1.4 OPTISONIC 7300 C/...-Ex

The OPTISONIC 7300 C/...-Ex is the compact configuration of the GFC 300 ultrasonic flow converter and the OPTISONIC 7000 ultrasonic gas flow sensor. The gas flow sensor contains flameproof (Ex d) gas transducers made of titanium or flameproof (Ex d) transducers with a partly encapsulated (Ex ma) synthetic front. The gas flow converter is provided with non-Ex or intrinsically safe (Ex ia or Ex ib) signal outputs that are located in the terminal compartment,

which can either be configured as “Ex d” (flameproof enclosure) or “Ex e” (increased safety).

1.5 OPTISONIC 7000...-Ex

The OPTISONIC 7000...-Ex is the separate version of the ultrasonic flow sensor and has flameproof (Ex d) gas transducers. It is available in two versions, the normal version up to a

process temperature of 180°C and the extended temperature (XT) version up to a 220°C process

temperature.

The marking code can be:

1.6 OPTISONIC 8000...-Ex

The OPTISONIC 8000...-Ex high temperature (steam) flow sensor is for measuring (low and) high temperature gases including steam. The thermal sensitive parts of the transducer are located at a larger distance from the process medium inside the measuring tube. This meter is suitable for

process temperatures from -200°C up to +440°C.

The marking code is:

1.7 GFC 300 F/...-Ex

The GFC 300 F/...-Ex is the separate version of the ultrasonic flow converter and has flameproof protected connections to the flameproof gas transducers of the ultrasonic flow sensor. The ultrasonic gas flow converter is either provided with non-explosion protected or intrinsically safe

in-/outputs (“Ex ia” or “Ex ib”). The connection terminals of these in-/outputs are located in the terminal compartment, which is either configured as “Ex d” or “Ex e”.

1.8 Ultrasonic gas transducers

The OPTISONIC 7000...-Ex gas flow sensor, can be equipped with the ultrasonic gas transducers made of titanium (type G7.01 and G7.04) or with the gas transducers of type G5.nn and G6.nn (body: stainless steel, front part: epoxy compound).

The gas transducers of type G7.01 and G7.04 have type of protection “flameproof enclosure”

(Ex d) in accordance with EN 60079-1. The electrical connections are established in specially designed flameproof enclosures with a free volume well below 100 cm

Optionally the under KEMA 07 ATEX 0181 X approved gas transducers of type G5.nn and G6.nn

can be used. These gas transducers have types of protection “flameproof enclosure” (Ex d) in accordance with EN 60079-1 and “encapsulation” (Ex ma) conform to EN 60079-18.

These transducers have marking code: II 1/2 G Ex d ma IIC T4...T6.

II 2 G Ex de [ia] IIC T6 (PTB) II 2 (1) G Ex de [ia] IIC T6 (DEKRA)

The high temperature transducers (OPTISONIC 8000-Ex) are always flanged and have type of protection flameproof enclosure (Ex d).

See Chapter 2 for details on the temperature classification table(s).

INFORMATION!

Maximum ambient temperature applies to aluminum converter housing. Stainless steel

version is limited to +55

The ATEX-certificate KEMA 07 ATEX 0181 X (Issue no. 3) describes the maximum ambient temperatures of transducers type G5.nn and G6.nn, which should be read as process temperature (this is the temperature of the medium that surrounds the transducers). The ambient temperature is the (air) temperature at the location where the meter is installed.

1.10 Marking codes

Due to the various configuration options, the OPTISONIC 7300 gas flowmeter series can have several (different) explosion safety measures implemented.
