I. Working principle

The main sensing element of the air pressure sensor is a thin film sensitive to air pressure, which is connected to a flexible resistor. When the pressure of the gas being measured decreases or increases, the film deforms and the resistance of the resistor changes. The resistance of the resistor changes. The voltage measured at both ends will also change, and will be accepted by the data collector after A/D conversion, and then the data collector will transmit the results to the computer in an appropriate form.

IV.Typical applications

Air pressure sensors can be used to measure air pressure in containers and the surrounding environment. It is mainly suitable for physics experiments related to gas pressure, such as gas laws, etc. It can also be used to measure dry, non-corrosive gas pressure in biology and chemistry experiments. Its typical applications are: atmospheric pressure, ideal gas law, etc.

V.Caution

This product is suitable for educational use only and is not suitable for industrial, medical, research, or commercial applications.

VI.Usage Tips

1. During use, keep the container of the gas being measured tightly connected to the hose of the pressure measurement port of the sensor.
2. It cannot be used to measure liquid pressure. Please do not use it beyond the range.
