DAT instruments, DAT WXYZ inertial sensor

DAT WXYZ is a high technology inertial sensor to be installed on diaphragm walls grabs. It measures and records several parameters:

  • inclination (provided by internal biaxial tilt sensor);
  • deviation (provided by internal biaxial tilt sensor and external depth sensor);
  • rotation (measured through internal compass).

Data is recorded in real time and stored on internal memory. DAT WXYZ inertial sensor can be connected wireless to a PC or to the JET DSP 100 / D datalogger. Case is waterproof and very strong: it is made of delrin and stainless steel materials.

DAT WXYZ inertial sensor, installation

Sensor is installed on the dwalls grab. The schematic below shows all sensors installed together with DAT WXYZ inertial sensor. Depth sensor is necessary to measure dwall depth. Deviation is calculated by dwall depth and biaxial inclination.
