The EDS 3400 is a compact electronic pressure switch with integrated digital display for relative pressure measurement in the high pressure range.

The instrument has a measurement cell with thin-film strain gauge on a stainless steel membrane. Depending on the particular version, the instrument can have one or two switching outputs, and there is the option of an additional switchable analog output signal (4 .. 20 mA or 0 .. 10 V).

A special design feature of the EDS 3400 is that the display canmore

Additional Information

N/A The 4-digit display can indicate the pressure in bar, psi or MPa. The user can select the particular measurement unit. When changing to a different measurement unit, the device automatically converts all the switching settings to the new unit of measurement.

The EDS 3400 is also available in a variant with menu navigation in accordance with VDMA.

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

Special Features

N/A

  • Switching mode of the switching outputs adjustable (switch point function or window function)
  • Switching direction of the switching outputs adjustable (N/C or N/O function)
  • Switch-on and switch-off delay adjustable from 0.00 to 99.99 seconds
  • Analog output signal selectable 4 to 20 mA or 0 to 10 V
  • Pressure can be displayed in measurement units bar, psi, MPa. The scaling can also be adapted to indicate force, weight, etc..
