FAQ#087 - Could the IPI, BH Profile and DEX probes have problems in frozen water?

Sisgeo suggest that frozen water within the inclinometer casings is to be avoided due to following reasons:

- Ice within the casing will affect functionality of the systems by blocking the individual probes;
- Mechanical damages can occur to the probes, but also to the inclinometer casing due to the expansion of frozen water

In any case, inclinometers and DEX probes can work until -30°C so that sensors will be not damaged.

What can be done to avoid this?
- insert a heating cable that keeps water temperature above 0°C;
- remove water from the inclinometer casing;
- place the inclinometer/DEX probes at locations where temperatures remain above 0°C.
