During work on and with the device, the required personal protective equipment must always be worn. Appropriate use The EL 2 is a sensor for point level detection. You can find detailed information about the area of application in chapter " Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.
That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfil this obligation by observing the environmental instructions in this manual: • Chapter " Packaging, transport and storage" • Chapter " Disposal" Conductive probe EL 2 •...

Measuring probe Plastic sleeve at the probe end or laterally mounted Inflowing medium If EL 2 is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount EL 2 at a position in the vessel where no disturbances, e.g. from filling openings, agitators, etc., can occur. This applies particularly to instrument versions with a longer probe.
