First,An Overview of the Barrel-type Rapid Measuring Instrument for Grain Moisture

Barrel-type rapid moisture meter for grainIt is a kind of high sensitivity, resistance type fast measuring instrument for grain moisture. Single-chip computer is used for measurement, non-linear conversion and power control. The circuit design is advanced and reasonable. The liquid crystal digital display is used for moisture display, and the temperature correction is automatically carried out, which reduces the trouble caused by artificial temperature conversion and compensation. TheBarrel-type rapid moisture meter for grainIt has the characteristics of stable reading, intuition, convenience, high measuring accuracy and fast testing speed. At the same time, the circuit uses many ways to reduce the working current, greatly reducing the power consumption of the whole machine, the battery is in normal use for more than a year, and has the function of automatic shutdown. Four section No. 2 ordinary dry batteries are used as power supply, which is easy to purchase, replace and carry. bookBarrel-type rapid moisture meter for grainIt can measure wheat, maize, soybean, rape, sorghum, japonica rice, indica rice and other grain varieties. It is suitable for the needs of grain acquisition, processing, storage, transportation, feed, seed, commodity inspection and other industries throughout the country.

II. Major Technical Indicators

1. Measuring varieties: wheat, maize, soybean, rapeseed, sorghum, japonica rice and indica rice

2. Measure the moisture range (temperature 20c):

Wheat 9&mdash- 20% corn 9 - 23% soybean 62% rapeseed 3&mdash16% sorghum 7.5-24.5%

Japonica rice 8-23,5% indica rice 7.524.5%

3. Main moisture range (temperature 20c): wheat 10&mdash- 18% corn 10&mdash20% soybean 8&mdash16% rapeseed 4&mdash13% sorghum 10-18% japonica 10-20% indica 10— 20%

4. Measurement accuracy:

A. Working error of main moisture range is less than 0.5%.

B. The operating error of other moisture ranges is less than 1%.

5. Instrument power consumption:

A. Start-up status: the current of the whole machine is less than 1 mA

B. Test state: The current of the whole machine is less than 5 mA, and the measured value is about 4.5 mA. The duration of each test current is only 0.5 seconds, and the other time is standby state current.

6. Automatic shutdown time: 1 hour stop operation

7. Power Supply: 2 # Dry Battery Section 4, L 5V×4=6V

8. Working temperature range—20c 45 C；

9. Volume and weight

240X 200 X 70 mm, weight I 5Kg after packing

III. Usage

1. Variety Setting Number Control Table

2. The sensor is well connected with the instrument.

3. Push the power supply to raise the level, turn on the power supply, display the current grain, and the whole machine enters the working state.

4. According to the tested grain varieties and the table instructions on the instrument panel, the grain is set on the corresponding number. The way to change grain is to hold the grain key for 2 seconds continuously, and then press the grain key to change the grain number after hearing a long ringing. Stop pressing the key for 3 seconds after choosing the tested grain, then change the grain number to stop flickering, and automatically enter the testing function.

5 & rsquo; screw off the top cover of the sensor and fill the cylinder evenly with a spoon. After vibration, scrape and close the upper cover, and screw the alignment thread evenly until the grain number disappears, stop rotation, and new data appear later. This data is the actual moisture value of the test sample. This moisture value includes temperature compensation, without manual calculation of temperature compensation. A cylinder of samples is based on the first measurement data. It is invalid to retest.

6. Pour out the sample in the barrel and clean the barrel with random tools for next test.-
