Dwyer Instruments IP-43 | Current to pressure transducer | 4-20 mA input | 3-27 psi (20-185 kPa) output
An input signal of current is converted to a linearly proportionate pneumatic output pressure by the Model IP-43 Current to Pressure Transducers. Integrated volume booster, minimal air usage, field reversible output (which yields an output inversely proportional to the input signal), and adjustable zero and span are among the features. Both exterior installation and splashdown are permitted by the robust NEMA 4X enclosure. Applications requiring the functioning of pneumatic valve positioners, damper and louver actuators, air cylinders, web tensioners, clutches, brakes, and final control elements can use this IP.
