- For level monitoring in lifting and pumping systems in hazardous areas (ATEX) as "simple electrical equipment" in accordance with EN 60079-11
The integrated switch is activated when the fill level increases. The built-in tipping weight guarantees that the float remains in place and does not float up. The NIVOSTOP PR2-EX remains in the fluid and switches even in the tightest of spaces.
The NIVOSTOP PR2-EX is a robust float switch with a sturdy neoprene cable, even for harsh operating conditions.
The plastics used dissipate electrostatic charges via the cables earth conductor.
Important: For use in ATEX-zones 0, 1 or 2, the use of an intrinsically safe safety barrier is mandatory (e.g. RAC 531 B or RDN11, see accessories).
