Hazardous Gas, Vapour and Mist Environments: ATEX Zones 1 and 2. A good example of an ATEX Zone 1 or ATEX Zone 2 classified operation would be a chemical or petrochemical plant, where there is a heightened risk for explosion during the course of normal day to day operations.
Zone 2, 22 means that there is no hazardous material present, but if there is, it is for less than 10 hours a year and in low concentration.
The ATX 750-2 is approved for use in Zone 22 D (dust) 'H' Class environments. These environments contain dust that is potentially explosive, such as bakeries, flour mills, sugar and coffee processing areas. It is also suitable for standard hazardous dust such as asbestos. Certification is as follows: Class H, Zone 22, II 3 D Ex tD A22 IP64 T100. ITP ATEX2-22 with integrated weighing system with four load cells has a sturdy steel structure with stainless steel forks and stainless steel IP65 weight indicator ATEX Approved for Zone 2.22. The red led display with digit h. 20 mm ensures optimum visibility in all lighting conditions of the environment. ATEX Zone 22 Definition – What is Zone 22? A Zone 22 area is classified as an atmosphere where a mixture of air and flammable substances in the form of powder or dust is not likely to occur in normal operation, but if it does occur, will persist for a short period only. These are typically storage areas but can also be process areas. ATEX Installation Instructions: Zone 2/Zone 22 3 2) Description The Micro Motion 24.(A, C, or D) Transmitter is integrally mounted to a Micro Motion Coriolis Meter. The 24.(A, C, or D) integral mount transmitter system architecture consists of the following system: two circuit boards, PowerIO and BFCore, are encapsulated into a potting shell.
The hazardous area industry has been stuck in the past for decades by large manufacturing companies that wish their customers to believe there is no alternative to their long lead, heavy, very expensive and cumbersome Ex d flameproof enclosures for zone 2.
What they don’t tell you is that under the ATEX directive 60079-15, steel panel enclosure manufacturers such as indEx, can self-certify for zone 2, 22, and category 3 solutions.
Atex 2/22
Type “n” solutions were developed to allow quality industrial components for use in zone 2. That is where a hazardous area material is only present for short periods of time- typically because of a fault somewhere else in the plant area. This means that there is a wealth of solutions available to indEx customers for zone 2, 22 which are not only cost effective, time sensitive and weigh much less than conventional Ex d flameproof enclosures, they also look much better as well!
