This specific unit is designed for downgrading ATEX zones.
Its main use is to control extraction rates in ATEX zones.
Easy to use, this control unit is certified for use with specific flow sensors.
It must be installed in a safe area.
The two analogue inputs are designed to accept the following two configurations:
Two ATEX flow sensors for Zone 0.
Or
One flow sensor for Zone 0.
One explosimeter sensor for Zone 1.
This control unit is designed to detect a lack of flow and not for accurate flow measurement.
