About

Ballbank

This digital inclinometer helps determine safe advisory speeds for road curves. It measures superelevation, vehicle roll, and lateral acceleration, recording data and video of your drive for analysis. Supports both Imperial and Metric units.

Highlights
  • Measures superelevation, roll, and lateral acceleration
  • Records drive data and saves as video
  • Calculates maximum angle, average speed, and lateral g-force
  • Records linear distance, lat/long, altitude, date, and time
  • Map view for data collection locations
  • Imperial and Metric unit support

Improving roadway safety, one curve at a time. Designed with precision, easy to use, and beautifully crafted, Ballbank is a digital inclinometer used for determining advisory speeds for horizontal roadway curves. It measures, in degrees, the combined effect of superelevation, vehicle roll, and lateral acceleration. For decades, the ball bank indicator method is one of the most commonly used methods by engineers worldwide for determining driver discomfort that correlates to setting the advisory speed. Setup your phone on your dashboard like you would typically setup a ball bank device. Press Start and drive. No need for a second person to write down the results. Ballbank records all of the data that you need and saves it as a video directly to the Photos app. The raw data, including all of the curve data results, is saved as a text file. The text file can be exported and emailed. Ballbank not only shows you the continuous angle reading and speed, but calculates the maximum smooth angle, average speed, and lateral g force for every curve. Linear distance, lat/long, altitude, date, and time are all recorded too. The map makes it easy to see exactly where all of the data was collected. Ballbank records the video of your drive, which allows you to evaluate the driver performance on every curve, document all of the existing signs, assess the site safety, and verify pavement conditions that could impact the results of your testing. Both Imperial and Metric units are supported.

Pundit Array: Consolidated power in a single device for structural imaging, object and defect detection with ultrasound pulse echo. Also including wide area grid scanning for thickness and pulse velocity variation mapping. The idea behind Pundit is timeless: to make deep concrete imaging effortlessly precise and clear. Rugged, modular arrays of ultrasonic transducers deliver reliable defect localization and thickness measurement of concrete structures. Pundit Array app and the new Pundit PD8050 transducer array build on that theme: together they are the world's lightest, wireless, AI - assisted and cloud-enabled inspection solution of its kind. This solution allows you to scan deep into concrete faster than has ever been possible before. Uniquely create large scale 2D and 3D images and view with augmented reality directly on site. Improve your inspections with unmatched image precision, sharpness, focus and stability thanks to sophisticated algorithms. Scan over wide areas with the grid scan mode and create heat maps to localize variations in thickness. Combine this with the unique pulse velocity tag to localize variations in concrete quality. Or go further and use this in combination with the methods described in the European standards EN12504-4 and EN13791 to estimate concrete compressive strength. Enjoy the new features included in this app release to increase on-site productivity with a clean, intuitive user interface. Make measurements a breeze with real-time image adjustment, auto-gain, assisted calibration and automated positioning. Annotate measurements with photos, voice memos and comments in the Logbook. Access and share with colleagues anywhere anytime, thanks to the Screening Eagle Technologies Workspace environment. Export raw data of your measurements for post-processing in third party applications. Ultrasonic Pulse Echo detects structural features and flaws other technologies cannot see, and that is why it is the perfect complement to structural inspection with Proceq GPR Live and Profometer PM8000. Download the free app now and explore the state of the art ultrasonic pulse echo with the included demo files.
