| 摘要 |
A differential pressure switch is described comprising a first (1) and a second (2) inlet for first and second fluids operating respectively on opposite faces of a deformable membrane (3) in such a way so as to determine opposite movements of the membrane (3) for the activation or the disactivation of a sensor (8, 13) as a function of the difference in pressure between the first and the second fluid. Lever means (9) are interposed between the membrane (3) and the sensor (8, 13) so as to amplify the movements being commanded to the membrane (3) in the direction of the sensor (8, 13). <IMAGE> |
