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

• Cost-effective point level switch for conductive liquids
• Intrinsically safe signal circuit EEx ia IIC for using sensors in hazardous areas
• Line monitoring up to the sensor
• Configurable sensitivity range
• Alarm relay can be switched as second level relay (SPDT)
• Easy wiring thanks to pluggable terminal blocks
