PIVOT LASER EXTENSOMETER

DESCRIPTION

The Pivot Laser Extensometer is a portable device designed to measure the relative distance between two or more reference points fixed to an excavation surface or a structure. This instrument is ideally suited to the repeated precise measurement of distances between points in an underground opening or excavation.

The instrument consists of a portable precision laser distance meter which is temporarily connected in the field to a permanent wall or floor anchor point and then aligned toward permanent target points installed around the opening. The distance measurement between the two points is recorded by an integral datalogger unit for later download and analysis.

Instrument anchor points and target points are provided separately, and can be combined in any configuration required.

A tilt meter is included with internal trigonometric reduction of horizontal and vertical components.

The Ultra-Rugged Field PC2 (readout) is programmed with location names to automate data reduction.

QUICK SPECS

Minimum measurement length of 1.5 m.


Maximum measurement range of 50 m.


Measurement resolution of 0.1 mm.


Repeatability of 0.3 mm.

APPLICATIONS

Mine development in moving ground; measurement of roof sag and squeezing ground.


Measurement of tunneling convergence or dilation.


Measurement of surface movement between points.


Monitoring and control of NATM construction.

BENEFITS

Increase Productivity


High Accuracy


High Reliability
