Process indicator with pump control

RIA452 Process indicator with pump control ©Endress+Hauser

Digital process meter in panel mounted housing for monitoring and displaying analog measured values

The process meter monitors and displays the analog measured values. Pumps can be monitored with the digital status inputs. The RIA452 can provide power directly to two-wire sensors connected. Up to eight freely programmable relays monitor the measured value. Other operating modes for the relays include sensor or device malfunction, batch and pump control functions. Furthermore, the RIA452 can be used as a preset counter and for measuring flow at open channels and measuring weirs.
