1. General Information :
1.1. Material Acceptance
DX-ECAS level switch is a capacitive level sensor for level measurement of conductive liquid, nonconductive liquid, granulated materials with
solid particles, adhesive and acid/basic liquids. When a material comes between electrode rod and tank wall, a capacitance change occurs and
when this change exceed adjustment threshold, contact output is delivered. Designed for difficult process conditions. Refrigerated models
can be manufactured for high temperature and pressure conditions. Calibrations of triggering point and relay operation range can be performed
by the user under workplace conditions. It can be connected horizontally or vertically.
1.2. Information about Areas of Use
Liquid tanks, food machines, cooling liquid tanks, shipping, glycol tanks, brine,
waste water tanks.
Oil tanks, CO2 liquid tanks, high temperature tanks, non-conductive liquids.
Grain stores, cement, sand feed, flour, milk powder, organic and plastic granule.
Sticky hot and high viscosity liquid, acid and chemical liquids.
Ambient Conditions: Relative Humidity: 0-98 %RH Ambient temperature: 60C (It is not used under -20 C)
1.3. Working Principle
Capacitance definition, assuming two parallel conductive plates are used;
Advantages:
Optionally high temperature-resistant
design.
Easy assembly and sensitivity
adjustment.
No need to clean.
Not affected by foam, liquid splash and
probe coating.
Can be mounted upside.

However, there are scarcely any sensor type which this definition can be pratically utilized.
Above Formula can no longer bi reliable especially when residual areas increase due to large
distance (d) (which is usually the case). Thus, measuring impedance for distance measurements
give more accurate results than capacitance measurement.
e
Impedance definition Z = R + jL + ( jC )-1

R is defined as real component and represent ambient conductivity.

Impedance is calculated by this definition
C=
jLw second component is defined as inductive reactance. This component is present even if we perform capacitive
measurement. However we neglect this. Since we evaluate results based on electrostatic properties of the environment,
no error will occur. Resulting impedance definition is Z= R + (jC )-1.
e
Measurement is made by charge transfer in our capacitive sensors. Total impedance is defined as Z = V / I.
I (current) I = Q/t
Q (Coulomb)
T (sec)
Capacitive reactance we desire to measure is (jC )-1. Meaning that charge and impedance have the same phase.
To summarize, charge transferred to medium is directly proportional with capacitive reactance.
For sensors manufactured as coaxial;

b: Outer screen radius
L: length

Excitation applied between 10KHz250KHz based on length for all our models. ( =2xpxf)
Linearity error that may be caused by conductivity component (R) effect is prevented by electronic
circuit design and mechanical design. Reduced to a level lower than 1ppm, acceptable as zero.

2. Installation :
2.1. General Notes :
The device installation is in 2014 / 34 / EU criteria to ensure the safety of atmosphere and people from explosions, must only be done by staff who
knows the safeguards.
Do not apply force to the instrument during the installation!
Do not use the Capacitive Level Switch with a greater pressure than recommended pressure.
Do not forget that instrument is precise, carry it carefully and prevent not to be damaged.
It should be guaranteed that there are not any magnetic particles.
The Max. working pesure should not be exceeded.
2.2. General Installation Stages
*Remove Capacitive Level Switch from the box carefully
*Check whether gasket is appropriate for fluid or not. If is not appropriate, contact with the producer.
*Then, apply below mentioned explanations according to structure of the design.
2.3. Special Notes
*Please ensure that there is no mechanical stress on the shaft following installation. Such case will cause slipping in thecharacteristic curve.
*Capacitive Level Switch must be placed upright or horizontal.

2.12. WARNING !!!
Please pay attention to following matters in order to operate your flow switch properly.
When connecting the switch to the tank
Connect with 20 degree angle.
Switch from 30 cm each other
do not connect close
Please keep away from magnetic materials
like iron board ; otherwise the
characteristics might be affected
Please do not dip cables
potting into liquids,otherwise
instulation problem may cause.
Do not fasten switch reversely ,
otherwise its characteristics
might be changed.
Please do not drop ,
otherwise the characteristics
might be changed.
Vibration might be caused instability.
Do not remove the plastic parts
of the bottom of the switch body ,
do not loosen.
Do not pull the cable strongly,
otherwise the characteristics
might be changed.
Do not fasten switch reversely ,
otherwise its characteristics
might be changed.
Do not connect the switch in reverse.
Their characteristics may vary.
Excess current , to be drawn as
a result of direct connection to motor,
may burn relay of switch
