General description

5.2.1.

construction

The 8041 transmitter comprises an electronic module and a PVDF
or stainless steel measurement sensor.
The measurement sensor comprises two electrodes and a magnetic
system.
Electrical connection is made via two cable glands by means of a
6-pin terminal block.
The 8041 transmitter requires an 18-36 VDC power supply and has:
• one frequency output;
• one relay output;
• one 4-20 mA current output.
5.2.2.

principle of operation

The magnetic system in the measurement sensor generates a mag-
netic field in the fluid, perpendicular to the flow direction, see Fig. 1 .
The electrodes on the measurement sensor ensure electrical contact

Description
with the fluid. When the fluid flows over them, a voltage is measured
between the two electrodes. This voltage is proportional to the fluid
velocity.
