Specification
1.1 Intended use
The capacitive levels indicators L-E4 are to be used to control the
maximum or minimum level of liquid like water, oil, chemical
products, etc., in tanks or recipients and the capacitive levels
indicators L-E4S are to be used to control the maximum or
minimum level of bulk solids in silos or vessels.
These indicators have 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.
1.2
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.

2.1 Preparing for use
The rod must not to be struck by the filling stream.
For a proper function in side mountings, 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.
For a proper function, the device should be installed with a
distance of minimum 300 mm from the silo walls.
Read the Safety Instructions and the Operation Instructions
before using the controller.
stable deflector or protective cover. Also, this
protection roof or cover has to be installed in the detection of
minium levels in silos or vessels where heavy loads due to the
nature of the materials or the emptying system may damage the
rod.
Therefore the
bulk material stream should be directed or redirected accordingly,
or install a
L-E4 and L-E4S
