Primary coil
The sensor measures the conductivity and temperature of liquids, and optional calculates con-
centration values.
Sensor operation utilizes the inductive sensing principle without mechanical or process-interfer-
ing components.
The hole in the sensor tip is surrounded by 2 coils. The primary coil is supplied with AC voltage.
The secondary coil measures the induced current of the fluid in the measuring hole. The fluid's
temperature is measured at the Pt100 sensor tip. This will ensure temperature compensation of
the conductivity signal.
