Product Instruction
UHK liquid level float switches is composed of reed pipe, magnetic float and internal circuit, taking advantage of the floating ball with a magnetic component lifting with the level to drive the opening or closing of the offline and online location of the dry reed pipe.Through the internal circuit device outputs a set of continuously open to continuously closed ( SPDT ) passive contact ,the contacts can string directly into the AC contactor coil circuit which can control the AC contactor to close or open ( without the need for additional secondary circuit ) to control the water pump motor or other electrical equipment’s play or stop and to control the container’s level automatically.

Product Features
1. Long life span, stable and reliable operation, easy installation, almost no maintenance
2. Independent of mediums’ physical and chemical status.
3. Magnetic float ball level switch is applied in all kinds of bad medium environment with density ≥0.65g/cm³.
4. Available for interface detection of mediums with two different densities.
5. Anti-explosion design.
6. Upper limit and/or lower limit available.

Control principle




UHK magnetic float type level switch is made of different materials and can be used in almost all strong and weak corrosion-resistant mediums and non-corrosive mediums. It can be used to control the liquid level in the containers automatically for such industries as petroleum, chemical industry, natural gas and so on.
