Control of solids and liquids

Capacitive level indicators


Intendend use:

Model with threaded body and relay output.

The capacitive levels indicators SCP 3 D R 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. 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 immune 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. 

Mechanical connection:

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

Drill a Ø 30 mm hole into the tank or silo wall, polish it, place the device and fixing it with the nuts or screw it into a flange or into an appropiate support to fix it.

If the mounting is made with the mounting accesory, drill a G 1 " 1/4 hole into the tank or silo wall, fix the accesory and screw the device on it. Under request there are Galvanized or Stainless Steel G 1 " 1/4 nuts to fix the accesory to the interior of the wall as counter-nut. 


Approximate measures are given in mm.
