  • Application

    The process indicator RIA15 gathers measurement signals and displays them with high resolution and accuracy. The process indicator is suitable for a wide variety of applications e.g. in switch rooms, cabinets, laboratory instrumentation as well as in plant and apparatus construction.

    Function

    The RIA15 process display unit is looped into the 4 to 20 mA current loop and measures the transmitted current. The parameterization of the measurement range, the decimal point and the offset can easily be done with the help of three keys on the device. The setting can be done during operation. The measured value indication occurs via a five digit 7-segment LC display. With the optional HART® function up to four measured values of one measurement instrument can be indicated.
