LXBP-5C Intelligent Eight Wheel Flatness Meter

Product Information

This intelligent eight wheel flatness meter adopts a tablet computer as the main controller. The new flatness meter has made breakthrough improvements in the volume, usability, and software functions of the control system. Not only does it have more powerful data storage and revolutionary report management functions, but it also has data remote transmission (cloud storage) capabilities, making the product comprehensively ahead of similar products on the market.

The wireless data collector installed on the host body samples the deformation data of the displacement sensor at fixed distance intervals and sends it to the tablet computer. Record, calculate, store, and generate related reports of data using a tablet computer.

The wireless data collector is powered by 4 dry batteries and can be used continuously for 5-10 hours, completing measurements ranging from approximately 50Km to 100km. And the data collection is equipped with a small LCD screen, which can display the current displacement and measured mileage, with offline communication and battery undervoltage indication. Compact in size, it can be removed from the body when not in use. The wireless data collector and tablet computer use Wi Fi communication. The collector works in AP mode (wireless router) and is actively connected to the collector by the tablet computer. Compared with the original transceiver working in the ISM public frequency band, Wi Fi communication can increase the communication distance to 50m and the error rate is only one ten thousandth of the original product, greatly improving communication reliability. Unlike the previous generation of products, now even in cars with insulation film, there is no need for an additional omnidirectional antenna to use it normally.

The main controller is replaced by an 8-inch Win10 tablet without a bulky control box, greatly improving portability. And, as there is no need to use a car power supply, the tablet's battery supports at least 4 hours of continuous measurement (with the screen fully lit).

The flatness test software on the Win10 platform has been completely rewritten, with real-time curve displays for displacement deformation and road surface flatness, as well as various states, instantaneous values, and more. The software's usability and functionality far exceed those of the previous generation system. And the interface is beautiful, clear, and easy to use. The internal data storage adopts ACCESS database, with no upper limit on the number of records stored. In addition, a comprehensive data management system supports users to perform fuzzy queries based on numbers, project names, time, etc. Innovative report function, displaying all experimental measurements and calculations in the form of a curve graph, supporting report printing and print preview. Meanwhile, if you want to obtain more detailed data, you can export it as an EXCEL format file. Compared to the previous generation product, the control system of this instrument adopts a dynamic optimization zero displacement processing method, which improves the system error introduced by the uneven starting point test position in the test data. The theoretical calculation accuracy of flatness data has been improved to 0.05mm.

Compared with current three meter straightedge measuring instruments and other similar measuring instruments, this instrument not only has the advantages of high measurement accuracy, fast speed, reliable data, and scientific evaluation, but also has simple operation, reliable work, and greatly reduces labor intensity, improves work efficiency and economic benefits. Suitable for construction inspection, completion acceptance, and road maintenance of highways, urban roads, squares, airport runways, and other road surfaces. It can also provide reliable road surface analysis data for teaching, design, and research institutions. This instrument complies with JJG024-2011 standard.
