SDU-5000 Stepper Motor Driven Regulators
The SDU-5000 series offers unique and practical method of controlling pressure or vacuum electronically. This is accomplished by interfacing a stepping motor and gear box to a modified 800 or 900 series subminiature regulators. A calibration report included with every unit provides a detailed test data including a scale factor that corresponds to a slope that will yield a open loop accuracy including linearity, repeatability and hysteresis, of +/- 3% FS. The unit can also be interfaced with Airtrols 4103/4104 series spring biased comparators.
