Mode Of Operation; Field Of Application; Serial Number Setup - Huba Control 713 Operating Instructions Manual

Construction
The level sensor consists of a ceramic measuring cell (relative and absolute
pressure) with an amplified electronic and is adjusted in the requested pressu-
re range. The sensor, the electronic and the connection cable are hermetically
encapsulated in a stainless steel case. The measuring diaphragm is protected
from outside influences by a protection cover. A venting pipe is included in the
connection cable with humidity protection element for the relative version. The
wide temperature range of the level sensor is compensated.

Mode of operation

The pressure of the medium acts on the keramic sensor which is deflected to
transmit the pressure to the piezo-resistive bridge in the measuring sensor.
The output signal of the sensor is fed to an electronic circuit which converts
it into a standard voltage and current output. The hydrostatic pressure which
is proportional to the submersion depth acts on the diaphragm of the sensor.
This pressure is compared with the atmospheric pressure (at relative pressure).

Field of application

The level sensor type 713 is generally used for hydrostatic level measurement.
All liquids specified in the data sheet are suitable for this sensor (no solids and
frozen media). For further media the user is responsible to check the compati-
bility with the parts in contact with the medium.
