Stop dangerous overflow in your liquid tank with this level switch from Sensata Cynergy3. It uses a sensor to monitor changing levels of liquid in your container. It also notifies you when low levels are reached, so you can use it when emptying as well as filling tanks. The switch flicks position when the sensor that floats on the surface of the liquid detects rising or falling levels. It’s a vertical switch that can be installed on the top or bottom of tanks where there's no side access.

• Stainless-steel 316L body material is strong and resistant to heat and corrosion for increased durability
• Compact design means you can install it in small spaces
• Wide operating temperature range of -20°C to +120°C makes it suitable for use in tough conditions

This switch has a 1/8" British Standard Pipe (BSP) thread that allows you to install it internally. It’s best used with tanks that have ready access to the inside. You can reverse the switch action to suit the tank in use by removing the float from the stem, inverting it and then refitting it.
