The equipment can make a difference in the accuracy of a dynamic plate load test. For this reason, discerning builders use only a light weight deflectometer from a trustworthy manufacturer, like Terratest, which is known for developing tech-savvy and innovative measuring instruments designed with the customer’s requirements in mind. Currently, they offer two models of light falling weight deflectometer to quickly and easily check soil compaction’s quality in construction sites. You can choose between an LWD with a cable and a wireless version with Bluetooth. Each product has its own unique special features, but they also share similar qualities.
Every Terratest Light Weight Deflectometer is fully equipped with high-performance features, such as a dependable rechargeable battery, GPS system, USB drive, printer, PC software, and text input function. Both wired and wireless models are made in Germany and backed by the best price guarantee. Terratest is also known for adopting the latest technologies, which they apply on their devices. The Terratest 5000 Blu is a result of that, and it features voice navigation, Bluetooth capability, and the ability to be controlled from an Android app.
The Bluetooth light weight deflectometer was initially presented in Munich in 2013 and it continues to be a trusted equipment that tests soil compaction without a cable connection. The results are transferred from the load plate to your smartphone or tablet via Bluetooth, so there are no wires to get in the way. This makes the LWD practical for testing in awkward areas or where wires could be an inconvenience to the operator.
Both the wired and wireless light weight deflectometer of Terratest are designed to suit the requirements for dynamic load plate testing under the ASTM E2835-11 standard. They have their own calibration system, which is accredited by the German Federal Road Research Institute. They come with a weatherproof box to protect the electronics from damage. External control buttons are included on the box for easy operation. The screen display is integrated with the GPS system, and the rechargeable battery can keep the LWD running for over 2,000 tests or up to 600 printouts. Evaluating, analyzing, and managing data are made easier with a powerful PC software. You can use the USB drive to transfer data to your PC.

The Light Weight Deflectometer is an advanced device designed to determine the non-cohesive sub-bases, compaction quality, pavement improvements, and bearing capacity of the soil. It comes with a dynamic plate load tester which tests the inbuilt soil layers. This machine is suitable especially for the hard to access sites. It is mainly used in railway engineering and road construction. It is also used to examine foundation fillings and roadbeds.
This tool delivers measurement results instantly. Moreover, it is easy to handle. The Light Weight Deflectometer is ideal for testing soil quality in confined spaces like bridge culverts, and pipeline trenches. It’s a unique structure and ergonomic design makes it a highly reliable device which can be easily operated and transported. The device also has a transportation lock for safe and secure soil measurement.
The load plate of the deflectometer comes with the bubble level and practical handgrips which help in aligning the loading mechanism. This robust device has a long life and good precision, as it’s crafted with the best quality materials. Moreover, the deflectometer can be used even in extreme weather conditions as it is splash-proof.
How to measure soil quality in two minutes using the deflectometer
Position the Light Weight Deflectometer, connect the measurement device to it and then switch it on. The process of soil measurement begins once the ground is pre-compacted. This process takes four consecutive compressions. Proper structuring of the HMP LFG menu is important for the smooth functioning of the device.
The display shows the settlement in mm after a compression process is completed. Once the measurement process is finished the device shows the average measurement value of the dynamic deflection module, the settlement and the speed ratio. The analysis is simplified further automatic completion of the dataset.
You may get a printout of the measurement series and analyze them on the site. The printed data includes the time, current date, settlement rates, average value of the settlements, the settlement curve, dynamic deformation modulus and path-to-speed ratio. The measurement values can be transferred to the desktop for a detailed analysis of the measuring points.
