- Level control in open or closed vessels
- Alarm for excess or lack of liquid (leak detection, empty piping, dry-pump prevention, etc.)
- Fill or drain function with ES 2001 relay

The STE level probe with a relay ES2001 detect the level of electrically conductive liquids.
According to the model, up to 5 levels may be triggered (using the tank as the
reference electrode).
Provide a reference electrode if the tank is made of insulating material.
These STE probes are not suitable for liquids with hydrocarbons or grease or for any other application where an insulating layer may deposit on the electrode rods.
