ALTOFLUX IFM x080 K-EEx and ALTOFLUX IFM x080 K / i-EEx

Primary head
The IFS 5000-EEx primary head of the IFM 5080 K/…-EEx compact flowmeter contains two
field coils above and below the measuring tube and two electrodes inside the ceramics
measuring tube on both sides. The field coils have type of protection increased safety "e"
according to EN 50019 and encapsulation "m" according to EN 50028. The electrodes are
provided with type of protection intrinsic safety "ib" according to EN 50020.

The primary head is available in meter sizes DN2.5 up to DN100. The IFC 090/…-EEx signal
converter (described in Sect. 1.4-1.5) is mounted on top of the primary head by four recessed
head screws of size M6 with internal hexagonal socket set.

Note:

The intrinsically safe electrode circuits of the IFM 5080K/…-EEx compact flowmeter are

only internal circuits and not accessible for the customer.
