Wiring diagram
Insertion and inline sensors are supplied
with voltage by the processor devices
which also process and display the measu-
red signals. Devices with MK96…, MS96…
and MC96… housing styles are available.
The individual housing styles are designed
for different operating voltages and feature
various output and supplementary
functions. For intrinsically safe flow sensors
it is required to use signal processors with
intrinsically safe control circuits, i.e. the se-
ries MS96…Ex… and MC96…Ex… .
