1 Introduction
MPM480 piezo-resistive pressure transmitter is designed by our
company, it adopts the advanced pressure transmitter technology, and
combine with our years of experiences on developing pressure
transmitters. Zero and Span output of MPM480 transmitter can be
precisely calibrated, it has compact size with good accuracy and
stability, and easy adjusting.
As for users’ various requirements, MPM480 pressure transmitter is
available with general version, Explosion-proof version and Ship-use
version.
In which, General version of MPM480 transmitter includes the types for
general use, Flush-diaphragm, Sanitary and Anti-corrosive
applications.
General version of MPM480 pressure transmitter has M20×1.5 or G1/2
male pressure port , it is widely applied for various pressure
measurements and process controls in the fields of petroleum,
chemi-industrial, metallurgy, electric power, light-industry, textile mill,
architecture, hydrography etc.
Flush-diaphragm of MPM480 pressure transmitter has M20×1.5 or “G
1/2” male pressure port , it is suitable for measuring the pressure in
2
food and medical applications, and possible attaching by the media.
Sanitary MPM480 pressure transmitter has a clamp flange connection
(DN25), it is suitable for pressure measurements in food, beverage,
medicine applications.
Anti-corrosive model MPM480 is made of anti-corrosive materials with
Tantalum isolated diaphragm, Hastelloy C housing and pressure
connection, viton O-ring sealing, thus it has good anticorrosion.

Two-wire MPM480 transmitter with plug connection can have a local
LCD or LED indicator to display current value or pressure value on site.
Explosion-proof version of MPM480 includes Intrinsically safe version
ExiaIICT6 and Flameproof version ExdIICT6, in accordance with
national standard GB3836.1-2010 <<Electrical Apparatus for explosive
gas atmospheres- Part 1:General requirements. >>
Flameproof model in accordance with GB3836.2-2010 <<Electrical
Apparatus for explosive gas atmospheres- Part 2: Flameproof
enclosure “d” >>Regulations, Explosion-proof marked with Exd II
CT6Gb.
Intrinsically safe version in accordance with GB3836.4-2010
<<Electrical apparatus for explosive gas atmospheres -Part 4: Intrinsic
safety “i” >>Regulations, Explosionproof marked with ExiaIICT6Ga.
Ship-use version of MPM480 pressure transmitter in accordance with
the related regulations of CHINA CLASSIFICATION SOCIETY (CCS),

3.2 Installation
3.2.1 Check before Installation
a) The measuring pressure is in the measurement range;
b) The measuring medium is compatible with construction;
c) The measuring medium would not jam the pressure-leading hole.
d) Explosion-proof transmitter must accord with the related regulation
in Part 15 of GB3836.15-2000 Electrical apparatus for explosive
gas atmospheres-Part 15: Electrical installations in hazardous
areas （other than mines）.
3.2.2 Installation Method
Generally, the transmitter shall be installed vertically upwards.
Use MPM480 pressure transmitter with flush diaphragm, the effective
depth of the internal thread should not be less than 15mm. Sanitary
MPM480 pressure transmitter using clamp installation.
Sanitary MPM480 pressure transmitter has a clamp connection.
The transmitter can be directly installed on a flange of the measuring
pipe, in order for easy installation or maintenance, it is recommended

3.3 Attenation
a) Don’t stab the pressure leading hole of the pressure port by any
sharp things, and do not touch the diaphragm by your fingers, it
may damage the sensor.
b) Flush-diaphragm transmitter and Sanitary transmitter always has a
plastic protection cover on the pressure port for avoiding any
possible damage on the diaphragm, please do not take it off until
installing the transmitter.
c) For flush-diaphragm version, do not try to use the sealing way of
twisting any sealing tape around the pressure port male of flush
diaphragm transmitter, it may affect the measuring stability or
damage the transmitter.
d) In case the transmitter is operating under thunder or lightning area,
please install an anti-thunder device in the circuits.
