HDA 4700 with HART interface is a digital pressure transmitter which is used to measure relative pressures in hydraulics and pneumatics. In addition to the analogue output of the measured value, digital communication is possible by means of the HART protocol.

This pressure transmitter, which is based on the HDA 4700 series, has a very accurate and robust sensor cell with a thin-film strain gauge on a stainless steel membrane.

Due to their outstanding temperature and EMC characteristics, together with their compact dimensions, these instruments can be used in a wide range of applications.

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