Baumer LSP Potentiometric Level Transmitter

The level measuring device LSP utilizes the potentiometric measurement principle and can be used in all medias that have a minimum conductivity of 50 µS/cm.

From the low resistive measuring rod a high frequent current is fed through the media to the tank wall. The voltage between the tip of the rod and the tank wall is measured. This output voltage is proportional to the tank filling level.

The measurement is unaffected by temperature and adhesive media. The instrument is ideal for measurements in small wessels with tough, pasty or strong adhesive media, such as ketchup, honey, and toothpaste. The integrated electronics provide a 4 – 20 mA output.

The LSP has automatic recognition of top/buttom mounting position. Even angled installation is possible. In a non-conductive tank such as a plastic tank a reference rod must be installed.
