Nivotester FTW325 Point Level Switches Endress+Hauser Nivotester FTW325 Point Level Switches feature an intrinsically safe signal circuit for connection to a conductive sensor. The compact housing is designed for easy series mounting on a standard DIN rail in the cabinet. These cost-effective switches for conductive liquids offer pluggable terminal blocks for easy wiring, line monitoring up to the sensor, and a configurable sensitivity range. The alarm relay can also be switched as a second level relay (SPDT). Endress+Hauser Nivotester FTW325 Point Level Switches have a measuring range of up to 200kΩ and an ambient temperature range of -20°C to +60°C. Applications include pump dry running protection, point level detection in tanks for liquids (also for hazardous areas), and overfill prevention for tanks with flammable or non-flammable water-polluting liquids.
