Dual Channel Monitor series D224 for measurement of speed and ratio for increased safety requirements up to SIL1
The BRAUN Speed and Ratio Monitor Series D224.xx receives input signals from speed sensors or flow rate transmitters. The two specially designed signal inputs fit perfectly to our proven A5S... sensors. However, they can also be used universally to accept any other sensor signal.
The monitor simultaneously measures one or two speed values (or other quantities transmitted as frequency). This input is utilized to compute ratio, difference or sum and thereby to read and monitor such entities as stretch/shrinkage or blend ratio.
Display, setpoints, and analog output may be adjusted to any speed. During its lifetime cycle, the monitor is completely maintenance-free.
