ATEX directive compliance
The level indicators of the HGFT. series comply with Health and Safety Requirements intended in 94/9/EC ATEX European Directive (explosive atmospheres) for equipments in Group II, category 2GD. Level indicators have “kX” protection degree and can therefore be mounted in equipments protected by means of “immersion in liquid”, without lowering protection degree.
II 2 G D k T6 X, marked on the HGFT. level indicators, represents the identification according to the directive.
In more detail:
Ex: identification for explosion protection pursuant to ATEX directive 94/9/EC
II: equipment group II (places liable to be endangered by explosive atmospheres)
2: identification of the category
G: potentially explosive atmospheres through gases, vapors or mist
D: potentially explosive atmospheres through dust/air mixtures
kX: protection degree by means of immersion in liquid
IIB: materials group (only for HGFT.16)
T6: temperature class
Ambient and/or fluid temperature: -30 ÷ +80°C
Every product codes will be supplied with declaration of conformity to European Directives.
Accessories on request
Brass nut type
GH. for fitting to reservoirs with wall thickness smaller than 5 mm.
Technical data
An adequate tightening torque (see table) is recommended when screwing the oil level indicator, so as to guarantee optimal tightness without any deformation of the packing ring. Suggested tightening torque is the result of laboratory tests at ambient temperature (23°C) with indicator, packing ring and reservoir walls perfectly cleaned.
