What does the pressure difference of 18 pa mean?

The pressure difference of 18 pa means that the pressure difference is 18 Pascal. In environmental control and industrial production, it is often necessary to measure the pressure difference between two points of gas or liquid and the pressure values before and after. This pressure difference is usually used to measure air flow, liquid flow rate, pipeline pressure and filter performance. The pressure difference of 18 pa represents a physical index or parameter in a process or system for both mechanical engineers and thermal engineers.

The pressure difference of 18 pa has an important application in the field of air purification. For example, the indoor fresh air system needs to ensure the gas pressure balance between different rooms, which requires measuring the pressure difference in different areas. In addition, in medical environment, such as operating room, infection ward, etc., it is also necessary to forcibly control the air pressure difference to ensure that the air flow direction is isolated from the clean area. In chemical production, the pressure and flow in the reactor are controlled by the pressure difference of 18 pa to ensure the stability of the reaction and the quality of the finished product.

To measure the differential pressure of 18 pa, a differential pressure sensor or a pressure sensor is usually needed. These sensors can convert the pressure difference or pressure into corresponding electrical signals for the control system or personnel to read and analyze. There are many kinds of sensors for measuring differential pressure, such as differential pressure sensor, mass flowmeter and pressure transmitter. In practical application, using different types of sensors can effectively measure the pressure difference in different ranges to meet the needs of different scenarios. At the same time, we need to pay attention to the accuracy and response speed of the sensor to ensure the accuracy and real-time performance of the measured data.
