COMPUTER
THEORY
A pressure sensor is made up of a piezoresistor
Wheatstone bridge. ALARM
Fig. (1)
As shown in fig.2, the pressure is applied to the
diaphragm and passes through the silicon oil onto
the Wheatstone bridge.

When the liquid pressure acts directly on the front

face of diaphragm, the Wheatstone bridge will
creates a differential voltage. This voltage
difference will then be amplified to obtain a current
signal of 4-20mA. When this current output is P = qHH
connected to an analog meter, we can scale
P : Pressure
properly to read the level of the applied liquid in a
container or a vessel. H: The level of liquid
q : Pressure constant
The formula used here is: P= q x H

Where P is pressure, q is pressure constant and H Piezoresister

is the level of liquid in a container. Silicon oil

APPLICATIONS
Fig. (2)
1. EC1100 is a liquid measurement device which can
be used in a variety of environments, including water-
agitation environments.
2. EC1200 can withstand high temperature liquid envi-
ronment.
3. The Standard Flange Type, EC1210 can be used in
liquid & gas pressure measurement environments
(i.e., mildly corrosive environments).
4. EC1300~1320 type is suitable for measurement of
very deep water, such as measurement of reservoirs.
5. EC1500 is suitable for pressure measurement or con-
trol devices such as those found in hydraulic and
pneumatic machines.

INSTALLATION
1. The transducer with extension cable & types are
equipped with an electrical housing standing
vertically and with a screw-type of cap on top. EC1100 EC1300 EC1320

2. The flange type transducer is equipped with a

side mounted electrical housing.

3. A special type of cable is used in the transducer

with extension cable. Please note that this cable
comes with 3 multi-thread copper wire and a
breather capillary. Therefore, any bending of the
cable is not recommended. Otherwise, the
measurements will not be accurate.

4. It is recommended that you use EC1200, when

the pressure level measurement of solvent is
implemented.

5. Do not use liquid that will crystallize or solidify in

all of your pressure transducer.

6. All our pressure transducers are designed to

perform in an environment with temperature
equal to or less than 80BC (except EC1200). If
the desired operation temperature is more than
80?C, please consult with our business
representative.

7. The tank or vessel should not be vacuum or EC1110 EC1310

where no pressure can be applied to the tank or
vessel.

8. Handle the sensor probe with care. The sensor

probe is extremely delicate, any extra vibration
or shock will damage it.

9. Do not use high pressure jet of water to wash the

sensing diaphragm.

ADJUSTMENT (FOR ZERO-SPAN)

1 Adjust the trimmer "ZERO" while the tank is empty to SPAN

make sure the current output was expected to reach
4mA.
1 Adjust the trimmer "SPAN" while the tank is full to
make sure the current output was expected to reach
20mA.
1 Since Zero & Span adjustment were all done in the
factory before shipment, do not perform the above
adjustments unless it is really necessary.
