ABSTRACT:
In an electropneumatic transducer, an adjustment spring is used for offsetting the coil in relation to a pneumatic system leakport simply and without hysteresis. One end of the spring supports the suspension element on which the coil is positioned. The offset adjusting spring includes a folded region near the end mounted to the transducer body. A screw mechanism is positioned to compress the sides of the fold toward each other when turned in one direction and allow the sides of the fold to open when turned in the opposite direction. Movements of the sides of the fold flex the adjustment spring, causing the offset to vary adjustably.
