■ Process pressures p1 und p2 are applied to the media chambers ⊖ (2) and ⊕ (3).
■ Measuring cell (4) is filled with transmission liquid.
■ Differential pressure across ⊕ and ⊖ pressure sides deflects the diaphragm (1) and displaces the transmission fluid .
■ The deflection of the connection rod (5) is converted through the use of a transmitting lever (6) into rotation, which is transferred over an axial shaft (7) to the movement (9).
■ The torque pipe (8) seals, assuring a frictionless path from the measuring cell.
■ Overpressure protection in both directions up to the max. total pressure applied is provided by contoured metal bolsters.
