4. Design and function

4.1 Description

The ⊕ and ⊖ media chambers

are separated by an elastic dia-

phragm. The dierential pres-

sure leads to an axial deection

of the the diaphragm against

the measuring range spring.

The deection, which is

proportional to the dierential

pressure, is transmitted to

a movement and in addition

to the plungers of the micro

switches via a pressure-tight

and low friction link.

4.2 Scope of delivery
