Pressure Transmitter with HSI-Sensor Recognition

Air Breathers
The pressure transmitter HDA 4748-H with HSI sensor recognition has been specially developed for use in HDA-4748-H Air Breathers
conjunction with measuring instruments HMG 3000 or HMG 3010. For data transmission, the HDA 4748-H has
an HSI interface (Sensor Interface). The HSI sensors are automatically recognized via the HSI interface by the Suction
