Adjustment of the zero screw repositions the nozzle relative to the flexure. Zero and Span are calibrated by turning adjust screws on the front face of the unit. Input signal increases (or decreases for reverse acting) cause an accurate proportional change in output. As this assembly moves towards the nozzle, it creates backpressure, which acts as a pilot to an integral booster relay. ![]() Current flowing through the coil generates movement of the flexure.
