The F490 is a loop powered indicator to display the actual process value, range and loop current. The measuring unit to be displayed is simply selected through an alfa-numerical configuration menu. No adhesive labels have to be put on the outside of the enclosure: a weather proof and user friendly solution! The configuration of Span, offset and number of decimals is done through software functions, without any sensitive dip-switches or trimmers. A wide selection of options further enhances the capabilities of this model, including Intrinsic Safety for hazardous area applications.

The input circuit is separated from the backlight circuit. The F490 accepts 4 – 20mA input signals from a wide range of process instruments, including flow (linear or square root), level, pressure and temperature transmitters. All these process parameters can be displayed in their own engineering units.

Advantages
– Robust aluminum or stainless steel 316L field enclosure (IP66, IP67 / NEMA Type4X) .
– It is so rugged, a truck can even stand on it!
– Intrinsically Safe available – ATEX, IECEx and CSA approval for gas and dust applications.
– Familiar easy operation with the Fluidwell “Know one, know them all” configuration structure, saving time, cost and aggravation.
– Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.

Applications
– Applications where a local, loop powered, general purpose display is required without monitoring function, linearization or signal re-transmitting.
– The F490 takes operating energy from an input current (2-wire 4 – 20mA) and has a separated backlight circuit.
