The HDA 4700 is a compact pressure transmitter (intrinsically safe version) which is used to measure relative pressures in hydraulics and pneumatics. The double approval in accordance with ATEX and IECEx enables universal, almost worldwide utilization of the devices in potentially explosive atmospheres.

The pressure is measured by means of a very accurate and robust sensor with a thin-film strain gauge on a stainless steel membrane.

The main fields of application are in the oil & gas industry, gas turbines. The device is also used in mining applications as well as in locations with high dust contamination
