LS 72xx series
The hygienic conductive sensors type LS 7000 series are used for level detection or dry run protection on conductive liquids. These sensors pick up the electrical resistance of the tank product when the electrode is in contact with the product. The wall of the vessel or the pipe acts as reverse potential. Available are stump electrodes for pipe installation (LS 7200/7201) or mono or multiple rods (LS 7210-7240) for installation in tanks. The sensor rods are from stainless steel or coated, to make them insensitive for foam or product build up. Sensor rods can be shortened without special tools. The electronics is either integrated in the electronic compartment or can be placed in the panel room (electronic modules LEM 100/200). On varying products (with different conductivities), the sensitivity can be adjusted via a contact input. With a huge variety of hygienic process connections, a crevice free installation can be achieved. These connections are EHEDG approved regarding their simple cleanability.
