PHA220
Pressure transducer for hydrogen applications

PHA223 is equipped with the latest technological innovations developed by EFE
  • Compact Sensor
  • Hydrogen and high pressure compatible
  • One-piece design without welding
  • Qualified according RTCA DO 160
PHA223 is equipped with the latest technological innovations developed by EFE. The stainless steel measuring element is not welded to the sensor fitting. Its "one-piece" design makes the PHA223 sensor compatible with high pressure hydrogen up to 700bar. The processing electronics integrated in the sensor delivers a high level signal of 0.5-4.5V and gives the sensor a very good accuracy: ±0.25% between +10 and +40°C. Compact and robust, it provides all the guarantees for on-board use combining temperature, vibrations and shocks. The PHA223 has been qualified for shock, vibration, magnetism and electrostatic discharge according to the RTCA DO 160 standard.
