Keep your container protected from hazardous overflow with this liquid-level sensor float switch from Sensata Cynergy3. As well as overflow, it'll also notify you if the container reaches low liquid levels when you’re emptying it. The sensor on the liquid surface uses magnetic force to signal for the switch to change when liquid levels rise or fall. You can mount this vertical switch to the top or bottom of your container.

• Up to 20 bar working pressure for high-pressure systems
• Made from robust and durable stainless steel
• Reversible NO (normally open) and NC (normally closed) switch action for flexibility with your electrical setup
• Uses DIN connector for standard installation and to ensure connection remains stable over time

This switch has a G1" BSP (British Standard Pipe) thread that lets you mount it externally. It’s ideal for use when access to the inside of your tank is restricted. You can also reverse the switch action to suit your application by simply removing the float from the stem, inverting it and then refitting it.
