Next Generation of Display with Control Unit

Finally the time has come: The new RIA45 and RIA46 displays the first two devices of the new 4-wire platform are presented. The goal of this family is the consolidation of all typical functions of a transmitter, a control unit with relays and the features of outstanding displays inside a control panel or in the field.

Due to a favorable basic price as well as a progressive pricing of the options, an extremely attractive price-performance-ratio is offered.


The devices offer an intuitive operation guaranteeing easy and quick commissioning. Amongst other things this is realized with the application packages for standard 1-channel-operation, standard 2-channel operation and differential pressure measurement. The application packages provide default values of parameters and assist in commissioning. Additional comfort is provided through the parameterization via FieldCare and the USB port of the PC.
