Admittance Level Switch MD Series

Admittance Level Switch MD Series

The Hycontrol range of ADMITTANCE LEVEL SWITCHES provide simple, accurate and reliable level control for a wide range of applications. They are suitable for use on liquids, solids, slurries, pastes, granules, powders, and pellets in high temperature, high pressure and corrosive environments.

The main advantage offered by using this admittance range of switches is their ability to ignore product build up on the sensing probe.

This unique design utilizes 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.

This technology also provides an ideal solution for interface detection applications such as oil on water and liquid detection underneath a layer of foam.
