To begin with, the pressure switch EDS 4100 in ATEX version, serves for use in potentially explosive atmospheres. The EDS 4000 series serve as a base for the pressure switch.
The switching point and switch-back point, the function of the switching outputs as N/C or N/O and the switching delay are factory-set according to customer requirement. They are not field-adjustable. In addition, the EDS 4100 in ATEX version has a ceramic measurement cell with thick-film strain gauge. It serves for measuring absolute pressure in the low-pressure range.
What’s more, the pressure switch is available with approval for the following protection types and applications:
- I M1 Ex ia I
- II 1G Ex ia IIC T4, T5, T6
- II1/2G Ex ia IIC T4, T5, T6
- II 2G Ex ia IIC T4, T5, T6
- II 1 D Ex iaD 20 T100 °C
Also, the approvals cover almost all requirements regarding ignition group, error class and temperature class.
Moreover, the versions for other protection types and applications are available on request.
