Low Cost Sensing System for Dairy Products Quality Monitoring

The paper has described the design and fabrication works towards the development of a low cost sensing technique based on planar electromagnetic sensor operating with radio-frequency excitation. Computer aided computation being fast allows the on-line monitoring of the quality. The on-line sensing system suitable for the dairy industry needs to possess several key qualities including cost effectiveness, high reliability both in terms of measurement accuracy and speed of measurement. Also the sensor technology has to be able to perform volumetric penetrative measurement in order to measure properties through out the product and this could be achieved by employing planar type sensing technique
