The capacitive levels indicators SCP 30 ATEX are to be used to control the maximum or minimum level of liquid like water, oil, chemical products, etc., in tanks or recipients or control the maximum or minimum level of bulk solids like feed, cereal, grain, etc., in silos or vessels for use in potentially explosive Dust atmospheres hazardous area.

These devices also control the flow of these materials in pipes or are to be used to detect conductive or non-conductive materials through non- conductive walls.

The output of the devices are protected against overloads and short- circuits. Due to the encapsulation of the controllers, the devices are inmune to noise or electrical interferences from mobiles, motors, etc.

When the level of product reaches the controller, the electronic unit reverses the signal due to a change of the capacity of the environment. When the product disappear from the detection range, the signal turns to the initial position.

The standard form is mounting the device with the mounting accesory Pg36 under request.

Drill a hole into the tank or silo wall, polish it, place the mounting accesory and introduce the device fixing it and fasten the nut of the mounting accesory to make sure of the tightness.

For a proper function of the device, a minimum of 10 mm of the head of the controller must be exposed to the material.

For use in potentially explosive Dust atmospheres hazardous areas the installation must be done according to the Standard and Normative documents.


Approximate measures given in mm.
