摘要： A density measurement system for measuring the density of a material within a region, the density measurement system comprises: a plurality of electrodes arranged around the region; an energisation source arranged to apply an electrical signal to at least one of said electrodes; a monitor arranged to monitor an electrical parameter at at least one of said electrodes, the monitored electrical parameter being caused to change in response to flow of electrical current within the region; and a processor arranged to: generate data indicative of the complex impedance of the material within the region based upon the monitored electrical parameter; and generate data indicative of the density of the material based upon the data indicative of the complex impedance of the material.

摘要： A measurement apparatus comprising: a plurality of first electrodes, each of the first electrodes being spaced apart by at least a first predetermined spacing; a plurality of second electrodes, each of the second electrodes being spaced apart by at least a second predetermined spacing less than the first predetermined spacing; an energisation source arranged to energise at least one of said first electrodes so as to cause an electric field to be established between at least one pair of said first electrodes, and to energise at least one of said second electrodes so as to cause an electric field to be established between at least one pair of said second electrodes; a monitor arranged to monitor an electrical parameter at at least one of said first electrodes in response to said energisation of at least one of said first electrodes and to monitor an electrical parameter at at least one of said second electrodes in response to said energisation of at least one of said second electrodes; and a controller arranged to generate data indicative of a property of a material within a first region extending a first distance from the first electrodes, and to generate data indicative of a property of a material within a second region extending a second distance, less than the first distance, from the second electrodes, based upon said monitored electrical parameters.
