The Nivotester FTL325N switch unit is used for point level detection in liquid tanks, is suitable for hazardous areas and can also be used for overfill protection of tanks containing toxic, flammable or non-flammable liquids. With two-point control and point level detection, it is perfectly suited to safety-related systems. When used together with Liquiphant with FEL56 or FEL58 electronic inserts, it complies with IEC 61508/IEC 61511 and meets SIL2 functional safety requirements.
Advantages
The Nivotester FTL325N can be connected to 1, 2 or 3 measuring elements (1, 2 or 3-channel device)
The intrinsically safe signal circuit reaches EEx ia level and can be used in hazardous areas
Online monitoring ensures functional safety up to SIL2
The DIN rail housing facilitates side-by-side installation on the standard rail of a switch box
Pluggable terminal module, simple wiring
The NAMUR interface complies with EN 50227 (DIN 19234; NAMUR) or IEC 60947-5-6, for connecting NAMUR sensors or electronic inserts
Application
The switch unit uses NAMUR input and can be rail-mounted or installed separately.
Ambient temperature: -20 to +50 °C (-4 to +122°F)
International explosion protection certification; suitable for overfill protection of tanks containing toxic, flammable or non-flammable liquids; suitable for marine use
