Field of application
The Nivotester FTW325 is a point level switch with intrinsically safe signal circuit for connection to a conductive sensor. It has a compact housing for easy series mounting on a standard DIN rail in the cabinet.
For point level detection in tanks for liquids also for hazardous areas. Overfill prevention for tanks with flammable or non-flammable water-polluting liquids. Pump dry running protection.
Mounting: Standard rails in cabinet
Two-point control and point level detection
Ambient temperature: -20 to +60°C (-4 to +140°F)
International explosion protection certificates
