Transducer For Electrical To Pneumatic Output
Transducer For Electrical To Pneumatic Output
Waaree Instruments offers IPW 400X Transducer to Convert Current/Voltage Input to Proportional Pneumatic Output Pressure. This converts current or voltage input signal to a linearly proportional pneumatic output pressure. This versatile instrument is designed for control applications that require a high degree of reliability and repeatability at an economical cost. Optional NEMA 4x (IP 65) version allows for splashdown and outdoor installation. The IPW 400X is available in 2 different versions, the lower range model is designed for standard process control applications, which typically utilise 3 to 15 psig output and the extended range unit provides up to 120 psig output for higher pressure industrial pneumatic and process control system requirements. Principal of operation: the IPW400X transducer is a force balance device in which a coil is suspended in the field of a magnet by a flexure. Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves towards the nozzle and creates back pressure which acts as a pilot pressure to an integral booster relay. Input signal increases (or decreases for reverse acting) cause proportional output pressure increases. Zero and span are calibrated by turning adjust screws on the front face of the unit. Adjustment of the zero screw repositions the nozzle relative to the flexure. The span adjustment is a potentiometer that controls the amount of current through the coil. Special features: compact size, low air consumption, integral volume booster, field reversible, flexible adjustments of zero and span, standard process inputs, split ranging, NEMA 4X (IP 65) enclosure (optional); and low cost.
