1.1General information ALTOFLUX IFS 4000 F-EEx
The ALTOFLUX IFS 4000 F-EEx electromagnetic primary head in remote design (F = field) complies with the European Directive 94/9 EC (ATEX 100a) and has been approved for hazardous classified locations of Zone 1 and 2 by the KEMA conform to the European Standards of the
EN 500xx series.
They have the following approval number:
KEMA 01 ATEX 2263 X
The IFS 4000 F-EEx primary head is designed for ambient temperatures in the range of -40°C up to +60°C inclusive. The IFS 4000 F-EEx primary head in remote design is connected to an associated signal converter, e.g. IFC 090 F/…-EEx, which is also approved in accordance with the European Directive 94/9 EC (ATEX 100a). The signal converter is installed on a distance from the IFS 4000 F- EEx primary head and connected via a field coil cable, an electrode cable and a bonding wire.
The IFS 4000 F-EEx primary head in remote design can be installed in environments that are classified as Zone 1 or Zone 2 hazardous locations. The maximum permissible process liquid temperature is dependent on the maximum ambient temperature (Ta) that can occur in that environment too.
For installation of the IFS 4000 F-EEx primary head please conform to the following listed three temperature classification tables on the next page. The first column lists the temperature classes for gases and the second one the rating for dusts.
The first table applies to meter sizes larger and equal to DN300, which have type of protection increased safety "EEx e".
The second table applies to meter sizes DN25 up to DN150 inclusive, which are performed as type of protection flameproof enclosure "EEx d".
The third table applies to meter sizes DN10-20 (type protection increased safety “EEx e” and encapsulation “EEx m”) and DN200-300 (increased safety “EEx e” and powder filling “EEx q”).
The following three tables only give the maximum possible temperatures for a lining material inside the measuring tube of the primary head that consists of PFA. For information on temperature restrictions of other lining materials, see Standard Installation and Operating Instructions.

IMPORTANT ! The maximum process liquid temperature values in the above listed tables only apply to a lining material of PFA (maximum operating temperature of 200°C). For other lining materials (e.g. rubber) is a lower process liquid temperature required for safe operation. See the standard Installation and Operating Instructions for detailed information about other lining materials.
The IFS 4000 F-EEx is marked with one of the following EEx-codes, which depends on the meter size range (see table below).
