Diaphragm pressure switches 3.40 ATEX flameproof enclosure

3.40 - II 2GD

Diaphragm pressure switches ATEX flameproof enclosure

These flameproof electrical apparatus comply with European Directive ATEX 94/9/EC, for group II and category 2 GD.
They are suitable for a variety of uses in hazardous zones 1, 2, 21 and 22 in which the use of flameproof instrument is required.
The sensing element is a metallic diaphragm and acts directly on the microswitch through a self-centering pivot.
The simplicity of the design, without levers, cams or similar mechanisms, gives the unit an exceptionally long working life
