Page 7: Principle Of Operation
EL 3 is a point level sensor with partly insulated conductive electrode for level detection. EL 3 is very rugged and can be used in all areas of industrial process technology. The level switch can be used in conductive liquids such as e.g. water. - Page 8 Storage and transport temperature see chapter "Technical data - temperature Ambient conditions" • Relative moisture 20 … 85 % Lifting and carrying With instrument weights of more than 18 kg (39.68 lbs) suitable and approved equipment must be used for lifting and carrying.

Page 9: Mounting
To maintain the housing protection, make sure that the housing lid is closed during operation and locked, if necessary. Transport Do not hold EL 3 on its electrode rods. Particularly with long rod ver- sions, the sensor can be damaged by the weight of the instrument. Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. - Page 10 Measuring probe Plastic sleeve at the probe end or laterally mounted Inflowing medium If EL 3 is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount EL 3 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.
