2.Product overview
CYYZ51 series pressure transmitter products use the OEM pressure sensor
which adopts stainless steel isolation diaphragm as the signal measuring
component, and are automatically measured by computer. The zero temperature
and sensitivity temperature compensation in a wide temperature range is
achieved through the laser resistor trimming process.The amplifier circuit
is fitted in a stainless casing, to convert the sensor signal into standard
output signal, which fully utilizes the technical advantages of the sensor.
As a result, the CYYZ51 series pressure transmitters have excellent
performances, which are strong anti-interference, overload protection and
shock resistance, low temperature drift, high stability, and high
measurement accuracy. It is the ideal pressure measuring device in
industrial automation field.
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 damage to the diaphragm, unpack and protect the cap
before starting the device. Please save the protective cap when the
product is shipped. Wear a protective cap on the pressure port
immediately after the device has been removed. Take extra care when
handling unprotected diaphragms, as unprotected diaphragms are very
sensitive and can be 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)
When installing, the pressure interface should be installed
upward (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.
