The pressure transmitter series HDA 7400 combines excellent technical data with highly compact design.

The HDA 7446 was specifically developed for OEM applications, especially for use in confined cavities. A sensor cell with a thin-film strain gauge on a stainless steel membrane is the basis for a robust, long-life pressure transmitter.
