Equipped with an extensive range of functionalities and approvals the RIA45 and RIA46 indicators suit any application in the process industries. Typical applications include displaying and monitoring process values, e.g. where overspill protection is required.

As a panel display the RIA45 is ideal for installation in control rooms, switch cabinets or laboratories while the RIA46 field indicator can be installed within hazardous areas.


The indicator detects, evaluates and displays analogue process values. The integrated loop power supply provides power supply to two-wire sensors. Universal inputs allow measuring of current and voltage as well as providing a direct connection to RTDs and thermocouples. For purposes of process control, limit points can be monitored and corresponding integrated relays can be activated. The dual line LC display has been developed especially for the process industries and provides a wide range of information which is programmable. Upon pushing the quick information button the display manually or automatically switches through the various values (process, calculated or memory-values). In the event of a failure the colour of the display alternates to signal an alarm, which is easily visible from distance. The integrated application package "differential pressure" allows a quick, convenient and easy initiation in differential pressure applications.
