轻量级的挠度计 (LWD)

轻量级的挠度计s (LWDs) are increasingly being used to determine overall compaction quality of all types of earthworks through their use as a QC/QA field test. LWDs provide a rapid determination of elastic modulus, which is an essential factor in mechanistic design and can be used as an accurate assessment of compaction. An LWD is used for measuring the bearing capacity (deflection) of subgrade/subsoils and unbound base layers, granular layers and backfilling materials, 符合ASTM E2835-11. Based on the static plate load test requiring a load vehicle, LWD提供了一个简单的, fast and repeatable test providing an accurate assessment of compaction parameters. Applications for this non destructive method of testing include bearing capacity and compaction include road construction, 管道、电缆回填, 铁路路基, 机场跑道/滑行道的, 大坝建设, 堤防, foundations and other earthworks.

Humboldt offers two versions of the 轻量级的挠度计s from HMP – deluxe models: the HD-4129.3F(10公斤)和HD-4159.3 f(15公斤) and basic units: the HD-4130.3F(10公斤)和HD-4149.3 f(15公斤). Both units are the same mechanism and differ only in the controller used with each one.

LWD的 is calibrated at time of manufacturing and comes with a calibration certificate. The calibration is valid for 1 year.

豪华模型:
hd - 4129.3F和HD-4159.3F feature a deluxe controller that includes:

• 一个大的，2.2 x 2.87" (56 x 73mm) colorful display
• light sensor-controlled backlighting that provides the optimum readability even in bright sunlight
• 简单的菜单导航
• 集成全球定位系统(GPS)
• 集成wifi
• interface for a thermal printer and USB
• 帮助功能
• efficient and fast 32-bit processor
• internal memory for up to 1000 tests
• high-performance rechargeable battery

The graphic interface of the deluxe models provides an intuitive menu, which guides the user through the testing procedure and provides real-time test results. Measured data is presented in tabular, as well as curve formats with date. time and 全球定位系统(GPS) location clearly depicted. This data can be exported from the control unit via USB or wirelessly directly into the Cloud or to your PC for archiving and further processing. This allows personnel in any office to have access to data while you are still on site testing. It is also possible to print out results to a small portable printer on site.

使用 of the web-based evaluation software: HMPreport, provides the ability to produce professional reports for each measuring point, which can include your logo and contact details. This software allows you to work with your data from the Cloud or your PC. The software also enables you to store the data in a database with easy-to-use search and editing options.
