Product Description
LXBP-5 Eight Wheel Pavement Smoothness Meter

One. Summary
Eight Wheel Pavement Smoothness Meter is developed basing on remaining the advantages of LXBP-2 with the feedback from most customers according to "JTJ J059-95 Highway Roadbed Pavement on Site Test Regulation". On electronic technique, it adopts the most advanced foreign micro-computer processing and large scale integrated circuit technology, which improves the integration level, and increase the memory (512K), can do the continuous test of 919km and record all the data. It reduces the unnecessary connector and improves the reliability. It automatically calculates the distance, makes the record of every 1000 points, and calculates the result and displays it. Sampling interval 0.05m or 0.1m is optional (usually 0.1m). It installed the clock inside, can display and record automatically. It adopts LCD for the screen. And it adopts the 6V 7.2Ah colloid maintenance free batteries for replacing of the rational storage battery. On mechanical, it reduces the weight on the premise of ensuring the measuring precision, accuracy and frame rigidity to make it easy for transportation, installation. LXBP-5 is the most advanced road flatness measuring device, with the advantages of continuous measuring, automatic calculation, display and print the standard deviation. It can be provided the portable micro-meter and real-time monitoring software for doing the real-time data processing.

Two. Structure and principle
LXBP-5 is composed by mechanic and electronic parts. The electronic part is composed by displacement and distance transducer, and digital indicator. The digital indicator is connected to the displacement transducer (on the frame) and distance transducer (on the detecting wheel) by two electric cables.

(1) Mechanic part structure
Composed by  
  1. Traction part: composed by connect plug and pull rod, connected to the front axle by nut.
  2. Front axle 
  3. Wheels: eight
  4. Displacement transducer: non-contact capacitance type displacement measuring system
  5. Locking device
  6. Main frame: including flexible square tube, guiding structure, back frame
  7. Measuring wheel: composed by pressing spring, lifting structure, rubber wheels, and distance transducer 
  8. Rear axle
  9. Wheel frame
  10. Eight wheels road flatness testing machine and shock eliminator

    (2) Electronic part
The instrument is composed by high performance micro-processor, address locking memory device and 512K data storage.
Because of the single chip is designed according to the industry measuring environment requirement, so its anti-jamming capability is better than common micro-processor. The power is colloid maintenance free batteries. The output part is composed by printer and Chinese display device.
The panel and function:
  1. Power switch and reset switch
Power switch is on the left top corner of the panel.
The under is the reset switch.
  1. Connector assembly
There are two connectors on the left top of the panel; they are 7 cores (connecting to the box for displacement and displacement transducer) and nine pins (connected to 220V power).
  1. Printer: on the left down of the panel.
  2. Display: on the right top of the panel, 20*4 character type LCD Chinese display.
It will sample automatically. Road number, mileage number, pile number, road breadth number, sampling interval, the limit deviation value, progressive increase and decrease type of pile number, date and time, etc.
  1. 4*5 bit keyboard
On the right down of the panel, including function keys, cursor control keys, and numbers keys. The five function keys are start/stop, menu, print, cancel, enter;
The four cursor control keys;
Eleven numbers keys: 0-9, , and .
Three. Main technical parameters
1) Function and precision
Automatic measuring, calculation, print the standard deviation σ. Take sample interval is 0.1m, sample error <0.04mm. The error of repeat test under same condition is less than 0.1mm
Automatically calculate and print the single direction totalize value H (mm)
Automatically calculate and print the area of section curve and datum line graph
Automatically calculate and print the plus and minus over speed (K+, K-)
Automatically calculate and print detecting speed value (km/h)
2) Traction way and detecting speed
Manual or locomotive; the min. radius of turning circle is 5m, detecting speed not over 8km/h.
Working environment temperature-10ºC-+40ºC
PowerHigh performance battery, 6V 7.2Ah
Dimension4060*800*600, extension: 4060mm, shorten: 2650mm
WeightTotal 200kg, meter case 2kg
