The electrical circuitry of the transmitters is mounted inside a flameproof metal enclosure type RFT9739E and 9739MVD6*W. The RFT9739D, RFT9739R and 9739MVD6*Y are not flameproof enclosures. Amendment 3 to the ATEX Certificate DMT 02 ATEX E 051 X incorporates the new EN 60079 Series Standards and therefore the marking changed from EEx to Ex. Additionally this amendment includes the new electronics module for Field Mount Transmitters (9739MVD) and the redesigned Display Cover for use in Safe Areas only.
