Product Description

UR type resistance liquid level probe and UQK-B level transmitter.
UR Type Resistance Liquid Level Probe-Magnetic Float Level Transmitter

1) The working principle of UR type resistance / Reed switch Contact Chain level transducer:  
UR type resistance liquid level probe can matches with magnetic Bi-color liquid level gauge realize remote indicating and control.
The UR resistance chain level transducer working principle is that:
The transducer consists of a float & guide tube assembly in non-magnetic material to achieve undisturbed flux. A chain of closely spaced glass encapsulated reed switches & a resistor is placed inside the tube. During rise and fall of liquid level, the float moves & actuates a reed switch in the chain, through a magnet system within it and develops a proportional voltage. The operation is similar to a sliding resistance potentiometer. If UQK-B type liquid level transmitter matched with intelligent digital display instrument, display instrument transmit the value of the UR type resist transducer to relative liquid level digit and LCD display the liquid level.
2) 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.
3) Technical parameter:
UR type: resist value 0~4kΩ;
UQK-B type: resist value 0~4kΩ, output current: 4~20mA, power supply: D.C24V two-wire system.
4) Calibration:
Connect D.C24V electric power when calibration and read current value through multifunction gauge.
Imitation calibration: using resistance box imitating UR transducer resist value.
4mA(zero location)calibration: resistance box resist value set to zero, then adjust UQK-B transmitter zero button, to read output current to 4mA.
20mA (full scale) calibration: adjust resistance box resist value to the value of UR type transducer's full scale. Adjust button "scale" to make transmitter output value read 20mA. At last repeat the zero and full scale, and then complete the task.
Practice calibration: UR transducer installed in magnetic floater liquid level gauge, UQK-B's transmitter installed in junction box of UR type, and correct wiring electric power and the digital electric current meters.
 4mA (zero location) calibration: set liquid location to zero, adjust UQK-B button "zero" to its outputting current read as 4mA.
20mA (full scale) calibration: set liquid location to full scale (whose full scale resist value is 4k), then adjust the button "Scale" to the digit when transmitter output 20mA, repeat the operation, the calibration has been completed.
