  • Application

    The RIA14/RIA16 field indicators monitor measurement signals and display them with high resolution and accuracy. The indicators feature one open collector output for monitoring a limit value. They permit universal installation and are particularly suitable for use in the field or in mobile rigs.

    Function

    The indicator records an analog measuring signal and shows this on the display. The LC display shows the current measured value digitally and as a bargraph with limit value violation signalling. The indicator is looped into the 4 to 20 mA circuit and obtains the required energy from there.

    Application Example

    a) Explosive hazardous area / Zone 1,2 / Zone 21,22

    b) Non-hazardous area

    c) Transmitter 4 to 20 mA
