The pressure transmitter series HDA 4400 has a pressure measurement cell with thin-film strain gauge on a stainless steel membrane.

The output signals 4 to 20 mA or 0 to 10 V enable connection to all measurement and control devices of HYDAC ELECTRONIC GMBH as well as standard evaluation systems (e.g. PLC controls).

The main fields of application are in mobile or industrial hydraulics and pneumatics.
