Thanks for your using products from MICROSENSOR. To make the
most of this product, it is recommended that you carefully read this
manual before using it.
1 Introduction
1.1 Introduction
MDM7000 series smart differential pressure transmitters adopt
cutting-edge sensor technology for superior performance. They are
used to measure the level, density, pressure and flow of liquid, gas or
steam, convert the pressure signal into 4mA ～20mA DC analog
current signal output, and realize remote setting, monitoring and other
functions through communication equipment. They are applicable to
the demanding process chemical industry.
1.2 Quality assurance
a) The warranty period is specified in the quotation or specifically
stated in the contract by both parties. If a fault occurs during the
warranty period that is not due to user error, repairs will be free
of charge in principle.
b) After a fault occurs, the user can contact the distributor or Micro
Sensor. Please provide relevant information such as instrument
model and specifications, product nameplate information
(including ID), order information, fault description, and
environmental conditions so that the failure can be resolved
quickly and effectively.
c) For faults caused by the following reasons, the user shall bear
the repair costs even within the warranty period:
The instrument installation site does not meet the
environmental conditions described in Chapter 4, Section 4.1
of this manual.
2
Incorrect installation, incorrect operation, or incorrect repairs
by unauthorized body.
The on-site pressure exceeds the maximum operating
pressure of the instrument.
Damages caused by irresistible incidents, such as
earthquake, fire, war, etc.
2 Precautions for use
a) The pressure transmitter should be installed, debugged, and
maintained by professional engineers or technical personnel.
Before installation, carefully read this manual, understand, and
adhere to its various regulations.
b) The pressure transmitter is powered by an external power
supply, and the power supply circuit should comply with the
energy-limiting circuit specified by relevant standards, while also
being mindful of the potential presence of high voltage in the
circuit.
c) When using the pressure transmitter in hazardous environments,
installation, operation, and maintenance should adhere to the
relevant regulations in this manual and national standards.
d) Disassembly of the instrument is only permitted under
atmospheric pressure.
The manual employs several symbols to provide specific
information, which are explained as follows:
Warning
Indicates danger, which may result in serious personal accidents or
significant property damage.
3
Caution
Indicates general faults that may result in minor personal injury or
some property damage.
Prompt
Important information about the product, or a certain part of the
manual needs prompting.
Disclaimer
We have conducted checks to ensure the consistency between the
content in the printed materials and the hardware and software.
However, the possibility of discrepancies cannot be ruled out,
therefore, we do not guarantee full consistency between the
content in the printed materials and the hardware and software.
The data in the printed materials has been verified according to
regulations, and necessary calibration will be included in the next
version.

3 Specifications
3.1 Transmitter nameplate：
*Note 1: The nameplate certification is primarily based on the selection
results, and the nameplate specifications are for illustrative purposes
only.
*Note 2: When it is a differential pressure transmitter, the maximum
operating pressure becomes the maximum static pressure: 420bar.

4.1.4 Installation position
a) Please endeavor to minimize variations in temperature or the
existence of apparent thermal gradients. If the equipment in this
location is exposed to heat radiation, take insulation and
ventilation measures.
7
b) Avoid installing the transmitter in corrosive conditions. If
unavoidable, ventilation measures must be taken, and
precautions should be in place to prevent rainwater from
penetrating the cable.
c) Although the transmitter is designed with shock and vibration
resistance, caution should still be taken to avoid mechanical
disturbances that could cause damage to the pressure
transmitter.
4.2 Installation
The transmitter housing can be rotated approximately 300° relative to
the sensor (see outline construction and overall dimensions), allowing
it to be fixed in any position without affecting performance and internal
wiring. When rotating the housing, it is imperative not to forcibly
rotate the sensor part. Instead, use a 2mm hex wrench to loosen the
fixing screws by approximately one turn (taking care not to fully
unscrew them, as indicated in outline construction and overall
dimensions). Once the installation position is confirmed, tighten the
screws again. This method minimizes the impact on electronic circuit
connections and output displays. Installation as shown in the following:
4.2.1 Outline Construction and overall dimensions
Unit: mm
Warning
It is recommended to avoid installing in areas with large
temperature differentials, prone to condensation, susceptible to icing, and
high levels of vibration.
