Specifications
The gauge pressure transmitter FKR FCX-AIV series stands out for its ability to provide reliable, accurate measurements in the most demanding industrial environments.
Designed to meet the needs of high-pressure applications, the gauge pressure transmitter - high pressure - FKR is capable of withstanding high pressure ranges, up to 150 MPa, while offering enhanced resistance to harsh environmental conditions such as extreme temperatures and corrosive environments. Its material options enable optimum use in aggressive processes.
The high-pressure transmitter also features an optional configurable digital display, making measurements easy to read and enabling simple adjustments via magnetic buttons, without the need to open the housing. Compatible with HARTTM 7 protocol, it ensures seamless integration with modern control systems, enhancing its versatility. Its robust design and international certifications (ATEX, IECEx, cCSAus) make it the preferred choice for critical applications in classified hazardous areas.
