Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Safety notes
2.2 Installation in hazardous area
SITRANS F M MAG 3100 sensor
14 Operating Instructions, 09/2012, A5E03005599-02
WARNING
Potential equalization
In operation, the output is earthed through the conductive medium being measured and
therefore potential equalisation is necessary throughout the hazardous area.
The apparatus housing shall be connected to the potential equalising conductor in the
hazardous area.
WARNING
External connections to Ex e terminals
The external connections to the Ex 'e' Terminals of the Remote version shall comply
with the following:
The wire conductors shall have a cross-sectional area between 0.5 mm2 and 2.5
mm2.
No more than one single or multiple strand wire conductor shall normally be
connected to each of the terminals. If multiple conductors are required, these shall be
joined in a suitable manner, e.g. two conductors into a single insulated crimped boot
lace ferrule.
The insulation on the wire conductors shall extend to within 1mm of the metal of the
terminal throat.
The terminal screws shall be tightened down with a torque between 0.5 Nm and 0.7
Nm.
The terminals shall never be exposed to temperatures outside of the range -50°C to
+ 130°C; in addition, they shall only be installed and wired with cable in an ambient
temperature of -10 to +80°C. Furthermore, in the event of there being a process
temperatures of + 180°C in conjunction with an upper ambient temperature of +50°C
the terminal strips should not be installed or wired with cable.
WARNING
Explosive gas or dust
The terminal box shall not be opened when an explosive gas or dust atmosphere may
be present.
WARNING
Do NOT open the device while energized; otherwise there is a risk of explosion.
WARNING
Laying of cables
Cable for use in zone 1 and 2 or 21 and 22 must satisfy the requirements for having a
proof voltage < AC 500 V applied between the conductor/ground, conductor/shield and
shield/ground.
Connect the devices that are operated in hazardous areas as per the stipulations
applicable in the country of operation, e.g. for Ex "d" and "nA", permanent cables must
be laid.

material, which makes the sensor highly resistant to a wide range of chemicals.
The present range of liner types includes:
● PTFE
● PFA
● Soft rubber
● EPDM
● Linatex
● Ebonite Hard Rubber
Electrodes are available in:
● Hastelloy C276 or C22
● AISI 316Ti (1.4571)
● Platinum / Iridium
● Titanium
● Tantalum
The sensors carry a wide range of approvals, see Technical data (Page 47).
