Opening
Select the opening position
according to the medium, with gas
at the top and liquid and steam
at the side or bottom.
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, it can reduce the pressure impact
during the initial installation of pressure measurement.
Installation precautions
After the pressure in the pipeline stabilizes, slowly open the
stop valve to start measurement.
In the hydraulic system, pay attention to the upward installation
of the pressure interface of the equipment (for gas discharge).
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 tap hole is blocked, the pulse
buffer can be removed with a 2.5 hexagonal wrench, cleaned and then
reassembled（ Do not use hard objects to poke the pressure sensing
film inside the pressure hole during disassembly)
Try to install it in the place with small temperature gradient
change.
Warning!
The equipment must be installed without pressurization and power supply.
！
Install
Do not weld the base with pressure
transmitter! 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 to
be purchased separately)
PWarning!
Do not 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.
! 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;
During pressure measurement, pressurize and relieve pressure
slowly to avoid instantaneous increase to high pressure or decrease to
low pressure;
Please do not disassemble or touch the diaphragm when using, so
as not to damage the product.

Installation steps for connection with clamp or KF
The thread length of the
pressure transmitter must be
greater than the thread depth of
the base to ensure the effective
sealing of the end gasket.
The thread length of the
pressure transmitter must be
less than the thread depth of
the base to ensure effective
sealing of the root gasket.
Raw tape or sealant is used.
After locking, a small part of
the thread of the pressure
transmitter is surplus.
-Select appropriate sealing accessories according to the measured medium
and input pressure
-Put the seal into the installation position of the corresponding
connection
-Place the clamp connection or KF connection in the center with sealing
device
-Then lock the hoop
-Use a wrench to tighten the transmitter from the hexagonal nut at the
bottom of the transmitter to avoid directly turning the upper part of
the equipment and causing the disconnection of the connecting line.

Installation steps for threaded connections
-Select appropriate sealing accessories and sealing positions according
to the measured medium and input pressure
Installation steps for flange connection
-Select appropriate sealing accessories according to the measured
medium and input pressure(e.g. gasket)
-Place the seal between the equipment flange and the counter flange
-Install the equipment on the corresponding flange connection through
4-8 groups of bolts (according to the flange model)
Installation steps for connection of pagoda mouth or fast interface
-Check whether the size of air pipe and interface match
-After the air pipe is directly inserted into the interface, pull it
slightly by hand to check the reliability, that is, the connection is
completed
-Ensure that the sealing surface connected to the equipment is smooth
and flat

Represents a shielded wire, and all marked grounding points must
be effectively grounded. It is recommended to choose shielded twisted
pair signal cables. In order to avoid grounding circuits, the shielding
layer adopts single ended grounding, insulated floating grounding at
the pressure transmitter end, and grounded at the control cabinet end.
The transmitter casing is grounded by default, so it is required
that the on-site equipment be effectively grounded. If the on-site
equipment cannot be grounded, the indicated grounding point must be
effectively grounded.
