Product Description

UQK-A Top Mounted Float Level Switch

Functions and working principle

  1. UQK magnetic floater liquid level switches is widely used in liquid level control and alarm in open and closed container in lines of industrial, civil architecture, water and sewage. It is a safe, economic, reliable, using flexible level controller with various functions.
  2. UQK type level switches is consisting of magnetic floater, stable leader, reed switches, explosion isolation type wiring box and installing fittings. Magnetic floater moves with  liquid   level up and down, and the reed contactors in the leader changing on and off switch and output  the signal accordingly.
  3. 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 level safely.
  4. UQK type magnetic floater level switches have the following control types:     a.High, High High level,  b. low, low low level control and alarm
  5. Floater number: >=1pcs, one floater have two set points
Normally open: When the reed switch in the magnetic area, it is closed; when out of the magnetic area, it is open (not work).
Normally close: When the reed switch in the magnetic area, it is open; when out of the magnetic area, it is closed (work). See to picture bellow:Level Control and Alarming-Switch Warning Water Float Level Switches

UQK-B resistance and 4~20mA liquid level transmitter
UQK-B type liquid level transmitter comprises of a level transducer and a transmitter. 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 digital instrument.
