(15) Description
The Electromagnetic signal converter, types IFC 090 F-EEx, IFC 090 F/i-EEx,
MGC 090 F-EEx and MGC 090 F/i-EEx, when connected to a suitable certified flowmeter
primary head, is used for measuring, counting and displaying the linear flow of an
electrical conductive liquid. The signal converter unit supplies power to the field coils of a
remote primary head and processes the electrical measurement signal.
Within the flameproof signal converter housing various modules are fitted, some models
contain intrinsically safe circuits for connection to external circuits as specified below.
Ambient temperature range -20 °C ... +60 °C (for signal converter with electronics unit
type IFC090i).
Ambient temperature range -40 °C ... +60 °C (for signal converter with electronics unit type
IFC090).
The maximum surface temperature T85°C is based on an ambient temperature of 60°C.

Electrical data (continued)
The applicable type of explosion protection of the aforementioned intrinsically safe circuits
EEx is IIC is determined by the type of protection of the intrinsically safe circuit which is
connected to it, respectively EEx is 1113 or EEx ib 1IC or EEx ib 1113.
The aforementioned intrinsically safe circuits shall, from the safety point of view, be
considered to be connected to ground.
Installation instructions
For use in potentially explosive atmospheres of flammable gases, fluids or vapours:
The cable entry device shall be in type of protection flameproof enclosure"d"for the
terminal compartment in type of protection flameproof enclosure"d" or increased safety
"e"for the terminal compartment in type of protection increased safety"e", suitable for the
conditions of use and correctly installed.
For use in the presence of combustible dust:
The cable entry device shall be in type of equipment Category II 2 D, suitable for the
conditions of use and correctly installed.
Unused openings shall be closed with suitable certified closing elements.
With the use of conduit, a suitable certified sealing device such as a stopping box with
setting compound shall be provided immediately at the entrance to the flameproof
enclosure.
Routine tests
Routine tests according to EN 50018, Clause 16 are not required since the type test has
been made at a static pressure of four times the reference pressure.
Each signal converter shall withstand a test voltage according to EN 50019, Clause 6.1, of
500 V during one minute without breakdown between the field coils circuit and the
enclosure.
