4.1 Measuring principle
Fig. 1: Measuring principle
The unit operates on the impedance spectroscopy method. It analyses
the electrical behaviour of the media to be monitored in the frequency
range between 50 and 200 MHz. The probe tip generates an electrical
field that is influenced by the level. The nature of the medium as well as
build-up or foam have different electrical properties that are used for the
evaluation.
4.2 Other features of the unit
•
Streamlined sensor geometry, no blockage of the pipe when unit types with short probe are used,
no pressure loss.
•
Orientation-independent installation possible.
•
Defined position of the cable entry for angled sockets when ifm welding adapters are used.
