Precautions for use
DANGER!
！
The transmitter adopts diffused silicon oil filled core,
and improper use will cause explosion accidents. To ensure
safety, it is strictly prohibited to measure oxygen.
！ DANGER!
This product is not explosion-proof, and its use in
explosion-proof area will cause serious personal injury
and material loss.

！ Warning!
It is forbidden to measure media with incompatible
materials in contact with the transmitter.
! No modifications or changes can be made on the
equipment.
! Handle with care and do not throw it at will. Please do
not use brute force when installing the transmitter.
When measuring steam or other high-temperature medium,
be careful not to let the medium temperature exceed the
working temperature of the transmitter. If necessary, a
cooling device shall be installed.
! This product belongs to weak current equipment, which
must be laid separately from strong current cables, and
shall be wired in accordance with relevant national wiring
standards (GB / t50312-2016).
Ensure that the power supply voltage meets the power
supply requirements of the transmitter. Ensure that the
high pressure of the pressure source is within the range
of the transmitter;
In the process of pressure measurement, pressurize and
relieve the pressure slowly to avoid instantaneous
increase to high pressure or decrease to low pressure;
Users should not disassemble or touch the diaphragm
when using it, so as not to damage the product.
Installation notes
Try to install it in the place with small temperature
gradient change.
The range range is less than 0.03mpa, and it is
installed vertically (except for special gas) to avoid
affecting the measurement accuracy. Others can be installed
on the measurement point at any angle.
It is recommended to install a pressure stop valve
before the pressure measuring point to facilitate the
maintenance and disassembly of the transmitter. In addition,
during the initial installation of pressure measurement,
it can reduce the pressure impact.
After the pressure in the pipeline stabilizes, slowly
open the stop valve to start measurement.

Warning!
The equipment must be installed without pressurization and
power supply.
In the hydraulic system, pay attention to the upward
installation of the pressure interface of the equipment
(convenient for gas discharge).
If the pressure interface is upward or lateral when
the transmitter is installed, ensure that no liquid flows
outside the transmitter shell, otherwise moisture and dirt
will block the atmospheric port near the electrical
connection and even cause equipment failure. Ensure that
the threaded connection edge of electrical connection is
free of dust and dirt residue.
If the transmitter is installed in a harsh site and will
encounter dangerous damage such as lightning stroke or
overvoltage, we recommend that the user carry out lightning
stroke and overvoltage protection between the distribution
box or power supply and the transmitter.
In order to avoid liquid flowing along the cable, causing
liquid accumulation at the waterproof joint or entering the
junction box, a U-shaped ring shall be configured between the
threading box and the pressure transmitter as shown in the
figure, and the bottom of the U-shaped shall be lower than
the pressure transmitter. It is considered that sufficient
length of electric cable shall be reserved for maintenance
and replacement.
A pulse buffer is installed inside the sensor. If the
liquid contains particles, the pressure hole may be blocked.
Installing the sensor in a vertical position can effectively
avoid the blockage of the pressure hole. After the pressure
hole is blocked, the pulse buffer can be removed and cleaned

It is forbidden to weld the
transmitter and the base together!
The deformation of the base caused
by welding shall be avoided, and
the waste slag shall be cleaned to
avoid scratching the measuring
diaphragm. (accessories need to be
purchased separately)
For high-temperature steam
measurement, it is recommended to
install a flexible buffer pipe
(zb02), and more than half of the
pipe cooling water (gas-liquid
temperature isolation) should be
injected into the cooling pipe in
advance. To ensure that the
temperature of the pressure
measuring point is controllable
Within the scope. (accessories need
to be purchased separately)
For the measurement of high-tem-
perature medium, a heat transfer
device, such as heat sink adapter
zb03, shall be installed between
the measuring pipe and the
measuring point to ensure that the
temperature of the pressure
measuring point is within the
controllable range.
(accessories need to be purchased
separately)
The thread length of the
pressure transmitter must be
greater than the thread
depth of the base to ensure
the effective sealing of the
Face seal end gasket.
The thread length of the
pressure transmitter must be
less than the thread depth
