Name: Digitilt AT System
SKU: 502
Availability: InStock

Slope Indicator’s Digitilt AT system provides a modern alternative to the classic Digitilt inclinometer system. The system includes a digital probe, lightweight control cable, Bluetooth reel, cable gate, Digitilt Reader app, and DigiPro2 software for the PC.

Application:

Inclinometers are used to monitor subsurface deformations of the ground in landslides, embankments, and dams and around deep excavations and tunnels. Inclinometer casing is installed in a vertical borehole that passes through suspected zones of movement into stable ground. The Digitilt AT system is used to survey the casing. The first survey establishes the initial profile of the casing. Changes in the profile, revealed by comparing subsequent surveys to the initial, indicate that ground movement has occurred. Plots of inclinometer data show the magnitude, direction, and rate of ground movement.

Survey	Displays list of inclinometers. Tap to start a survey. Tap and hold to edit inclinometer parameters
Survey Screen	Large, readable characters. Shows active depth, depth last recorded, A and B readings in mm, inches, or sine units, checksums, and progress bar. Record button prompts user to wait, tap, or pull. Other features include easy depth changes and automatic bookmarks
Plots & Data	Plots checksums, profiles, change-from-initial, and change-from-last in high resolution. Displays data table for inspection and survey-time corrections
Send	Sends inclinometer data to PC as email attachments or syncs via Dropbox. If internet is not available, data files are transferred via USB cable and Windows file manager

Digital Probe – The Digitilt AT probe responds quickly, providing performance similar to the classic Digitilt system. Its short length and high quality wheels provide reliable tracking through tight curves.

Lightweight Control Cable – Easy to carry and easy to handle, the lightweight control cable is also easy to read. Metric cables are graduated at half-meter intervals and labeled at meter intervals. English cables are graduated at two-foot intervals and labeled every four feet.

Compact Cable Gate – The compact cable gate replaces the classic pulley and is compatible with all three casing diameters. The cable gate aligns cable graduations precisely at the top of the casing, eliminating the potential for offsets and placement errors.

Android Reader & Bluetooth Reel – The modern Android OS supports high-resolution screens, touch-screen interfaces, and full internet connectivity.

The Bluetooth reel provides forty hours of operation on one charge and is available with 30, 50, 75, or 100 m of cable. English systems are available with 100, 150, 200, or 300 feet of cable.

Digitilt Reader App – The Reader app is central to the system’s simplicity and power.

Scan starts a survey from a QR code.
Survey starts a survey from a list of inclinometers.
Plot shows checksum, change, and profile plots.
Send transfers surveys by email or Dropbox.

Survey – Survey screens are bright and easy to read. At each depth, the Reader displays A and B readings in mm or classic “sine” units. English systems display readings in inches or sine units.

The Reader prompts when the readings stabilize. To record, simply pull the control cable upwards to the next depth. The Reader senses motion and stores the last stable reading. There is no need to hold the Reader or tap a button. Your hands stay free to work with cable and probe.

Plot – When the survey is complete, tap to generate instant high-resolution plots of checksums or changes. Use the plots to validate the survey before you leave the site. Share them by email or Dropbox, if you like.

Send – It takes just a single tap to email multiple surveys to the office or transfer the surveys by Dropbox, Google Drive or other web services. The process is simple, even after a hard day in the field. If the internet is not available, you can also transfer readings via a USB cable. (No drivers or software are required).

DigiPro2 Software – DigiPro2 software creates inclinometer databases, manages inclinometer data, generates plots and reports, and provides advanced routines for identifying and correcting systematic errors in data.

DigiPro2 works with both the Digitilt AT system and the Digitilt Classic system.

Download the Digitilt Reader App – The Digitilt Reader app is available free from Google Play. Currently supported devices are:

7-inch, RT-V7000 Rugged Tablet – 50330980

If you have one of these devices, scan the QR code at right or search for the app on Google Play.
