DEKRA 12 ATEX 0063 X 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.
These transducers have marking code: II 1/2 G Ex d ma IIC T4...T6. 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). 05/2012 - 7312262200 - AD EX OPTISONIC 7300/8300 R02 www.krohne.com...
(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. www.krohne.com...

• die-casted stainless steel: -40...+55ºC 2.3 OPTISONIC 7300 C/...-Ex The OPTISONIC 7300 C/...-Ex ultrasonic compact gas flow meter is provided with the same electronics housing as the GFC 300 F/...-Ex and therefore has the same ambient temperature range of -40...+65°C (aluminum housing) and -40...55°C (stainless steel). The temperature classification table shows the relationship between the maximum process medium temperatures at a certain maximum ambient temperature.
The OPTISONIC 8000...-Ex high temperature (steam) flow sensor has an ambient temperature in the range of -40...+60°C. The maximum process medium temperature is listed in the table below.
