Depth Tracking Unit (DTU)
Using a combination of Hookload Sensor and a Rotary Encoder, the Depth Tracking Unit automatically tracks bit depth in drilling applications. The unit is designed to be directly compatible with the Geolink system, but may be operated independently as part of other MWD/LWD surface systems.
As a supplementary function, the unit also provides Instrinsically Safe power and serial communications for rig floor tool configuration and download.
