2.Product overview

CYYZ61 series pressure transmitters adopt OEM pressure sensor with
stainless steel diaphragm as signal measuring element. After automatic
testing by computer, temperature compensation of zero point and sensitivity
in wide temperature range is carried out by laser resistance adjustment
technology. The amplification circuit is located in the stainless steel
case, which converts the sensor signal into standard output signal, giving
full play to the technical advantages of the sensor, so that the CYZ61
series pressure transmitter has excellent performance. It is easy to clean,
anti-interference, small temperature drift, high stability, and has high
measurement accuracy. It is an ideal pressure measuring instrument in
pharmaceutical, food and other industries.

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)
To avoid the damage of diaphragm, please unpack the package
and protective cap before starting the equipment. Please keep the
protective cap of the product. When the equipment is dismantled,
please put on a protective cap for the pressure interface immediately.
Be extra careful when handling unprotected diaphragms, because
unprotected diaphragms are very sensitive and easily damaged.
! h)
Handle with care, do not throw, do not force during
installation of transmitter.
i)
Vertical installation is applicable when pressure is below
0.03MPa (except for gas),to avoid affecting themeasurement accuracy.
Others can be installed at any angle. In case the interface size does not
match, it is allowed to make connecting adaptor.
j)
During installation, attention should be paid to the upward
installation of the pressure interface of the equipment (for gas
emission).
k)
If the pressure interface is upward or lateral when the
transmitter is installed, it is necessary to ensure that there is no
liquid flowing in the equipment shell, otherwise moisture and dirt
will block the air outlet near the electrical connection, or even
cause equipment failure. It is necessary to ensure that there is no
dust and dirt residue on the edge of threaded connection of electrical
connection.
l)
It is recommended to install at minor temperature gradient variations zone.
m)
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.
n)
While measuring 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.
o)
Install a pressure cutoff valve between the transmitter and
media, to inspect and avoid interference with measurement accuracy
caused by pressure port clogging.
p)
During the installation, use a wrench to tighten the transmitter
from the hexagonal nut at the bottom, to avoid wire disconnection caused
by direct rotation of the upper part of the device.
! q)
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）.
