(15) Description
The Electro Magnetic Flowmeter Primary Head Series Optiflux 6000 F, sizes DN25 to DN80, is
used to convert the flow of a conducting fluid into an electrical signal. An associated flow
transmitter is used to supply the field coils of the primary head and to convert the measured
electrode signal into an output signal.
The flowmeter consists of a terminal compartment in type of protection increased safety "e", field
coils in type of protection "mb" and electrodes in type of protection intrinsic safety"i".
Ambient temperature range: -40 °C to +60 'C.
Minimum process temperature: -40 'C.
The relation between temperature class, maximum process temperature and ambient temperature
is shown in the following table:
Temperature Max. process temperature
class Ta <_40 °C 40 °C < Ta <_50 °C 50 °C <Ta <_60 °C
T6 75 °C 70 °C 65 °C
T5 95 °C 90 °C 85 °C
T4 130 °C 130 °C 130 °C
T3 180 °C 180 °C 170 °C
The maximum surface temperature "T 180 °C" is based on a maximum ambient temperature of
60 'C.
The enclosure provides a degree of protection of at least IP64 in accordance with EN 60529.
Electrical data
Field coil circuit .................................. U <_50 V(pulsed)
(terminals 7, 8 and 9) 1 <_125 mA(fuse protected)
Electrodes circuit (terminals 1, 2, 3 and 4):
in type of protection intrinsic safety EEx is IIC, only for connection to a certified intrinsically safe
circuit, with the following maximum values:
U; =20V; 1; = 175mA; C; = 0nF; Li = 0mH
The aforementioned intrinsically safe circuits shall, from the safety point of view, be considered to
be connected to ground.
Installation instructions
The cable glands and blanking elements shall be in type of protection increased safety "e",
suitable for the conditions of use and correctly installed. The devices shall provide a degree of
protection of at least IP64 according to EN 60529.
A cable, cable gland and blanking element with a continuous operating temperature of at least
85 °C shall be used for 40 °C < Ta <_50 °C and a process temperature >_150 °C and for
Ta > 50 °C and a process temperature >_110 'C.

(14) to EC-Type Examination Certificate KEMA 07ATEX0020 X Issue No. 1
Routine tests
Each flowmeter shall be subjected to the following routine tests:
- EN 60079-18, clause 9.1:
Visual check of the encapsulated parts. No visible damage of the compound shall be evident.
- EN 60079-7, clause 7.1 / EN 60079-18 clause 9.2:
A dielectric strength test shall be carried out between the field coil circuit and the enclosure and
between the field coil circuit and the intrinsically safe sensor circuit with a voltage of 500 V, during
1 minute without breakdown.
(16) Test Report
KEMA No. 2103459.
(17) Special conditions for safe use
The relation between temperature class, maximum surface temperature, maximum process
temperature and ambient temperature is as shown above in description (15).
The field coils must be protected by a 160 mA fuse. The breaking capacity of the fuse must be in
accordance with the prospective short circuit current of the supply.
(18) Essential Health and Safety Requirements
Assured by compliance with the standards listed at(9).
(19) Test documentation
As listed in Test Report No. 2103459.
