Abstract: Servo pressure pickup comprising a sealed housing having a pressure inlet and in which is mounted an anaroid capsule one wall of which is mechanically linked to an electrical displacement measuring device. The current feed of an electromagnet is controlled by the measuring device. The electromagnet includes a movable core interposed between the capsule and the displacement measuring device. The electromagnet is designed to generate a force in opposition to that produced by the expansion of the capsule and proportional to the feed current of the electromagnet from the measuring device. The displacement measuring device may be amplified and used to generate an analog or a digital pressure measurement output signal.
