The NIVA level controller MS1 EX is the ideal solution to control liquids with limited switching space in potentially explosive atmospheres classified Zone 0, 1 and 2. For example in:
The NIVA level controller MS 1 EX meets the latest requirements of EC directive 95/9/ EC (ATEX 95) and the international directive IECEx, which must be respected by applications in potentially explosive areas. In accordance with license ASEV 99.110036.02 the level controller MS 1 EX may be used in zone 0, zone 1 and zone 2 as well as in gas groups IIA, II B, and IIC, where an explosion hazard exists due to combustible materials in temperature classes T1 to T6.
For use in intrinsically safe electrical circuits in zones 0, 1 and 2 (Cl.1 Div.1).
