Working principle
The measuring cell is a homogeneous sealed body all in
PEEK. Through the body is a hole, through which the media
flows. Built-in around the hole are two coils; a primary coil
supplied with an AC voltage and a secondary coil, which
picks up a small signal through the media induced voltage.
The size of this voltage is dependent on the conductivity of
the media. This signal is amplified and handled in the elec-
tronics to a linear analogue 4...20 mA output signal. Also
built into the body is a Pt100 sensor placed in the tip of the
sensor. This is measuring the media temperature to enable
temperature compensation of the conductivity signal, which
is very temperature dependent. The Pt100 sensor signal is
also available as an analogue 4...20 mA output signal.
The coils and sensor are encapsulated in the PEEK sensor
body, with surface roughness (Ra) <0,8 μm. It is therefore
well suited for use in hygienic processes or direct in con-
centrated acids or alkalis.
