Abstract
To improve concrete quality
a design project for detecting sand weight using the cylindrical capacitive sensor is proposed.The configuration of the sensor is designed
and a new type of measurement circuit of small capacitance is adopted.This method is convenient and feasible proved by experiment.So a new reference method to measure sand weight is provided.
