1. General Information :
1.1. Material Acceptance
Check that there is no damage on the packages during the transportation immediately after the material acceptance. If packages are
damaged, open the packages immediately and check whether products are affected or not, if there is any damage, send your
complaint report to the transporter company and its photocopy to the address of our company.
1.2. Information about Areas of Use
ECAS level switch is a capacitive level sensor for level measurement of conductive liquid, nonconductive liquid, granulated materials with
solid particles, adhesive and acid / base 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. Models with cooling apparatus 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.
Application Areas
Liquid tanks, food machines, cooling liquid tanks, shipping, glycol tanks, brine, waste water tanks.
Oil tanks, CO2 liquid tanks, high temperature tanks, low-conductive liquids.
Grain silo, cement silo, sand feed, dough, 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)

However, there are scarcely any sensor type which this definition
can be pratically utilized. Above Formula can no longer
is reliable especially when residual areas increase due to large
distance (d) (which is usually the case). Thus, measuring
impedance for distance measurements gives more accurate
results than capacitance measurement.

by conductivity component (R) effect is prevented by electronic
circuit design and mechanical design. Reduced to a level lower than
1ppm, acceptable as zero.

R is defined as real component and represent ambient conductivity.
Advantages :
Optionally high temperature-resistant

No need to clean.
Not affected by foam, liquid splash and
probe coating.

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;
a: Central electrode radius
b: Outer screen radius
L: length

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.
*Allocate valve certainly in the process connection while instrument is used.
*Allocate blowdown valve under bottom flange for blowdown.
*If instrument is mounted outside and if there is any danger of lightning or
excessive pressure, take preventive measures by taking necessary measures.
*In the operating conditions, Capacitive Level Switch may be hot according
to situation of fluid, in this case, do not touch the indicator, otherwise your skin is damaged.
*The grounding product must be done properly. (can be done outside or in housing)
2.4. Installation For Mechanical Connections

RlyLED: Relay active during normal operation; means operation continues during
calibration. Flashes continuously in normal operation mode if relay is
active and blinks in calibration mode. It is red colored.
PwrLED: Means there is no sensor failure during normal operation, and means
desired measurement values are saved in memory during calibration.
Operates by flashing. If light is continuous, it indicates failure. It is gren colored.
CAL - S Button: Used to acquire High Level-span-value during calibration.
CAL - Z Button: Used to acquire Low Level-zero-value during calibration.
TST Button: During normal operation, functions as Relay Test; during calibration,
performs saving to nonvolatile memory of Zero-Span, the values previously acquired
by S and Z button, function.
LVL - C Pot: Adjusts relay triggering point between Zero-Span values.
LVL - F Pot: Performs as fine tuning for triggering point. Adjustment field is equal
to +/- 5% of the point adjusted by C Pot (total 10%).
DIF Pot: Adjusts Release level of the relay activated by C/F Pot.
Highest adjustable value is equal to half (50%) of the operation region specified by
Z and S. Meaning that, when DIF Pot is at 100% and relay is pulled, the level to
release it shall be reduced as half of the total scale.

Indification and Calibtarion :
Electronic Unit with Cable:
Electronic unit and sensor component can be separated by a cable that protected against
exterior conditions for easy calibration on site. Thanks to the properties of cable, easy assembly
for user is possible without affecting capacitive measurement.

2.11. WARNING !!!
Please pay attention to following matters in order to operate your flow switch properly.
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.

Their characteristics may vary.
Vibration might be caused instability. Do not fasten switch reversely ,
otherwise its characteristics
might be changed.
Excess current , to be drawn as
a result of direct connection to motor,
may burn relay of switch
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.
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
