Settlement Transducer

KLA-A Settlement Transducer
NKLA-B TML-NET type Settlement Transducer　100 mm to 200 mm

This is a settlement gauge that is set on a ground surface to measure the settlement of each ground layer. Special anchors are placed at target positions in a borehole, and the displacement between the anchors and the ground surface is measured. Measurement can be made at a maximum of six levels in one borehole.
* For information on network-capable NKLA-B, see special measurement systems.

 

Protection ratings : IP 45 equivalent

More Information

Stratified Settlement Meter KLC-50A 50mm

Anchors and settlement meters are connected at arbitrary intervals in a borehole to measure sectional displacement.
It is suitable for measuring the amount of rebound and settlement of excavated ground and embankments. The maximum number of connection stages in one borehole is 8.

 

Protection class IP 68 or equivalent

ing-klc-001
Features
  • Excellent water resistance
  • No need to replace instruments when excavating the ground
  • No risk of instrument damage during construction
  • Capable of measuring settlement in up to 8 connected layers

    Output polarity

    The measured value changes in the positive direction as the distance between the water hydraulic anchors increases.
    The output changes in the minus direction when the distance between the water hydraulic anchors gets closer.

Stratified Settlement Meter KLC-50B　50mm

The current KLC-50A was installed with the initial position fixed and released with a release wire.
However, it was not possible to confirm whether the fixation was released, and there was a possibility that it remained fixed.
This time, the fixing mechanism was eliminated and the method was changed to adjust the initial position while pulling up the main body of the KLC.
After installation, the sensor's movable part and the grout were completely disconnected to ensure that the ground behavior could be accurately captured.
