3.3 Approvals
When using radar sensors in Ex and StEx-
areas or on ships the instruments must be
suitable and approved for these explosion
zones and applications. The suitability is
checked by the approval authorities and is
certified in approval documents.
VEGAPULS 56 radar sensors are approved for
Ex-zone 1 and zone 0.
Please note the attached approval documents
(yellow binder) when you want to use a sensor
in Ex-area.

Technical data
Ex-area zone 0/zone 1
Series 50 sensors require for use in Ex-areas
special safety barriers or separators providing
intrinsically safe (ia) circuits.
Following a choice of instruments with which
VEGAPULS 56 sensors work reliably. In
conjunction with safety barriers the resistor of
the signal line and the separator resistor
(separator voltage loss) must not exceed the
max. load (see load diagram in chapter
"3.1 Data“).
