1.8 Explanation of symbols
2 Application purpose
Electronic manometer for measuring over-pressure
and under-pressure of fluid and gas-like measuring
substances. The device is to be exclusively used for
the applications agreed between the manufacturer
and the user.
Explosion hazard area classification
The digital manometers ME01 are suitable for use
as 'Electrical equipment for use in areas with combustible gases', zone 2.
Designation as per guideline 2014/34/EU
II 3G Ex nA IIC T4
3 Product and function description
3.1 Design and mode of operation
A ceramic measuring cell acts as the pressure
transducer. The high resistance of the ceramic materials that are used allow use even for aggressive
media. There is a resistance measuring bridge attached to the side of the measuring diaphragm that
faces away from the medium. When pressure is exerted, the membrane distorts in the elastic range. t
the same time, the resistance values of the bridge
change proportionally to the measuring pressure.
These values are implemented and displayed by
the installed electronics. There are electrical uniform signals 0/4…20 mA and 0…10 V in a 3-wire
system available for remote transmission.

4 Installation and assembly
As standard, the device with the connecting port for
connection to pipes and other connection parts,
such as the welding sleeve, union nut with soldering
and welding nipples, is equipped with soldering and
welding nipples (see data sheet MZ...). It can be
mounted to a wall using the wall bracket (see data
sheet MZ...). Manometer screw connections for 10,
8, 6 mm dia. pipes can be supplied for connection
to pipes.The enclosure protection type IP 65 is only
guaranteed, if a suitable power supply cable is
used.
4.1 Process connection
• By authorized and qualified specialized person-
nel only.
• Only for the designated mechanical process
connection - for the model, see the order code
on the device type plate.
• The pipes need to be depressurized when the
device is being connected.
• Do not mount the device against existing water
columns, and secure suitably against pressure
surges.
• Use only with media suitable for operation.
• Observe the maximum pressure.
• Check that the pressure connections do not
leak before commissioning.
4.2 Electrical connection
• By authorized and qualified specialized person-
nel only.
• Disconnect the system from the mains before
connecting the device.
• Do not take out the connecting plug while ener-
gized
Explosion protection instructions
To guarantee safe operation of the instrument, the supply circuit must satisfy
the requirements for zone 2, category 3,
and the locally applicable regulations
and guidelines for the installation and operation of
electrical systems in explosion hazard areas (e.g.
EN 60079-0).
4.3 Wiring diagram
Do not take out the connecting plug
while energized
Static electricity
The case must be equipped with an
earth connection to reduce the surface
resistance.
5 Commissioning
• All electrical supply, operating and measuring
lines, and the pressure connections must have
been correctly installed before commissioning.
All supply lines are arranged so that there are
no mechanical forces acting on the device.
• If liquid measuring media are used the pressure
connection line must be vented, as liquid columns of different heights in the pipes can cause
measuring errors. The instrument must be protected against frost if water is used as a medium.
• The pressure sensing lines must be installed on
an incline so that no condensation pools can
form.
• The pressure sensing lines need to be kept as
short as possible and installed without sharp
bends to avoid interfering delay times.
• Appropriate shutoff valves must be provided to
ensure safety during installation, maintenance
and inspection
The supply voltage may not exceed 30 V DC. The
supply circuit must be protected by a slow 200 mA
fuse. Only a CE-compliant power supply unit may
be used as a power supply.
6 Maintenance
The instrument is maintenance-free.
We recommend checking the instrument at regular
intervals to ensure reliable operation and a long
service life.
• Inspecting the output signal.
• Check the leak-tightness of the pressure con-
nection lines.
• Check the electrical connection (cable clamp
connections).
The precise test cycles and operating and ambient
conditions need to be adjusted. If various instrument components interact, the operating instructions of all the other instruments also need to be
observed.
7 Transportation
The measuring device must be protected against
impacts. It may only be transported in packaging
specifically intended for transport.
8 Service
All defective or faulty devices should be sent directly to our repair department. We would ask you to
please coordinate all return shipments with our
sales department so that we can ensure careful
processing of all faulty devices for our customers.
Measuring residues in and on dismantled devices can be a hazard to people,
animals and the environment. Take adequate preventive measures. If required,
the devices must be cleaned thoroughly.
