Flow Measurement
SITRANS F M
Transmitter TRANSMAG 2 with sensor 911/E
3/106
Siemens FI 01 · 2014
Sensor cables between sensor and transmitter
The signal voltage proportional to the flow and present at the
electrodes of the EMF is only a few µV to mV. Superimposed on
this are electrochemical interferences resulting from the contact
between the electrodes and liquid, and which can be up to sev-
eral Volt. Also frequently superimposed are line frequency inter-
ferences, interferences resulting from vibrations on the pipelines
or signal cables, as well as strong magnetic fields in the vicinity.
Sufficient shielding must therefore be provided, as well as fixed
routing of the signal cables (electrode and magnet current ca-
ble) in the case of remote versions. This also applies to devices
with integral preamplifier (smartPLUG). The cable length be-
tween the sensor and transmitter must not exceed 100 m
(328 ft).
Attention must also be paid to the cable routing. Signal cables
must be routed free of vibration, and protected against strong
magnetic and stray fields. In case of doubt, the sensor cables
must be routed in earthed steel conduit.
