signal. The output signal changes in proportion with the level of the tank.
Applications
• Liquids.
•
Tanks, containers, wells, streaming water, drill holes, wastewater plants.
Pressure Equipment Directive (PED):
The units comply with the Pressure Equipment Directive and are designed
and manufactured for group 2 fluids in accordance with the sound
engineering practice. Use of group 1 fluids on request!

► In order to prevent or reduce oscillating movements of the unit:
unscrew the protective cap (A), screw the additional weight (order no.
E30402) to the unit.
The unit operates on the principle of relative pressure. A capillary tube ensures
pressure compensation. It is inserted through the connection cable.
►
Make sure that the capillary tube is not blocked. If necessary, install a filter
element (order no. E30400). Or use the splitter box with ventilation (order no.
E30401) for the electrical connection.
