Electro-pneumatic (I/P - E/P) Current/Voltage to Pressure

The Flucon 500 FC Series transducers are ideally used to convert current or voltage input signal to a nearly proportional pneumatic output pressure. This versatile instrument is rugged and reliable force balance transducers for use in both process control and industrial applications, for standard process control applications which typically utilise 3 to 15psig output and industrial & high pressure application which typically utilise pressure output up to 120 psig. Flucon 500FC Series transducers combines low cost, high accuracy and minimum air consumption with field proven technology. Versatile design features and rugged, compact housing with a choice of CMRI and ATEX* approved versions for explosion proof or intrinsically safe operation when used with a suitable barrier.

  Principle of Operation


The Flucon 500 FC Series transducer is a force balance device in which, when electrical current is passed through the coil of transducer magnetic field is created which acts on the magnet assembly, casuing the anvi & diaphragm to move away from or forward the nozzle (flapper nozzle) depending on the direction of current flow. Motion at the nozzle assembly is proportional to the amount of current passing through the coil.

The flapper/anvil move away from or forward towards the nozzle creates back pressure which acts as pilot pressure to an integral booster relay. when input electrical current increases (or decreases for reverse acting) causes proportional output pressure increases.

Zero and Span are calibrated by turning easily accessible adjusting screws on the front face of the unit. The zero adjusting screw causes the nozzle to move relative to the flapper/anvil. The span adjusting screw is a potentiometer that limits the current through the coil. A thermistor circuit in Series with the coil provides temperature compensation.
