LEEC SMP131-SLH205G2F24MD-5A Quick Installation Manual

！
Pressure sensor/ transmitter shall be installed by professional
engineers, technicians and other qualified personnel, please read carefully
the content and important information provided by this installation guide
and label before installation.
！ Pressure sensor / transmitter is powered by an external power supply,
the power supply should be in accordance with relevant standards
stipulated by energy limitation circuit, and pay attention to the high-voltage
that may exist in the circuit.
！
The static overpressure has been marked on the label, the maximum
pressure value should be no more than the span of transmitter.
！
Using pressure sensor/transmitter in dangerous situations, product
installation, using and maintenance should comply with installation guide
and relevant provisions of national standards.

For measuring high
temperature steam, should be
pre-injected in most tube
condenser cooling water,
waiting for the steam pipes is
stable, slowly open the shut-off
valve to start measuring.
Can be used to gauge and
absolute pressure
measurement, waiting for
the pressure vessel is
stable, slowly open the shut-
off valve to start measuring.
Can be used for liquid level
measurement in Open container,
should be considered media
compatibility, and mounted on a level
and temperature changes smoothly
position, it will help to improve the
measurement accuracy.
2pcs pressure transmitter can be
composed of DP measurement
systems, commonly used in the filter
control or closed container level
measurement.
For light weight pressure transmitter,
pressure transmitter does not need
the support bracket, can be mounted
directly on the pressure tube.
Using a spanner to wring hex ​ ​ b olts,
the maximum torque force is no more
than 50Nm.

The tapping location is selected by
measuring media, situated at the top for
gas, on the side or bottom for liquid and
steam.
！
Forbid base welding with pressure
transmitter! Avoid to the base
deformation caused by welding, and
pay attention to clean up waste residue,
avoid scratching the measuring
diaphragm.
The thread length must be more than the
base thread depth, to ensure end gasket
seal Is effective.
The thread length must be less than the
base thread depth, to ensure root gasket
seal Is effective.
Using raw material belts or sealant sealing,
when thread lock hard, there is a small part
of space.
