Development of photon counting technique to operate from discrete photons to continuous regime using DAQ card in LabVIEW platform

Indirect Measurement of the Airflow Fed to a Flotation Device, through the Measurement of the Voltage Generated by a Photoelectric Cell

“…Figures 2 and 3 show the graphical interface and the programming panel, built-in LabVIEW®. The computer program was designed to obtain data every half second for 20 seconds, thus obtaining 40 voltage data for each supplied air flow (2,3,4,5,6,7, and 8 L/min).…”

“…LabView® (Laboratory Virtual Instrument Engineering Workbench),is a computer package for data acquisition through sensors, used by many industries, as well as educational, and research institutions. This program, developed by National Instruments (NI), is used to collect and display data; and offers extensive acquisition, analysis, and presentation capabilities in a single environment [1]; it is used because it has an intuitive and user-friendly environment, as seen in the different applications mainly in the metal-mechanical industry [1,2,3,4,5].…”

“…In this particular case, the airflow measurement is done before entering the flotation systems; Due to the mineral and metallic components that interact in the system, this becomes complicated, so the aim is to measure the airflow by relating the voltage generated by a solar photocell, by passing a beam of light through the medium. The use of photovoltaic cells or the use of photon counters offers practical advantages over existing counters, such as compactness, since it is interconnected to the computer motherboard, in addition to low power consumption, high count rate, and ease of interconnection [5].…”

PLC-based mechatronic-hydraulic integration experimental platform measurement and control system development

“…Therefore, teachers should make full use of this advantage and continuously improve and optimize the existing system structure, so as to further promote the development of China's education. In practical application, the S7-200 series programmable controller can be used as the master station and combined with various sensors and actuators to form a complete automation line [10].The communication flow diagram of the measurement and control system is shown in Figure 5. Among them, the master control unit adopts the STEP7V5.4 software development kit introduced by Siemens, and the overall performance of the system can be effectively improved by this way.…”
