RIA141 Field display

Digital field loop powered display unit with explosion proof enclosure

Areas of application

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