A housing (4) has a chamber (5) divided into two spaces by a membrane (6), with two channels (3) connecting each space with conduits on each side of the throttle. The pressure difference is connected crossways over the membrane, and a spring (8) is fitted in one space with an end directed towards the membrane. A ferro-magnetic component is fixed to the membrane, and an electrical sensor is fitted opposite in the other space. The sensor moinotors a position for the ferro-magnetic component, and emits a signal electrically when the position is taken up. The component is a permanent magnet (1), and the sensor comprises a Hall effect indicator (2). The spring used is of the screw type, and at its end opposite to the membrane has an axially adjustable holder (7). |
