Product Name: Float Level Transmitter and Level Switches /Water Tank Level Indicator Model NO.: UQK Resolusion: 20mm, 10mm, 5mm Signal Type: 4~20mA Chain Level Transmitter, on-off Switch LCD: with Local Display or Explosion-Proof Type Mounting: Vertical or Horizontal Level Adjustable: This Function Can Be Choose When Order Floater Number: One Floater Have 2 Control Position Move up & Down Warranty Period: 1year Transportation: Shipping, Air Freight Export Markets: Global Trademark: U-ideal Transport Package: Wooden Case or Carton Specification: SGS Origin: Tianjin, China HS Code: 90261000 Product Description UQK-A Top Mounted Float LevelSwitchFunctions and workingprincipleUQK magnetic floater liquid level switches is widelyused in liquid level control and alarm in open and closed container in lines of industrial, civil architecture, water and sewage. Itis a safe, economic, reliable, using flexible level controller with variousfunctions.UQKtypelevelswitchesisconsistingofmagneticfloater, stable leader, reed switches, explosion isolation type wiring box and installing fittings. Magnetic floater moves with liquid levelupanddown,andthereedcontactorsintheleaderchangingonandoffswitchandoutput the signalaccordingly.Reed tube contactors changing on and off instantaneously, and match with relays, it can realize various high pressure and large current control. The read contactors is strictly sealed in glass which were filled with inactive gas, so the contactors won't generate spark when contactors on or off. It can control the liquid levelsafely.UQK type magnetic floater level switches have the following controltypes: a.High, High High level, b.low, low low level control and alarm Floater number: >=1pcs, one floater have two setpointsNormally open: When the reed switch in the magnetic area, it is closed; when out of the magnetic area, it is open (notwork).Normally close: When the reed switch in the magnetic area, it is open; when out of the magnetic area, it is closed (work).

The transducer sensed voltage is fed to the transmitter for conversion to a signal of 4-20 mA, which can be either processed through a display unit to give a digital indication, with or without alarm set points or employed for use with Process Indicator, PLC/DCS or Recorders. The 4~20mA signal can transmit in the scope of 0~3Km which overcome the defect that the resist value changing during the remote transmitting to digitalinstrument.Model selectionModelselectionofFloaterlevelswitchandleveltransmitterUQKA: Level Switch (mark switch quantity), Example:A2B: floater leveltransmitterAccuracy (transmitter)A5mmB10mmC20mmSignal(transmitter)LLCDHHartMaterialS4SS304-30-120ºC≤2.5MPaS6SS316-30-120ºC≤2.5MPaFPTFE-30-120ºC≤1.6MPaPPP-30-80ºC≤1.0MPastructure1Float ball diameter: 45mm.
