CATEGORY > Extensometers + Compressometers

ROAD EXTENSOMETER

DESCRIPTION

The Road Extensometer is a single point extensometer which determines the stability and movement behavior of traffic road subgrades, when subject to processes such as tunnelling underneath the road. The Road Extensometer can be installed within a 100 mm (4 in.) or larger borehole diameter. An antenna is located at the top of the extensometer and includes a road-safe antenna cap.

The Road Extensometer is equipped with an internal DT2011B Data Logger which can be enabled for RSTAR (automated collection) or DT Link (semi-automated collection) Wireless Data Collection Systems. Wireless transmission of data collected from the Road Extensometer, via the road antenna, is sent to an RSTAR Hub in a fixed location, or to a portable hub in a DT LINK System. More information on the DT2011B, RSTAR and DT LINK wireless data collection options can be found by viewing their brochures at rstinstruments.com.

A range of up to 100 mm is available for 3-5 ft. extensometer lengths and up to 300 mm range for 6 ft. and longer. Shorter units, up to 6 ft., are shipped fully assembled with anchor depth adjustment in the field for deeper installations by adding extensions.

APPLICATIONS

Measure settlement and heave of foundations under roadways when subjected to processes such as tunnelling underneath.


Suitable for use in climates where snow plows are not required, thereby not damaging the antenna.

QUICK SPECS

Wireless data collection with RSTAR and DT LINK Systems.


No external power requirements. Long battery life.


Traffic rated.


No wires.


Rapid installation.


No obtrusive antenna.


Includes DT2011B Data Logger and Single Vibrating Wire Displacement Transducer in fully sealed housing.

BENEFITS

Increase Safety


Increase Productivity


High Accuracy


High Reliability
