Included in delivery of the device:

•Brief instructions (Leporello)

•CD-ROM with detailed documentation

•Sealing plug(s) or sealing screw(s) for the process flanges(s)

1)For oxygen applications, add Order code E10.

2)Version 7MF4333-1DY... only up to max. span 200 mbar a (2.9 psi a).

3)When the manufacture’s certificate M (calibration certificate) has to be ordered for transmitters with diaphragm seals, it is recommended only to order this certificate exclusively with the diaphragm seals. The measuring accuracy of the total combination is certified here.

4)Whe the acceptance test certificate 3.1 for transmitters with direct-con- nected diaphragm seals is ordered, this certificate must also be ordered with the corresponding seals.

5)Not for span "5.3 ... 100 bar a (76.9 ... 1450 psi a)". Position of the top vent valve in the process flange (see dimensional drawing).

6)Not together with Electrical connection „Screwed gland Pg 13.5“ and „Han7D plug“.

7)Without cable gland, with blanking plug

8)With enclosed cable gland EEx ia and blanking plug

9)Not together with type of protection "Explosion-proof" and and type of protection "Ex nA".

10)Not together with types of protection "Explosion-proof" or "Intrinsic safety and explosion-proof"

E)Combinations of the versions marked with E) are subject to the export regulations AL: 2B230, ECCN: N.

F)Subject to export regulations AL: 9I999, ECCN: N.
