840527-000 is a kind of microdot moisture meter which can detect the moisture content of grain grain. It is widely used in many industries such as agriculture, food, feed and feedstuff, fishery, tobacco, papermaking and biomass pellet production.

The working principle of 840527-000 microdot moisture meter is based on the fact that the dielectric properties of grain grain vary inversely with the moisture contents. Grain grain absorbing moisture generates dielectric conductivity. The device can measure the dielectric conductivity of the grain grain and then calculate the precise moisture content.

To measure the moisture content of grain grain, 840527-000 adopts the "contactless" measuremeng method, which is to obtain the dielectric properties of grain grain in the way of tuning the pulsed high frequency rectangular signal to measure the grain grain. Under the high frequency magnetic field generated by the transmitter above the grain grain to be tested, the grain grain will absorb the moisture and the media around the grain grain will be dielectric conductive, and the dielectric conductivity of the media is proportional to the moisture content.

The core part of 840527-000 microdot moisture meter is a high-frequency circuit composed of a signal generator, a power amplifier, a frequency divider, a control circuit and a method of restoring sine wave output of the transmitted signal. The power amplifier increases the signal generating output to an appropriate level. The signal generated is further divided into many small segments, so as to continuously adjust the measuring frequency according to the characteristics of the sample and reverse the measured signal to sine wave output. The measuring frequency is selected in a frequency range that has a greater effect on the measured sample, so as to measure more detailed information about the sample. The frequency range is 19.2 MHz - 21 MHz. A control circuit is provided for setting the working parameters of the instrument and displaying the measurement results. The dielectric power of grain grain is measured in the form of "contactless" measurement and the moisture content is calculated according to the measured dielectric power

840527-000 microdot moisture meter is mainly used in the detection of grain grain moisture content. It is widely used in the production process of grain grain and its related product, such as quality assurance, process management, storage control and it also can be used in large grain grain processing and storage enterprises to monitor grain grain and provide basis for enterprises to adjust production and storage. With a high degree of accuracy and high-speed measurement, 840527-000 microdot moisture meter has become an important tool in the field of grain grain inspection.
