Description
Technical field
The utility model relates to a kind of cotton moisture content surveying instrument, particularly has a plurality of battery lead plates as the cotton moisture content analyzer of surveying water sensor, belongs to gauging instrument.
Background technology
Cotton all contains moisture under the natural air state, the physicochemical property and the mechanical mechanics property that how much not only affect cotton fiber of its water cut, particularly directly affect the weight of cotton, and the weight of cotton is the leading indicator of transaction, the standard moisture of national regulation cotton is 8.5%, and the moisture absorption of cotton is diffusing moist very strong, and for guaranteeing the accurate of cotton transaction index, the water cut that accurately measures cotton is vital.The cotton that water cut is different has different electric conductivities, and is moisture many, conducts electricity very well, moisture few, and poor electric conductivity adds certain DC voltage to it, just can detect the water cut of cotton by the resistance of measuring cotton.
The present similar detecting instrument that generally uses, its critical component are surveyed water sensor and all are made up of the pair of electrodes plate.This electric-resistivity method instrument that has only a pair of potential electrode plate, expect measurement result accurately and reliably, must guarantee the moisture homogeneity of tested cotton sample, the water cut that is the sample each several part is identical, otherwise, meeting makes test result be subject to moisture some effects bigger than normal because of the parallel connection effect of the different resistances of each several part different water cut cotton fiber formation, causes test error.For head it off, the method for now taking is, sample is made regulation, requires it moisture evenly.This requirement is to be difficult to satisfy, so the moisture unevenness of sample has just become the main source of instrument test error yet in actual applications.
The utility model content
The purpose of this utility model is a kind of can the minimizing significantly because of the moisture inhomogeneous multipolar system cotton moisture content analyzer that influences the test result accuracy of cotton sample of design.
The technical solution of the utility model is:
A kind of multipolar system cotton moisture content analyzer, include casing, display device, propulsion system, circuit unit and pole plate group, described pole plate group is made up of fixed polar plate and movable pole plate, and described fixed polar plate is made up of the battery lead plate that a plurality of sizes are equal and insulated from each other on the same plane.
Described movable pole plate is made up of the battery lead plate that a plurality of sizes are equal and insulated from each other on the same plane.
The battery lead plate quantity of the movable pole plate of the battery lead plate of described composition fixed polar plate and composition equates, battery lead plate is oppositely arranged in twos.
When fixed polar plate or movable pole plate one of them or all be that the equal and insulated from each other battery lead plate of a plurality of sizes is when forming, a kind of situation is: fixed polar plate or movable pole plate that a plurality of battery lead plates are corresponding as a whole, another kind of situation is: the battery lead plate of the corresponding same quantity of a plurality of battery lead plates, no matter a plurality of battery lead plates and pairing be can form independently a plurality of circuit loops between integral body or the fixed polar plate of same quantity or the movable pole plate, promptly can measure its water cut respectively to the white Hupeh anemone root and leaf of placing wherein that contains.
Effect of the present utility model is: can make the cotton sample because of the moisture irregular adverse effect that causes reduces significantly, test accuracy is greatly improved.
