Features: Float level Switches is a simple and convenient liquid level control device that doesnot require power and complex circuit. It have advantages such as smaller volumes and long working life compared to general mechanical switches. As long as the materials selection is correct in the designs, used with any liquid and pressure, temperature, and other property. It is widely used in shipbuilding industry, generators equipment, petrochemical industry, food industry, water treatments equipment, dyeing and finishings industry, and other field. Working principle: The liquid level sensor is mainlycomposed of magnetic spring Switches and a floatingsball. The floatingsball contains magnetic materials, and one and more magnetic spring switches is installed in a closed nonmagnetic metal and plastic tube. Key Feature Our liquid level sensor ensures precise measurement in demanding conditions. NotableCharacteristics This sensor is highly sensitive, corrosion resistant, and easy to set up, making it adaptable to various harsh environment.
