1.1 Intended use

The LS 6500 is a hygienic level switch for level detection and dry-run protection for liquids and solids. The device measures liquids such as water and beer and well as viscous and sticky products such as honey or toothpaste. Even dry medias can be measured such as sugar or flour.

The measurement is precise and not affected by the mounting position.

Coating of the sensor or condensate are not detected.

DANGER!

The LS 6500 can be used in hazardous areas. For detailed information refer to ATEX approval on

DEVICE DESCRIPTION 2

2.2 System description

Inputting physical quantities into an SPC or PLC or other computer and control systems requires accurate and reliably working sensors. The sensor is a detecting element that converts physical quantities, such as temperature, level, pressure, conductivity, turbidity and flow, into an electrical signal. Locally further processed, usually by an integrated microcontroller, the measuring signal can be transmitted by analogue (e.g. 4...20 mA loop). The LS 6500 is designed to detect the level of liquids or for pump protecting purposes.
