Admittance level switches from Hycontrol work with a considerable build up on the probe without false switching. They can distinguish between a coating and product level.Description
The Hycontrol Admittance Probe MD Series uses very similar technology to that of capacitance to detect the product level based on the dielectric properties of the media but has an additional reference probe. 
This offers the ability to ignore product build-up on the sensing probe to prevent false switching. This unique design utilises a protective insulation electrode between the conventional main electrode and the grounding sleeve, which enables the electronics to distinguish between coatings and actual product level.
- low maintenance - no moving parts
