ATEX controllers
Control of liquids

Intended use

The pneumatic level controller is used to control 1 level in liquids at atmospheric pressure. Model certificated for use in potentially explosive Gas atmospheres hazardous areas.

Besides liquids can control fluid mixtures that allow the tube to be cleaned after the level of mixture downs.

The liquid or mixture that is controlled must not emit vapours that rarify the entrapped air inside the tube. This could be provoke a misfunction of the device.

Function

The controllers bases their function on the pneumatic outline. The controllers have an electric microswitch activated due to a membrane sensitive to pressure.

The action on the microswitch is carried out by the pressure of the air column entrapped inside the tube and the pressure chamber. Depending on the model, a water height of +100 mm WG is sufficient to trigger the switch.

Mechanical connection

Make a hole wide enough to introduce the tube or fix it with the mounting accesory usuable.

Ensure of the water-tightness of the unions. Do not use tow or Teflon tapes, only screw the tube to the housing up to the base gasket.

In lateral mounting, ensure of a minimum height of the tube of 200 mm minimum after the elbow.

Dimensions

Approximate measures given in mm.
