The ENICONTROL level indicators can be used in explosive II designated areas in accordance with VDE 0165.
Zone II |
covers areas, within which it is possible that a dangerous explosive atmosphere appears momentarily due to whirled up deposited dust. (excerpt from VDE 0165) |
The operational funds used in zone II do not require a special inspection certificate. The operational funds must be built so that neither explosive dust, air mixtures, or dangerous dust deposits can reach the inside. These conditions are fulfilled if the operational funds meet at least protection class IP 54. (excerpt from VDE 0165)
The ENICONTROL level indicator fulfills the conditions of the protection class IP 54. In addition, the installed micro switch meets the higher protection class IP 65.
