The MLA1000 conductivity meter has once again been officially certified as suitable for use in potentially explosive atmospheres with IECEx certification. With this international certificate in accordance with the standards of the Electromechanical Commission, national certificates can now be issued more easily. The MLA1000 already had the important ATEX certification for the German market.
For quality reasons, the conductivity in oil is often kept in the lowest measuring range of 5 - 2,000 pS/m (picoSiemens/meter). Continuous monitoring of this important safety parameter is essential for industrial handling. The conductivity value of kerosene in a pipeline is set accordingly precisely and continuously maintained at this value by the MLA1000. The measuring device uses the flow velocity within the pipeline to provide a highly accurate current value of conductivity and temperature. Additives are added to prevent electrostatic charging, sparking and possible explosions. With the help of the MLA1000, these additions can be controlled extremely precisely and according to the principle of "as much as necessary, as little as possible". This is safer, more environmentally friendly and, last but not least, saves costs.
IECEx is the international procedure for the certification of electrical devices used in hazardous areas (Ex devices). Hazardous areas are divided into different classes and defined as areas in which explosive gas or dust atmospheres may occur. The IECEx Scheme under the auspices of the IEC (International Electrotechnical Commission) ensures the harmonization of standards. This means that the same standards, tests and test marks for explosion-protected devices are recognized worldwide without further ado. The assessment and test reports (ExTRs) are also mutually recognized.
