Flow sensor circuits Flow sensor circuits
With the compact device, the intrinsically safe flow sensor circuits are designed as internal
circuits.
When it comes to the remote versions, the intrinsically safe flow sensor circuits are led through.
The maximum permissible safety values of the flow sensor circuits are listed below:
Remote signal converter, sensor circuit (terminal 1 to 7, color coded) Remote signal converter, sensor circuit (terminal 1 to 7, color coded)

INFORMATION!
The verification of intrinsic safety is not necessary for the interconnection of vortex flow sensor
connected to the signal converter, if the cable length doesn't exceed 50 m / 164 ft using the
supplied cable.
