Compact Electronic Air Pressure Regulator

Aug. 28, 2006
Current-to-pressure (I/P) and voltage-to-pressure (E/P) Type 900X transducer is now available with zero-based units ranging from 0-7.5 psi to 0-60 psi outputs. The Type 900X approved by Factory Mutual (FM) and the Canadian Standards Association (CSA) as intrinsically safe, is also now compliant with the ATEX directive 94/9/EC for equipment intended for use in potentially explosive atmospheres in Europe. The Type 900X uses an innovative internal control and feedback system which provides accurate conversion of an electrical signal to a linear proportional output pressure. Guaranteed accurate to +/- 0.10% of span, this series of transducers is loaded with features, plus, is rugged and versatile. Output pressures of up to 100 psig can be direct/reverse acting, full/split rangable. Maximum supply pressure of up to 100 psig does not need to be pre-regulated. Integral volume booster provides high airflow capacity of up to 12 scfm. The Type 900X series is available in port sizes of _ NPT (pneumatic) and _ NPT (electric). ControlAir’s Type 900X series is tough and versatile. Housed in a NEMA 4X (IP65) enclosure that’s ideal for remote locations and harsh environments, this transducer has a modular design that allows the user to wall, pipe, panel, DIN rail and manifold mount. The compact size provides for high-density mounting. Front and back porting provides piping flexibility. Electrical connections can be made with pigtail, DIN 43650 connector or terminal block. Calibration is simplified by the inclusion of a noninteractive zero and span. The 900X series can be calibrated, mounted, wired, and in operation quickly and easily for a variety of applications, including the outdoors or in washdown environments. Applications include valve actuation, pneumatic valve positioners, cylinders, clutches, brakes, dampers, louvers, pumps, web tensioning, flow and speed control.
