A cable float switch is an automatic control device used to turn pumps, motors, and magnetic valves on or off. It can also serve as an alarm for specific pre-determined liquid levels. Designed for use with non-flammable liquids at 250 volts, this switch is ideal for a variety of applications. In potentially explosive environments, such as oil tanks, the float switch can be paired with (Ex) I-isolator switch units for added safety. The large float casing provides optimal buoyancy, ensuring reliable and smooth operation in all conditions. Featuring a double-chamber design and a final remolding finish, the switch is completely hermetic, offering long-lasting durability and protection.
Features:
- It can test the pressure of the liquid
- The float switch is a switch that regulates fluid level in the tank or well etc
- The float switch is resistant to water(sewage water) it is relatively capable of being used for oil, most acids and alkalis
- The float switch is not explosion-proof
