Mini float level switch, also known as the water level switch, suitable for water purification machines, water heaters, machinery, electronics, printing, chemicals, shipbuilding, test equipment, food machinery, humidifiers, washing machines, refrigeration and air conditioning, oil,, dehumidifiers , water dispensers, hydraulic machinery and other industries as well as some used in liquid level control of home appliances. Magnetic level sensor Features: stainless steel design, corrosion resistance, suitable for a variety of actions from the external environment, to meet customer application requirements normally open, normally closed option for custom, cable length and the terminal are free to choose (float switch mainly used for liquid level control, float with changes in the level of liquid rise and fall, float near the magnet and reed switch on and off to give them a high level signal to the circuit board, float The size, density, and the number of action points, the length of body can be made in accordance with the requirements of customers) 
 Mounting divided into: top mounted, bottom mounted, side installation. 
 Mounting thread common standard by our company: m10 coarse teeth, m12 rough teeth, 4 teeth, teeth 8 points, 1-inch teeth, 2-inch teeth, 1/8npt, flange to provide dn50-dn200, and aluminum, plastics, Explosion proof junction box, etc., for installation in various forms of containers, irrigation, water tanks, ponds, water tube. 
 Relationship between nature and float liquid medium: 
 1. Hydrometer is not the same time, the float will change the operating position, the general sg hours than water, float partially submerged in the liquid will be relatively increased. 
 2. Float switch reference to the proportion of product with water (sg = 1) it used to be considered in the selection of liquid level float proportion of sg, to be greater than the specifications indicate float, otherwise, the float switch does not float. 
 3. Viscosity of liquid does not dry up, the general should be used in large diameter stainless steel float. 
 4. Float switch is the use of magnets to sense the magnetic reed switch, so the measured level should be no iron, or iron filings stuck to float above the float float float would affect the team does not switch up the action. 

 Float switch and method of Ordering: 
 1. From outside the hexagon plane to the bottom of the float switch is the total length measurement for the switch. 
 2. In measuring the distance between the 2 retainer and float size, if the float is more than should be measurement of the distance between the float and the float. 
 3. Measuring rod diameter and thread type. 
 4. According to the control wiring and outlet water shall be marked with the needs of a few, long length of cable, wire material, float off in that position, the required voltage and current, electric shock in the form normally open or normally closed, temperature range and so on. 

 Float Selection Description: 
 Please follow the use of the measured object temperature, pressure, specific gravity, acid and other features, use the following variety of float. 
 1, temperature: pvdf float maximum temperature of 120 ℃, pp float up to 80 ℃, sus304/316 up to 200 ℃. 
 2, float size: pvdf float ф24 * 22 * ??9.5, has a plastic float size. Stainless steel float ф125 * 125 * 23, ф75 * 75 * 23, ф51 * 61 * 15, ф45 * 56 * 15, ф42 * 50 * 15, ф40 * 35 * 15, ф38 * 26.5 * 9.5, ф28 * 28 * 9.5 , ф24 * 24 * 9.5. 
 3, viscosity: should use larger diameter float, float a small proportion of liquid surface tension can be overcome. 
 4, resistance: the plastic material for acid-base concentration of acid sites, if any, consideration should be made of stainless steel 304/316 temperature material more resistant to high temperature. 
 5, Voltage: 50w/10w 200vdc/110vdc Current: 1.5a/0.7a. 

 Note: The float switch is divided into two types, one is less than 100vdc voltage low-power, there is a between that 100vdc-220vdc a high power. So customers you need to know how much voltage there is received, the Note: The connection voltage DC! . 
 Another: 
 a, the length determined by the user. 
 b, the control point can do one or more points. 
 c, control points can be on or off. 
 Note: 1, without prejudice to the principle of the original functions of products, the Company has the right to modify product appearance, color, size and internal structure, the product is subject to change without notice. 
 2, the product within the total tolerance of ± 2mm in length all is normal.
