An in situ measurement system for oil palm fruit's
permittivity and moisture content determination is presented. The
instrumentation is includes a six-port reflectometer and an open ended
coaxial probe which operates at 2 GHz. The developed system was tested and
compared with the data obtained using commercial dielectric measurement
probe and mixture model. This system is found to be practical for in situ
measurement as well as fast and cost effective for oil palm fruit's
properties and quality inspection.
