2.Product overview
CCY15 series differential pressure transmitter adopts compact structure,
high static pressure value, stability and reliability. The temperature
compensation of zero point and sensitivity in wide temperature range is
carried out by laser resistance adjustment technology after computer
automatic test. It has strong anti-interference, overload and impact
resistance, small temperature drift, high stability and high measurement
accuracy. Therefore, the product can be applied to various occasions for
differential pressure measurement, including harsh corrosive medium
environment. It is an ideal differential pressure measuring instrument in
the field of industrial automation.
3.Working principle
The pressure sensors diffuses a wheatstone electric bridge on
mono-crystalline silicon, and stressed by the measuring media (liquid or
gas)to cause change of the bridge wall resistance value(piezoresistive
effect). In result, a differential voltage signal will be generated, which
converts the signal corresponding to the range into standard analog
signal(as shown in Figure 3-1)or digital signal.

7.Installation and precautions
！
Warning!
a)
Installed without pressure nor power supply.
Warning!
！
b)
Transmitter should be installed by technician who read and
understood this operational manual.
Danger!
！
c)
The transmitter uses diffused silicon oil-filled core, which may
cause explosions if in-properly handled. Do not measure oxygen for sake
of he safety.
Danger!
！
d)
This product is not explosion-proof, using in explosive area may
cause serious injury and significant loss.
Warning!
！
e)
It is prohibited to measure media that is not compatible with
the transmitter.
f)
Please check if the package is in good order when receiving
the product, confirm the transmitter model and specifications.
! g)
No modification or change can be made to the device.
! h)
Handle with care, do not throw, do not force during
installation of transmitter.
i)
In order to ensure the safe and reliable operation of the
transmitter, it is recommended to install a three-valve group between the
measured point and the transmitter to ensure that the measured medium is
slowly and uniformly applied to the positive and negative pressure
chambers of the differential pressure transmitter.
j)
When installing, it is recommended to keep the pressure
interface at both ends horizontal so as to reduce the influence of the
installation position on the transmitter. If the size of the interface
does not match the size of the field interface, the self-made
conversion joint can be connected.
k)
It is recommended to install at minor temperature gradient variations zone.
l)
It is recommended to adopt lightning protection and over
voltage protection facility between power distribution box or power
supply and the transmitter, for the fact that there will be danger if
the transmitter is installed in a harsh area.
m)
While measuring steam or other high temperature media, please
ensure the media temperature is not higher than the maximum work
temperature of transmitter. If necessary, it is required to install a
cooling device.
n)
Install a pressure cutoff valve between the transmitter and
media, to inspect and avoid interference with measurement accuracy
caused by pressure port clogging.
! o)
This product is a light current device, it must be laid
separately from high current cables during wiring, and comply with
relevant national wiring standard (GB/T50312-2016）.
p)
Ensure that the power supply voltage meets the requirement
of the transmitter. And make sure the maximum voltage of the pressure
source is within the range of the transmitter.
q)
Increase pressure and reduce pressure very slowly during the
pressure measurement, to avoid instantaneous high voltage or low
voltage.
Warning!
！
r)
Make sure the pressure source and power are disconnected
before disassembling the transmitter, to avoid accidents in result of
media ejection.
s)
Do not disassemble during usage, and do not touch the diaphragm,
to avoid damage of the product.
