, ease of operation and operational peace of mind.
