RIA 452 - Panel Meter

Digital process meter in panel mounted housing for monitoring and displaying analog measured values with pump control and batch functions and flow calculaion.

 

The single-channel panel meter RIA452 monitors and displays analog measured values. Pumps can be monitored with the digital status inputs. The measured value is displayed using the seven-digit 14-segment LC display. Numbers and units are displayed in white, the bar graph in yellow, overrange and underrange in red and the limit value flags and digital status inputs in green and yellow. 

The RIA452 can provide power directly to two-wire transmitters connected. You have the option of selecting the input and the transmitter power supply as intrinsically safe for Ex applications. Up to eight freely programmable relays monitor the measured value for limit value overshoot and undershoot. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions (e.g. alternating pump control).

Furthermore, the RIA452 can be used as a preset counter and for measuring flow at open channels and measuring weirs. 

The scalable analog output offers many different ways of forwarding the input signal: zoom function, linearization, offset, inversion and signal conversion (input/output conversion). The optional pulse output gives the user the option of outputting integrated process values.
