Samarium Cobalt Block Magnet

With the features of higher temperature and higher pressure, Sanlo Samarium Cobalt Block Magnet 5*70 works in water system level switch. Its shape is cylindrical, saturated magnetized and weighs 5G. Smooth surface without pits and it is long as normal type. As the most important accessory in floating ball components, magnets are magnetized according to customer needs and the direction of the magnets. There are S-grade and N-grade magnets, and different magnets are produced according to the assembly position of the product.

Product Feature

Sanlo Samarium Cobalt Block Magnet helps the liquid level gauge achieve water level control balance. When the magnetic levitation ball floats up and down along the pipeline with changes in the liquid level, the magnetic steel inside the levitation ball attracts the reed tube at the corresponding position in the sensor, causing a change in the total resistance (or voltage) of the sensor. Then, the transmitter converts the changed resistance (or voltage) signal into a 4-20mA current signal output. Our XMT series digital control instrument (or DSB type optical column digital display instrument) can be selected to measure the liquid level remotely, and upper and lower limit alarms can be set on the display instrument to achieve positional control of the liquid level.

Alternatively, other regulators can form a liquid level constant value adjustment system to achieve continuous PID adjustment of the liquid level.

In addition to the above-mentioned applications, samarium cobalt magnets can also be used in communication devices: in the field of communication, samarium cobalt magnets are applied in mobile communication, satellite communication and other fields, such as mobile phones, antennas, satellite receivers and other devices
