Adopting gaskets roots sealing,
the thread length should be less than
the base length(L1<L2); adopting
gaskets end face sealing, the thread
length should be more than the base
length(L1<L2)
Movable thread
Matched movable thread can
realize insertion length adjustment and
low-intensity seal.
Tri-clamp
Usually choosing gaskets with
material of PTFE, silicon rubber and
FKM which conform to hygienic
standards
Flange
Choosing gaskets according to
medium features and temperature range
and lock evenly.
Taper thread
Sealing with teflon tape or sealant
glue. When thread lock hard, there is a
small part of space
！Hygienic process connection Tri-clamp is approved by 3-A
hygienic certificate.
The gaskets of tri-clamp and all the wetted parts comform
with FDA standards.

The axis of protection tube and vertical
pipeline should be consistent. Contact
media reversely and the insertion length
should be half of the pipe diameter at
least.
！Angle of inclination: 45- 90°
The protection tube should be inserted
with enough length to avoid error
caused by temperature stratification.
Install at side of container
The protection tube should be inserted
with enough length to avoid error
caused by contacting the wall of
container.
Protection tube should contact media
obliquely and reversely, the insertion
depth should be half of the pipe
diameter at least.
Light-weight pressure transmitter
can be mounted directly on the
pressure leading tube. Bracket is not
needed.

EMC statement
EMC equipment instructions 2014/30/EU.
CE mark suggests the instruments are in line with EU standards
Users need to ensure the whole equipment conform to all the
applicable standards.
Depot repair
Please finish the following steps before the depot repair:
Removal of all the residues which would be harmful to human
health, such as inflammable, poisonous, cancerigenic and
radioactive substances.
Warning! Do not return the instruments if can not ensure the
dangerous residues are removed, eg: the dangerous residues
permeate into cracks or spread to the plastic.
！
Discard disposal
The instrument is not restrained of WEEE instruction 2002/96/EG
and laws of relevant countries.
Please pass the instrument to specialized recycling companies
other than local recycling points.
Retransport
Keep clean of the temperature transmitter. Stay away from any
Please adopt proper package to avoid damage in transportation.
dangerous medium!
Power supply
Independent linear direct-current power supply is suggested to be adopted for
the power supply of temperature transmitter, over large resistive load will result
in a large pressure drop, so it requires to calculate the all-in resistance of
signal cable, display meter and other record and display equipment, to ensure
the voltage provided to the temperature transmitter accord with normal
operating requirements.
Standard current signal output: 12-30VDC,
1~5VDC voltage output: 12-30VDC.
Grounding
Using cable with shielded twisted-pair signal has the best effect. To avoid
ground loop, shielded layer adopts single-end grounded.
Transient resistance built-in module is effective only in the case of good
grounding. Metal shell and internal grounding terminals are used to the nearest
Measurement signal is abnormal which should judge the process pressure is
abnormal, measuring system error or influence of installation environment or
abnormal in the pressure transmitter, then analyze the reason and take
corresponding measures.

pressure transmitter, it needs to check the power supply voltage, wiring, power
consumption and load resistance whether they meet normal operating
requirements. Also need to check if there is leaks and pressure impulse line
blockage, shut-off valve not turned on, etc.
Signal output error is too big or it exceeds need to checkthe normal range,
the power supply voltage, power consumption and load resistance whether
they meet normal operating requirements, the measuring range setting, if
adjustment is correct. Also need to check if there is leaks and pressure impulse
line blockage, shut-off valve not turned on, rapid temperature fluctuations, etc.
