Bedrock Displacement Transducer

Bedrock Displacement Transducer KLB-B 100mm (-20 to +80mm) 

The KLB-B bedrock displacement transducer measures the amount of displacement between the mounting surface and a measuring point in bedrock. 
The KLB-B consists of a bedrock displacement transducer KLB-B, a hydraulic anchor (KLF-11/12), and a connecting rod (KLF-21). The KLB-B is equipped with up to 8 displacement transducers, so that 8 hydraulic anchors can be fixed in one borehole (φ66 mm or more for 1 to 6 points, φ86 mm or more for 7 or 8 points) for measurement. The amount of displacement between the displacement transducer and anchor is detected as relative displacement through the rod. 
The anchors are anchored to the bedrock by applying water pressure to the anchors at predetermined measuring points in the borehole using a pump from the ground.

More Information

Track inspection data recorder

Track inspection data recorder

This is a data recorder for measuring train track conditions. Track deviation data collected by each sensor is digitized and recorded on a memory card along with location information. The recorded data is processed on a personal computer, allowing for the creation of many data analysis and documentation materials, such as track maintenance data, with little effort.

Features
  • Capable of recording 500 km of continuous measurement data (standard)
  • Capable of measuring at high speeds (140 km/h)*
  • Motion measurement is possible at the same time as track surveying
  • Support for inputting various types of location information
  • Compatible with rail seam detector

 

*Depends on conditions such as the number of input points, measurement distance interval, etc. Please contact us for details.

  • Specification
    Analog input

    Max. 15 points
