Level limit switches with intrinsically safe signal circuit for connection to Liquiphant and Soliphant.
• Intrinsically safe signal circuits [EEx ia] for problem-free use in hazardous areas
• Highest functional SIL safety – fault-free PFM technology, line monitoring through to sensor, corrosion monitoring of tuning fork (Liquiphant)
• Compact housing for simple series installation on standard rails in switch cabinet
• Functional safety up to SIL3
Applications
Both the Nivotester FTL325P and FTL375P are ideal for level limit detection in tanks (liquids) and silos (bulk solids) and are ATEX certified for hazardous area use.
They offer liquid level detection in pipes for dry-run protection of pumps, overspill protection in tanks with combustible/non- combustible liquids harmful to water and offer two-point control and level limit detection using only one switching instrument.
