Abstract (en)
[origin: EP0427585A1] This device comprises a pressure divider (8) which delivers the control pressure (P3) of a valve positioned in a pipe, starting from different pressures (P1, P2), two deformable capsules (A, B) which, as a function of reference signals received, act on a mobile element (9) of the divider (8) with inverse effects to make the pressure (P3) vary as a function of said references, energy supply means (13a, 13b) which are necessary for the variation of the pressure in the capsule (A, B) as a function of the references received, means (12a, 12b) which make it possible to be free from the variation of atmospheric pressure, and a member for control of the means (13a, 13b) receiving a signal transmitted by a probe and transmitting, according to a cycle consisting of a succession of periods of feed and of relaxation of the capsules (A, B), a signal for control of the pressure (P3). <IMAGE>
