The PSE EX 16 family by SCHURTER has been extended to include the PSE EX 19 and PSE EX 22 mounting diameter. Furthermore, the certification of the PSE EX was enhanced and expanded. The PSE EX family is approved for use in potentially explosive atmospheres containing air and gases. Further application areas also include industrial sectors such as mills, where solids are found in smallest form as dust, which may be prone to self-ignition. Flammable substances such as gases, vapors or mist which are released into the environment, e.g. while in production, during transportation or storage, may ignite and pose serious consequences for persons and property. The same is true for dust which may develop in conjunction with air to an explosive atmosphere. To ensure security in these areas, the Device Directives 94/9/EC was developed for products and protection systems. The purpose of the guidelines is the protection of personnel and devices which are working in such hazardous areas. This is done by eliminating all possible sources of fire and ignitions in the products and systems used in these areas.
The PSE EX family is certified according to ATEX and IECEx regulations. The area of application is consistent with that of the device group II (other areas than mining). It comprises systems with a potentially explosive atmosphere consisting of a mixture of air and gases, vapors or mists or in industrial areas where dust-air blends infuse the atmosphere and the danger of a dust explosion can arise. The approval marking is Ex II 2 GD (according ATEX regulations), Ex ib IIC T6 ... T5 Gb and Ex ib IIIC T85 ° C ... T100 ° C Db (according IEC regulations) for gases and dust.
