The EDS 3400 is a compact electronic pressure switch with an integrated digital display for relative pressure measurement in the high-pressure range. The instrument has a stainless steel measurement cell with a thin-film strain gauge. What’s more, the instrument can have one or two switching outputs and there is the option of an additional switchable analogue output signal (4 .. 20 mA or 0 .. 10 V).

Moreover, a special design feature of the EDS 3400 is that the display is movable in two planes. The installation of the device can be in almost any position. Plus, it’s possible to turn the display to the optimum position without the usual additional expense of a mechanical adapter. Also, the 4-digit display can indicate the pressure in bar, psi or MPa.

Furthermore, the user can select the particular unit of measurement. When changing to a different measurement unit, the instrument automatically converts all the switching settings to the new unit of measurement. In addition, the EDS 3400 is also available in a DESINA®-compliant version.

The main applications of the EDS 3400 are primarily in hydraulics and pneumatics, as well as in refrigeration and air conditioning technology.
