Wiring diagram
Functional principle
Signal processors not only supply insertion
and inline sensors with voltage, they also pro-
cess and display the measured signals. De-
vices with MK96…, MS96… and MC96…
housing styles are available. The individual
housing styles are designed for different oper-
ating voltages and feature various output and
supplementary functions. For intrinsically safe
flow sensors it is required to use signal pro-
cessors with intrinsically safe control circuits
of the series MS96…Ex… and MC96…Ex… .
