The MACView® EEx-d is also obtainable in explosionsafe form: the MACView®-EEx-d. In this design, the MACView® EEx-d may be placed in an environment with explosion risk.
For this purpose, EMS has got testing according to the latest ATEX specifications. The sensor is EEx-i tested for temperature class T4. The housing is designed in a combination of flameproof enclosure (EEx-d) and increased safety housing (EEx-e). All functionality built in the standard version of the MACView® EEx-d, is also implemented in the explosion safe version. For example, in the EEx-d version are also pushbuttons, in the increased safety housing, for controlling and adjusting.
EEx-proof
A probe is connected to the MACView® EEx-d, which can be used in area 0. This probe is proved EEx [ia] IIC T4 with ATEX certificate. The housing of the MACView® EEx-d is approved for use in explosion hazardous areas with proof of EEx-de IIC T6 according to CENELEC EN 50014, EN 50018, EN 50019 and EN 50020.
The MACView® EEx-d displays the measured values in ppm (parts per million) on the display. By this, these values are direct compareable with the MAC-value (Maximum Allowed Concentration). When this MAC-value is exceeded it is possible to act immediately.
