Gas flow sensors can display the cumulative flow, instantaneous flow, temperature and pressure of gases, and it is widely used in all walks of life, such as industrial production, scientific experiments, power saving, etc., and plays a role in promoting the production power of progressive society.
In order to detect the flow rate of gas, we can use a professional gas flow sensor to detect, which not only has the fundamental detection target display function, but also has a communication function, which can communicate with the substation, and display the output of the accumulated flow, pressure, temperature and other target factors. The use of gas flow sensors is very widespread, and has a great impact on the development of many professions, such as industry, scientific experiments, power saving, etc., have made great contributions. At present, convenient and practical products are urgently needed by society, and with the advancement of scientific skills, gas flow sensors are increasingly able to meet the needs of society. While gas flow sensors are being miniaturized, advances in their detection functions can also contribute to the development of society.
At present, the domestic gas flow sensing skills are not sophisticated, and most of the domestic products are imported. It is mainly produced abroad by Japan, Switzerland, Netherlands, Europe and the United States, which are countries with thriving skills, and with their advanced semiconductor skills, they vigorously develop gas flow sensors, and currently have a high reputation in the world. However, on the whole, such products on the market are actually incompatible with each other, and the products have not yet achieved real commercialization, and the use is not universal, and high-precision gas flow sensors that meet the requirements are still under development. Therefore, the gas flow sensor has become a product that has been steadily developed and has great prospects.

Precautions for the use of gas sensors – ifm
Amperometric gas sensors operate by reacting with the measured gas and generating an electrical signal proportional to the gas concentration. A typical amperometric gas sensor consists of a sensing electrode (or working electrode) and a counter electrode, separated by a thin electrolytic layer.
The gas passes through a porous membrane ...

Precautions for the installation of high-frequency pressure sensors – ifm
The depth of the internal thread of the installation with the sensor should be greater than the length of the external thread of the sensor itself, so as to avoid the sensitive diaphragm of the sensor pushing to the bottom of the internal thread, so that the sensor is affected by stress.
If the size of the internal thread has been ...

Choice of pressure sensor – ifm
The first step in selecting a pressure sensor is to determine the pressure to be measured. Exciter sensors are divided into mechanical pressure and pneumatic pressure (hydraulic). The mechanical pressure unit is generally N.KN.KGF, etc. The pneumatic and hydraulic units are generally KPA, MPa, PSI, etc. This article describes the selection of mechanical pressures.

Signal discrimination method generated by vibration sensors – ifm
1. Distinguish according to the gap voltage
The oscillation sensor outputs a voltage signal that contains both DC and AC. The amount of DC corresponds to the uniform distance between the sensor and the probe, also known as the void voltage. The traffic corresponds to the oscillating signal. If the void voltage is normal, the alternating current is usually normal.
