Conductivity Based Instruments
Liquid level control in tanks or pipelines
The LSM series of sensors is used to detect level, media failure (dry run protection) or media differences (phase separation) of liquids and some liquid / solid solutions. This allows the sensor to ignore foam or product adhesion errors.
The microwaves emitted by the transmitter becomes subject to a time delay depending on the media. When in contact with a media having a different dielectric constant outside the selected range, an electronic switch is triggered. The probe tips are designed so that even in pipelines with low cross section no major disruption of the flow exists. The LSM 025xS is designed to detect the level of fine solids or granulates with a very low dielectric constant.
