When connected with code wheel, it can acquire the rotation turns of the code wheel by measuring the pulse count. Then calculate the length by the wheel perimeter.  When connected with tension meter， it can acquire the surface tension value by analog acquisition and A/D conversion. 

Apply for the depth and surface tension data acquisition of the Haliburton EXCELL-2000surface system.

Adopt enclosure structure, there are display screen and operation button at the front panel, fixed outlet at the back panel, join up code line and tension line, internal adopt intelligent control and acquisition system.
