The FTL325P switching unit is used for limit measurement in liquid tanks and bulk solids silos, is suitable for hazardous areas, and can also be used for liquid monitoring in pump suction pipes to prevent pump dry-running; suitable for overfill protection of tanks containing toxic flammable or non-flammable liquids; two-point control and limit detection with up to 3 measuring points connected; when used with Liquiphant with the FEL57 electronic insert, it complies with IEC 61508 and meets SIL3 functional safety requirements.
Advantages
Nivotester FTL325P can connect 1, 2 or 3 measuring elements (1-, 2- or 3-channel device)
Intrinsically safe signal circuit to EEx ia level, usable in hazardous areas
Online monitoring ensures functional safety up to SIL2, simplified WHG/SIL verification test at the push of a button
DIN rail housing for side-by-side installation on the standard rail of a switch box
Pluggable terminal module for simple wiring
Input, output and power supply signals electrically isolated from each other
Application
The control unit uses an intrinsically safe signal circuit for connecting liquid tuning forks or solid tuning forks.
Ambient temperature: -20 to +70 °C (-4 to +158°F)
International explosion protection certification, suitable for overfill protection of tanks containing toxic flammable or non-flammable liquids, suitable for marine use
