• Special conditions for safe use:
- The equipment is an appliance that is intrinsically safe.
- It may be installed in potentially explosive atmospheres: areas 0, 1
or 2 and areas 20, 21 or 22.
- The connector only has to be connected to an appliance that has the
intrinsic safety certification. Said connections must be compatible
as regards intrinsic safety and comply with the following parameters.
- Ambient temperature for use: from 0 °C to +60 °C
• Special parameters of relevant protection method/s:
Ui ≤ 15V, Ii ≤ 50 mA, Pi ≤ 188 mW, Ci ≤ 1,2 nF, Li ≅ 0
• Mechanical assembly and fluid connections that are compatible with
said marking and said use:
Use only brass, stainless steel, aluminium or PVDF fittings.
If the fitting is fitted with a PP paddle-wheel, ensure there is no risk
of explosion within the pipe: the fluidics must be within the safe
area.
• Any other fittings are prohibited in explosive areas.

mines.
- It may be installed in potentially explosive atmospheres: mine.
- The connector only has to be connected to an appliance that has
the intrinsic safety certification. Said connections must be compa-
tible as regards intrinsic safety and comply with the following para-
meters.

• Mechanical assembly and fluid connections that are compatible with
said marking and said use:
- Use brass or stainless steel fittings only, with a PVDF paddle-wheel
for an S030 fitting.
- Any other fitting is prohibited.
- The appliance must be protected from mechanical damage. Mecha-
nical protection with order code 553519 should be used.
2.2. Warranty and liability
During the warranty period and outside said period the Bürkert company
alone is authorised to carry out repairs or alterations to any of its
products that has been awarded EC type examination certification.
Bürkert disclaims its liability in the event of non-compliance with this
clause.
The assembly work must be carried out by qualified personnel. In
the event of problems with installation or commissioning, please
contact your Bürkert supplier as soon as possible.

2.3. Precautions during installation and
commissioning
• Always ensure that the appliance that is in contact with the fluid to be
measured is chemically compatible.
• Similarly, when the equipment is cleaned please use products that
are chemically compatible with the materials of which the appliance is
made.
• Protect the device from electromagnetic perturbations, ultraviolet
radiations and, when installed outside, from the effects of climatic
conditions.
Said appliance must be installed in accordance with the provisions
of standard EN 60079-14: Electric appliance for potentially explosive
atmospheres.
Part 14: electrical installations in dangerous sites (other than
mines).
When the sensor is disassembled from the pipe, take all the precau-
tions associated with the process.

2.4. Traceability
The SE30 Ex products are identified by an individual batch number which
allows them to be traced. This number (5 figure), plus the year, is
inscribed on a nameplate bearing the complete reference for the
equipment.
This product is an appliance for potentially explosive atmospheres. In this
regard and in compliance with the EC ATEX 94/9 Directive, provisions
must be made to ensure ascending and descending traceability.
Our ATEX notified quality system ensures this traceability up to the initial
point of delivery.
Except as otherwise agreed in writing, anyone that guarantees to
redeliver said equipment undertakes to put in place a system that allows
for equipment that is not conform to be recalled if necessary.

3. Description
3.1. Construction and measurement principle
The flow sensor SE30 Ex is an electronic module which must be asso-
ciated to a measuring element, either a fitting S030 (brass, stainless steel
or PVDF) or a fitting S070.
Depending on its place of use the SE30 Ex sensor must be con-
nected according to the safety instructions – notice of ATEX
instructions.
The sensor detects the rotation of the paddle-wheel and modulates the
current of the supply line as per the Namur standard (0.5 mA or 2.5 mA).
The modulation frequency f is proportionate to the flow rate Q using the
formula f = K.Q.
f = frequency in Hz
K = factor K specific to each fitting, in pulse/l
Q = flow rate in l/s
In order to exploit this signal, connect a Namur type intrinsic safety barrier
to the SE30 Ex. It detects the modulation and converts it to a frequency
on its open collector output.
