Field of application
The process measuring device monitors and displays the analog measured values. Pumps can be monitored using the digital status inputs. The RIA452 can supply connected two-wire sensors directly with power.
The RIA452 can supply connected two-wire sensors directly with power, optionally intrinsically safe. Up to eight freely programmable relays monitor the measured value for exceeding or falling below limit values. Other operating modes for the relays are sensor or device faults, batch and pump control functions (e.g. alternating pump control). In addition, the RIA452 can be used as a preset counter and for flow measurement in open channels and measuring weirs.
Benefits
7-digit 14-segment LC display, large bar graph with overrange and underrange
Digital status inputs for pump monitoring
Flow measurement for open channels and weirs
Intrinsically safe input with integrated loop power supply
Min/Max value saved
Linearization table with up to 32 support points
