Flow is an important parameter in industrial production. In the process of industrial production, many materials, semi-finished products and finished products are presented in a fluid state. The flow rate of the fluid has become the key to determining the composition and quality of the product, and it is also an important basis for the accounting of production cost and the rational use of power. In addition, in order to ensure the reliability of trouble-free detection and testing results in the manufacturing industry, many processes require the consistent inflow and outflow of liquid or gaseous media, and in addition to pressure and temperature, flow measurement is also very important in the automated production process. Therefore, the measurement and control of flow is an important part of the automation of the production process. With the continuous development of flow sensors, more and more types of flow sensors are gradually coming out. IFM flow sensors are sensors that sense the flow of a fluid and convert it into a usable output signal, placing the ifm sensor in the path of the fluid, and measuring the change in the flow rate from the fluid-to-sensor and sensor-to-fluid interactions. According to the definition of flow rate, it is mainly used to detect the flow rate of gases and liquids.
The thermal miniature flow sensor uses an external heat source to heat the heating resistance of the sensor, and the heating resistance and its surrounding temperature distribution will be changed when the gas is active, and the mass flow rate of the gas is reflected by measuring the temperature change of the heating resistance or the upstream and downstream of the heating resistance. Thermal miniature flow sensors are divided into hot wire loss type, hot film temperature difference type, and heat pulse type. Because of the poor consistency of the hot wire lost gas flow sensor, it is difficult to produce it in batches; The thermal disturbance is large at low flow rate, and the hot wire has poor anti-pollution and corrosion ability; Factors such as electronic noise in the measurement, which leads to a decrease in its response speed, limit its further development. The hot film flow sensor has the advantages of small size, good sensitivity, high reliability, short response time, etc., the quality of the product is easy to ensure, the consistency is good, and its cost is low, which is very suitable for mass production. Glass-based flow sensors, which have a small thermal conductivity, do not require a structural diaphragm or thermal bridge, can sputter thin film resistors directly on the glass substrate, are simple to prepare, and can withstand the high pressure impact of the fluid at extremely high flow rates.
ifm flow sensor solutions. IFM flow sensor system hardware composition, by two diodes composed of a bridge circuit as a measuring probe, a certain temperature of fluid flow through the measuring probe at different flow rates, will make the measurement probe around the different temperature field, and converted into voltage for output. The output voltage is expanded by the voltage expansion circuit, and then converted into a digital signal by A/D, which is processed by a single-chip microcomputer, and then displayed through the digital tube. The control of the A/D conversion circuit and the digital tube display circuit is completed by the AT89C51 single-chip microcomputer control circuit, and the digital tube display circuit selects dynamic display. The power supply part is mainly composed of a regulated power supply with an output voltage of +5V and an output current of 1.5 A through the LM7805 integrated voltage regulator element at three terminals, which provides 5V power supply to all circuits.
