Product Description Working principleThe UHK magnetic float level switch consists of a reed switch and a magnetic float. It is based on the buoyancy principle, using a floating ball with a magnetic component to drive the reed switch to open or close at each corresponding position in the measuring tube with the liquid level lifting, thereby realizing the detection and control of the position of the liquid level.The UHK magnetic float switch can be configured with up to 8 switches for 8-point detection. The magnetic float level switch operates without direct contact with the measured medium, the contacts are not mechanically worn, and can operate without an external power supply.Features1. No external power supply, passive output contact;2. Long life span, stable and reliable operation, easy installation, almost no maintenance 3. Independent of mediums' physical and chemical status. 4. Applicable for all kinds of bad medium environment with density ≥0.5g/cm3.5. Available for interface detection of mediums with two different densities. 6. Wide application range. Pressure 0~PN160 (max. up to PN320), temperature -40~+150 ° c; 7. At most 8 detecting points, delivering signal independently.8. Anti-explosion design.9. OEM Customization.ApplicationUHK magnetic float level switch and pontoon level switch are made of different materials, and can be used in almost all strong and weak corrosion-resistant mediums and none corrosive mediums. The magnetic float switch conditionSwitch condition in magnetic float level switch is normal open type, normal closed type, and transform type, which is defined as follows:Normally open type(SPST)---From the normal level,float rises or falls and when it passes the switch, the connection will close.Normally close type(SPST)---From the normal level,float rises or falls and when it passes the switch, the connection will switch offConversion type(SPDT)---When float passes the location of switch, the condition will convert.(Tubular type's standard configuration is conversion type)Measure for protecting contactor of magnetic level switchIn order to protect magnetic switch well, avoiding damage of contactor. User should take protecting measure as the following sketch.Technical ParameterSwitch point type:AO -- Normally open (250VAC 0.5A 20W ) SPSTAC -- Normally closed (250VAC 0.5A 20W ) SPSTC -- Conversion type (250VAC 1.0A 60W) SPDTNote: Voltage, current, power parameters are the maximum value. The switching voltage, switching current should not surpass switch wattage restriction.Maximum switch frequency<=1*109Switch error<=±8±2mmMin space between switches50mm(customize while space is less than 50mm)Transmitting distance>2000mWorking power supplyNo need of external power supplyMedium density>=0.5g/cm3Working pressurePN2.5~ PN160(Special for PN320)Working temperature-40~80 oC, -40~120 oC, -40~150 oC (others for customize )Float diameterФ30~Ф120(depending on pressure and density) Installation typeFlange: DN50~DN150 HG/T20592~20091-1/2'', 2'' external thread (downward install type)1/2'' external thread (upward install type)3/8'' external thread (upward install type)Installation angle<=±25°Electric interfaceM20×1.5 female threadIP gradeIP65\IP67Explosion-proof gradeExia II CT6Ga or Exd II CT6GbWiring box of switch Float ballmaterialFloat codeDi(mm)Do(mm)H(mm)Max O.P Press (PN)O.P.Temp(oC)Standard DensityCritical Density(g/cm3)1Cr18Ni9Ti316LV249242410-161501.00.8V289242810-161501.00.78V389382710-161501.00.55V4516455010-161501.00.6V5116516010-161501.00.5V75167575251501.00.55V12522125125251501.00.55V11016110110-18010-161501.00.8TitaniumT9516-2295110-18040-1601501.00.5T11016-22110110-18040-1601501.00.5PTFEF48224870-1006-161501.00.7PPP4824.54860-1206-20≤801.00.8P5824.55860-1206-201501.00.6P7624.57670-1206-161501.00.55Note:Float ball can be customized. Acceptable when density of medium is less than 0.5g/cm3.Titanium,PTFE,and PP material should be column float, the other is column or ball float.The form is for indication only. Manufacturer can change the size and structure of the float ball depending on operating differential pressure and density.
