EDS 4100 Electronic Pressure Switches ATEX Intrinsically safe, programmable

The programmable pressure switch EDS 4100 in ATEX version has been specially developed for use in potentially explosive atmospheres and is based on the EDS 4000 series.

The switching point and switchback point, the function of the switching outputs as N/C or N/O and the switching delay are user programmable in conjunction with the HYDAC Programming Unit HPG 3000.

As with the industry model, the programmable EDS 4100 in ATEX version has a ceramic measurement cell with thick-film strain gauge for measuring absolute pressure in the low pressure range.

With approval for the following Protection types and applications:

I M1 Ex ia I
II 1G Ex ia IIC T4, T5, T6
II 1/2G Ex ia IIC T4, T5, T6
II 2G Ex ia IIC T4, T5, T6
II 1 D Ex iaD 20 T100 °C

almost all requirements are covered regarding ignition group, error class and temperature class.

Versions for other Protection types and applications are available on request.

Special features:

• Switching point and switch-back point user-programmable
• Accuracy ≤ ± 0.5% FS B.F.S.L.
• Certificates: DEKRA EXAM BVS 07 ATEX E 041 X
• Very small temperature error
• Excellent EMC characteristics
• Excellent durability

Setting options:

In conjunction with the HYDAC Programming Unit HPG 3000, all the settings are combined in an easy-to-follow menu.

Setting ranges for the switch outputs:

The switch point (upper switch value) on all instruments is between 5 % and 100 % of the measuring range and the switch-back point (lower switch value) is between 1 % and 96 % of the measuring range

The increment for all instruments is 8 ms.
