HDA 4700 with HART interface is a compact pressure transmitter with flameproof enclosure which is used to measure relative pressures in hydraulics and pneumatics. The triple approval in accordance with ATEX, IECEx and CSA enables universal, world-wide utilization of the devices in potentially explosive atmospheres.

The pressure is detected by means of a very accurate and robust sensor with a thin film strain gauge on a stainless steel membrane. In addition with the analogue 4 .. 20 mA output of the measured value, digital communication is possible by means of the HART protocol.

The instrument provides the option of a temperature sensor. The temperature signal is given out as a digital signal via the HART protocol, the pressure signal is still available as an analogue signal (4 .. 20 mA).
