Huba Pressure sensor for shipbuilding 522

The compact type 522 pressure transmitter for shipbuilding is based upon the Huba Control developed thick film technology where the pressure measuring cell is fully welded. The pressure measuring cell incorporates a fully welded construction within the transducer housing. Highest requirements in various applications concerning burst can be met. All pressure transmitters of type 522 have the most important certifications for the shipbuilding industry.
