Abstract: A hay bale moisture measuring device comprising a bimetalic, probe forming a single cell battery uses the hay and the moisture therein as the electrolytes to provide an internal cell resistance measurement which is calculated in an electronic circuit according to a predetermined algorithm into a hay moisture measurement which is further biased for hay temperature, bale configuration, hay type, cutting and density by the same circuit.

Abstract: A portable grain moisture meter has a large 16 character digital display allowing an alphabetical list of grain selections to be selectably displayed in full text format and subsequently tested for moisture content with the test results also displayed on the same display. The meter also has provisions for calibrating the meter to a remotely located meter and has dual temperature transducers for achieving automatic grain temperature compensation by monitoring both the grain temperature along with the cell temperature.

Abstract: A combine thresher has a multiple plate impedance cell grain moisture analyzer assembly with two of the plates being outside mounted ground plates to reduce EMI and RFI interference and provide more accurate moisture measurements. The assembly is ex-situ mounted to bypass a part of the grain flowing from the grain floor of the harvester to the grain accumulation bin to measure the moisture thereof and to exhaust same back into the mentioned grain flow. The analyzer has a bin full sensor to activate the bypass only when the analyzer is full for accurate moisture measurement.
