1 Introduction
1.1 Intended Use
Level switches are used to monitor the liquid level and temperature in fluid systems.
Level switches must not be used in highly flammable or corrosive liquids.
The medium must not contain particles, particularly metallic particles, to prevent deposits on the float or between the float and
switching tube. If necessary, filter the medium.
Please note the technical data in the appendix for the specific intended use, existing material combinations, as well as temper-
ature limits.
WARNING
All device models are solely intended for industrial applications. They are not safety com-
ponents . The devices must not be used if failure or malfunction thereof jeopardises the
safety and health of persons.
Use in explosive areas is
prohibited .
1.2 Functionality
1.2.1 Liquid level monitoring
The measuring tube is located inside the tank. The level switches are located inside the measuring tube. These are activated by a
magnet inside the level switch float.
The contacts are locked onto a bent rail, spaced as specified in the purchase order.
1.2.2 Temperature monitor
Temperature is monitored via temperature sensor (Pt100) inside the sensor tube. Depending on the version, there are several
switching outputs combined with one analogue output (4 - 20 mA). The temperature is shown in the display.
Please note the technical data in the appendix.
1.3 Design types
The level switch is equipped with different switching and analogue outputs based on the configuration. The outputs are freely
programmable.
The level switch can be equipped with the following options:
OV Oval flange
G1 Adapter to G1" flange
Please refer to the type plate for your equipment configuration. In addition to the job number, this also contains the item num-
