Recommendations for direct burial of remote sensor:
● Check for visible damages in paint finish !
● Use protection conduit !
● Protect sensor with pea gravel at least 300 mm around sensor. This provides some
drainage and also avoids caking sensor with earth. It also helps to locate sensor in case
excavation takes place.
