Features
The pressure transmitters of Type 555 have been specifically developed for use in mobile hydrogen applications and are certified according to EC79/2009. These high-pressure sensors are designed to meet the requirements of hydrogen measurement tasks in mobility applications. The sensor is available with protection ratings of IP67 or IP69K and features a compact and robust design that complies with the shock and vibration resistance requirements of the automotive standard ISO 16750. The measuring cell is based on the thick-film technology on stainless steel developed by Huba Control. It is seal-free and hermetically welded to the pressure sensor, ensuring high reliability and durability.
