The basic pressure sensing element can be configured as a C-shaped Bourdon tube (A); a helical Bourdon tube (B); flat diaphragm (C); a convoluted diaphragm (D); a capsule (E); or a set of bellows (F).

Controllers are used to regulate positive or negative (vacuum) pressure. They receive sensor inputs, provide control functions ... Mechanical deflection devices such as diaphragms, Bourdon tubes or ...
