Thank you very much for selecting Micro Sensor’s product, please
take some time to read this operation manual very carefully before
using the product..
1 Introduction
MPM430 lower pressure transmitter is developed especially to measur
every lower pressure. It has good overpressure, good reliability, small
temperature drift, convenient installation and long-term stability.
The Explosion-proof version of MPM430 is an intrinsic safe version,
conforming the standard of GB3836.1-2010 and GB3836.4-2010.
Explode sign is ExiaIICT6Ga.

3.2 Installation
3.2.1 Attention before installation
a) Please be sure the measuring pressure will not exceed the
transmitter measurement range;
b) Please be sure the measuring media is compatible with the
construction material;
c) Please be sure the measuring media will not jam the liquid
leading hole.
3.2.2 Installation Method
Usually the transmitter should be mounted vertically up to the horizontal
direction. In order to install and maintain conveniently, it is recommended
to install a cut-off value between the transmitter and the measuring point.
3.2.3 The pressure port can be customized for users
according to special request.
4 Electric Connection
4.1 The transmitter could be connected with the external
circuit through socket, cable or connection box.
