Digital Grain Moisture Analyser

It is based on capacitance variation technique. The instrument comprises of mainly an analog section and a digital section. For controlling the complete functioning of DGMA, it uses power efficient, high speed microcontroller (MCU) chip. The sensing system is made up of capacitive transducer that converts moisture contents into an electrical signal. Presence of a very small quantity of water causes considerable change in the dielectric constant of the sensor cell. These moisture variations change capacitance and in turn are measured in terms of frequency variations. These variations are then further trend fitted and calibrated in terms of percentage moisture. The final result in terms of moisture percentage, temperature of sample, date and time of measurement is displayed on LCD for a given sample under measurement.

For grain harvesting, procurement, storages and food processing industries, etc to ensure right quality and perseverance of quality.

Very small quantity of moisture can also be measured
