HYDAC Electronic pressure transmitter for shipbuilding and offshore HDA 3700
Description:
This pressure transmitter, which has been specially developed for shipbuilding and offshore applications, is based on a very robust and accurate sensor cell with a thin film DMS on a stainless steel membrane. All parts in contact with the fluid are in stainless steel and are welded together. Since no seals are required in the sensor chamber, leakage is eliminated. The 4 .. 20 mA output signal in two conductor technique enables connection to the relevant evaluation electronics. Since the accuracy varies markedly with the temperature of the fluid being measured, this instrument offers outstanding characteristics in this respect. Areas of application are pressure monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.
