"The developed sensor is used to monitor the effectiveness of sand compaction online. The sensorÆs response measures the changes in sand compaction, which is affected by all the mechanics of the vibration system such as motor and linkage wear, changes in the sand properties such as fine content and loss on ignition percentage, and environmental changes such as temperature and humidity. The differential nature of the sensorÆs measurement is intended to reduce the deviation in sensor evaluation of compaction effectiveness due to environmental factors."
