Capacitive levels

Intended use

Versatile model for normally horizontal or inclined mounting. The capacitive levels indicators L-E4S are to be used to control the maximum or minimum level of of liquids in deposits or tanks.

The model L-E4S has a Stainless Steel rod recovered of PTFE and the devices can have a shaft up to 2.000 mm length depending of the product to control.

It is not recommended for sticky liquids or products that have the tendency to settle over probe.

Function

The rod must to be exposed to the material. When the level of product reaches the rod, the control 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.

These devices have inside the housing a regulation system that allow the adjustment of the sensitivity due to a nut in the electronic module.

Mechanical connection

The device can be mounted horizontally or vertically depending on the model.

The normal installation is by screwing the device onto the deposit wall, with a mounting flange or with an appropiate support to fix it. For a proper function, the device should be installed with a 20 º to 30 º slope from the horizontal onto the silo wall to to facilitate the flow of the material and to prevent the material from remaining over the probe.

Dimensions

Approximate measures given in mm.
