4Anhui Online Compound Fertilizer Moisture Monitoring InstrumentUsage and operation:

1The LCD data display window includes:

① Moisture displayXX%Display the moisture value of the currently tested object passing through the sensor.

② Type display: The currently set type number of the tested object.

③ Temperature correction: The operator selects the appropriate temperature value based on the situation.

④ Moisture correction: Operators select appropriate calibration error values based on the situation

⑤ Setting display: Display the current upper limit alarm setting value.

2The button functions include:

① Type key ② Temperature key ③ Correction key ④ Set upper limit key

1Moisture display;

2Adjustment of the classification of the tested object;

3Temperature adjustment of the tested object;

4Correction of moisture value of the tested substance;

5Set the upper limit of moisture alarm;

6Output switch signal beyond the set value;

7Output4－20mA / 0－5VSignal;

8．RS485 / RS232Connect the computer.

The instrument consists of two parts, one is the sensor and the other is the host.

• The sensor adopts Japanese technology and uses high-frequency emission method to collect the moisture content of the measured object. Due to the different moisture content of the measured object, the frequency collected into the sensor is different. The frequency current is converted into current or voltage signal and enters the host.

Sensors are divided into two types:1For contact type,2It is non-contact. (Choose one based on different measurement environments)

1Contact sensor: It can continuously measure the moisture content of flowing grains. When measuring, the sensor probe can be inserted into the compound fertilizer to continuously measure the moisture content of the compound fertilizer.

2Non contact sensor: The sensor can be fixed above or below the moving object, and when the object passes through the sensor, it can measure moisture in a non-contact manner.

II The host part consists of an intelligent small computer and a control part. It processes the collected sensor voltage signals by the computer and displays the corresponding moisture values on the LCD screen. The display screen can also show parameters related to upper limit setting values, types, error correction, temperature correction, etc., and is equipped with operation keys. The instrument can control peripheral devices through a computer and output upper limit control thresholds,4~20mAMoisture corresponding control current, equipped with485The interface is connected to the computer serial port to achieve computer monitoring. The instrument can measure the moisture content of fertilizers such as fertilizers, organic fertilizers, and compound fertilizers.
