Product Description

 Float Type Water Level Switch (A+E-75K-A)
OVERVIEW
The floating ball liquid level controller is composed of two parts which are not communicated with each other. When the measured liquid level changes, the floating ball changes, so that the end of the magnet swings. According to the principle of magnetic repulsion, the magnet reverse swing installed in the shell, the contact is switched on or off.
The floating ball liquid level switch is a liquid level controller which has the advantages of simple structure, convenient use, safety and reliability. The utility model has the advantages of high speed and long service life compared with the general mechanical switches, and the utility model has the advantages of strong shock resistance capability, and a product can realize multi-point control compared with an electronic switch. It has been widely used in shipbuilding, paper making, printing, generator equipment, petrochemical industry, food industry, water treatment, electrician, dye industry, hydraulic machinery and so on.
PRINCIPLE 
In sealed metal or plastic tube, magnetic reed switch design of one or more points, and then the tube through one or more hollow and filled with floating ring, ring magnet, and the use of fixed ring control, the floating ball and the magnetic reed switch in position, the floating ball floating in a certain in the range of upper and lower. The magnet in the floating ball is used to attract the contact of the magnetic reed switch, and the action of opening and closing is generated for the control or indication of the liquid level.

Product classification
1 stainless steel floating ball switch
General type stainless steel floating ball liquid level switch provides vertical and horizontal installation of two configurations, using 1 30VA or 100VA reed switch output which can level detection of relatively clean water, diluted chemicals and light oil reliably. Suitable media include deionized water and edible oil. The stainless steel liquid level sensor can be installed vertically in the storage tank or horizontally installed on the wall of the tank, which is used for high level or low level alarm
2 link floating ball liquid level switch

The connecting rod floating ball liquid level switch is capable of reliably detecting the liquid level of the relatively clean water, the diluted chemical solvent and the light oil, and the maximum range is 8 (2.44 meters). The 1-5 reed switch output, integrated container terminal box with integrated wiring terminal.
3 magnetic levitation ball liquid level switch
Float switches are often used in tank level control. No external power supply, side or top installation, wide temperature and pressure range, a variety of process connections, stainless steel liquid parts and explosion-proof design, a wide range of applications.
4 side floating ball switch
Magnetic side floating ball switch is often used in tank level control. Side mounted float switch is without external power supply, side or top of the installation, wide range of temperature and pressure, the process of a variety of connection, stainless steel connection part and the wet proof design makes it a universal float level switch.
5 cable floating ball liquid level switch
The float level switch is provided with two chambers, which are completely sealed by a special process in the process of processing the cable float switch. Different switch points can be adjusted by the balance hammer of the cable end. The utility model has the advantages of no toxicity and no mercury, and the utility model can be used for drinking water.
6 multipoint stainless steel floating ball switch
Floating ball switches are suitable for FM and CSA certified explosion-proof applications and general environmental applications. Float switch provides up to 4 switching points for PLC or SCADA remote device control. Multipoint stainless steel ball switches are typically used in high temperature and / or high pressure process tanks and require an explosion proof environment.
Type selection:
Float level switch switch includes adjustable float level switch and fixed float level switch, what we should be taken into account are the fixed or adjustable hysteresis, liquid density, installation position and process connection.
Usage:
Float type liquid level switch is used for liquid level detection, including all kinds of small and medium pressure and pressure of liquid storage tank, liquid level alarm indication signal to the remote site, can be applied to a variety of health, toxic, corrosive and explosive gases in dangerous places. There are a variety of installation, suitable for various forms of containers.
debugging
Float level switch only needs to be re calibrated before installation. Unable to adjust the switch itself. When using a multimeter measuring switch state, with the water level off in the waterline. This shows no problem. As long as the installation process and equipment to ensure that the water level of the same line. For example, SOR level switch, usually in the cylinder wall are close to the water line, we put the bubble in the switch in the sink, slowly sinking, causing the water to gradually close to the mark, the most close to the micro switch operation will hear voice.
Note: working temperature higher, inside liquid temperature higher; high temperature water density is less than room temperature density. Thus, the action line of the warm water is lower than the switch marked line.
The low level alarm is connected with the normally closed (NC), and the liquid level is high and normally open (NO). This kind of switch is not difficult to install. Liquid level switch itself will bring more than two pairs of micro switch, respectively, the output of the two pairs of normally open two pairs of normally closed contacts in the application is usually connected to the alarm".
Installation method
1 The types of float level controller A+E-75K-A and A+E-75K-B are connected the controlled container with non-standard flange, users should configure the corresponding installation flange (flanged B) (see the diagram)
2 The types of float level controller A+E-75K-A and A+E-75K-B are horizontal installation, the types of float level controller A+E-75K-C and A+E-75K-D are vertical installation (see below), (flange B) for controlled container (flange A) and non standard connections,  according to the corresponding configuration of the icon size, flange and controlled container connections, users should pay attention to the flange 6-M10 direction.
3 The float ball level controller(A+E-75K-B) is a scope adjustable level, the maximum range of 550mm. The method of adjusting the scope of action: to adjust the relative position of the upper and lower two positioning screws on the sector lever (to change the swing radius of the floating ball).
4 because the float ball diameter is larger than the diameter of the flange hole, when install the types of A+E-75K-C and A+E-75K-D, the covers of the two  type float ball liquid level controller should be removable;
The type of float level controller A+E-75K action range setting is adjusted, the standard maximum motion range is 2000mm; other length.can be customized

Attention:
- this type of controller is non waterproof structure, should not be used in outdoor occasions;
It should make the metal shell reliable grounding installation (usually connected to the flange), to ensure the safe use of electricity;
The controlled medium should not have magnetic impurities, and surface wave frequency can not be too large;
The use of instruments should be checked regularly;
The controller from the date of shipment is guaranteed for twelve months, the factory will take charge of all the product quality problems, quality problems, the factory is responsible for the timely repair or replacement.
