The development of microcomputer automatic particle counter to pursue sedimentation
Microcomputer automatic particle counterMicrocomputer automatic control, touch sensitive buttons, * automatic operation, LED display of set and actual numbers, adjustable counting speed, no noise, high precision, all metal shell of the whole machine, novel and beautiful appearance, sturdy, with circuit self-tuning, adjustable speed, setting viewing, arbitrary counting, preset self stop and other functions.
Microcomputer automatic particle counter is a type of particle counter, which generally consists of a main unit and a sample tray. The SLY-A and SLY-B electronic automatic grain counter are instruments specially developed for the seed department to measure the thousand grain weight of seeds. This grain counter adopts microcomputer automatic control, touch buttons, * automatic operation, with circuit self-tuning, adjustable speed, setting viewing, arbitrary counting, preset self stop and other functions. It can count small and medium-sized seeds such as rice, wheat, rapeseed, etc. The microcomputer automatic grain counter is a digital display electronic measuring instrument that can automatically count crop seeds such as rice, wheat beans, rapeseed, and sesame.
By using this microcomputer automatic counting instrument, not only can counting time be greatly saved, but counting is also accurate and reliable. The successful development of the grain counting instrument provides advanced measuring equipment for agricultural research institutions, agricultural colleges and universities, seed systems, and grain departments to test seeds and measure thousand grain weight.Microcomputer automatic particle counterThe performance is relatively stable, with a counting error of no more than 4. It takes about 3 minutes to count 1000 seeds. When the external AC power supply changes within the range of 190-220 volts, the instrument can work normally. The microcomputer automatic grain counter has been tested by relevant agricultural departments and has achieved good results. In order to achieve high counting accuracy, more stable T-work performance, and wider applicability of the multi-purpose counting instrument, we have made significant modifications and designs to the original circuit of the counting instrument.
The operation of the microcomputer automatic particle counter is controlled by a micro electric rib chip and operated by thin film buttons. The electromagnetic vibration box causes seeds to be queued and fed one by one, forming photoelectric pulses after falling into the photoelectric conversion tank. After amplification, shaping, and inversion, they are sent to the counting circuit and displayed on an LED digital tube for reading. Microcomputer automatic particle counter electromagnetic vibration feeding device: Seeds are placed on the tray, and the material groove is spiral shaped. The seeds that rise in the spiral groove reach the dropping port and fall down. They are projected onto the silicon photovoltaic cell through the photoelectric conversion area to generate current changes. After pulse amplification and shaping, the photoelectric count pulsation is obtained and sent to the microcomputer controlled counting display circuit.
Pre setting and viewing circuit of microcomputer automatic particle counter. Press the "Settings" button, and the digital display will switch to the setting environment. Use the "Up", "Down", "Left", and "Right" directional keys, where "Down" indicates the addition or subtraction of numerical values, and "Left" and "Right" indicate the movement of the setting value to set the preset value. After setting, press "Settings" again to push out the setting environment, and the digital display will show 00000. Users can viewMicrocomputer automatic particle counterPreset value, press the "View" button, and the view function will automatically return to the user's previous digital display.
