GeoDTS

AP Sensing’s GeoDTS automatically applies current on the electrical conductor of the hybrid cable and thus a defined heating power is dissipated along the cable in the ground. The resulting change in temperature over time along the optical fiber is measured and recorded simultaneously by the GeoDTS.

The entire heat and measurement process is controlled by the GeoDTS – just start the measurement program! The GeoDTS independently manages the measurement setup, the heat program. Furthermore the GeoDTS monitors voltage and current applied to heat up the fiberoptic hybrid cable and can handle two external electrical temperature reference sensors. Each instrument of AP Sensing’s GeoDTS series comes with a PC based evaluation software. This powerful easy-to-use package not only allows you to configure and visualize your measurement but also to calculate crucial thermal parameters like ground conductivity as a result of the executed measurement. All your measurement data is automatically stored on a SD card once you have started the measurement cycle. After finishing the measurement campaign just plug the SD card into your laptop and you get a comprehensive analysis after a few clicks.
