Problems solved by technology

[0003] At present, there are many deficiencies in the flow control in the processing process, such as the traditional method of displaying through the instrument, and then controlling the flow. This method is inaccurate and difficult for some flow control with high precision requirements. In the flow control method of the sensor, the pressure sensor is easy to cause damage to the pressure sensor when the flow rate is too large, and the pressure sensor often needs to be replaced, and the installation and use of the pressure sensor is inconvenient. In addition, the flow controlled by the traditional method is used in a small dark space or inside the instrument There is no way to realize the detection of data, therefore, a composite flow pressure sensor device is proposed to solve the above problems

Embodiment 1

[0025] It is applied in the vacuum coating industry to realize precise control of the argon inside the pipeline. First, install the pipeline 6 inside the argon pipeline, set the initial value through the control terminal 18, and transmit the initial value through the wireless transmission module 17 Inside the single-chip microcomputer 19, the single-chip microcomputer 19 stores the initial value. When argon gas with different sizes of flow is needed, the single-chip microcomputer 19 is controlled by the control terminal 18, and the single-chip microcomputer 19 controls the rotating speed of the micro-stepping motor, thereby controlling the rotation of the rotating plate 7. Accurate control of the flow rate inside the pipeline 6 can be realized, and precise control of the output of argon gas can be realized.

Description

technical field [0001] The invention relates to a pressure sensor device, in particular to a composite flow pressure sensor device, which belongs to the technical field of sensor application. Background technique [0002] With the rapid development of industry, the requirements for product quality and processing precision are getting higher and higher. If the product quality is to be guaranteed, the product must be strictly controlled during the processing process. In the current processing process, It is very important for the processing of some precision instruments or the control of the internal flow of the pipeline. The pressure sensor is the most important component for the control of material processing and flow. Therefore, the pressure sensor plays an irreplaceable role. [0003] At present, there are many deficiencies in the flow control in the processing process, such as the traditional method of displaying through the instrument, and then controlling the flow. This...
