What are the applications and advantages of pressure gauges?

A pressure gauge is an instrument used to measure fluid pressure and is widely used in industry, scientific research, medical treatment and daily life.

Application areas:

1. Industrial production: In the chemical, petroleum, natural gas, electric power, metallurgy and other industries, pressure gauges are used to monitor and control the pressure in the production process to ensure the safe operation of equipment.

2. Scientific research experiments: In experiments in physics, chemistry, materials science and other fields, pressure gauges are used to accurately measure the pressure changes in the experiment process and obtain experimental data.

3. Medical health: In the medical field, a sphygmomanometer is a common pressure gauge used to measure human blood pressure and help doctors diagnose and treat cardiovascular diseases.

4. Environmental monitoring: In environmental monitoring, pressure gauges can be used to measure atmospheric pressure, water pressure, etc., and provide data support for weather forecasts, hydrological monitoring, etc.

5. Transportation: In vehicles such as cars, airplanes, and ships, pressure gauges are used to monitor tire pressure, engine pressure, etc. to ensure driving safety.

6. Construction: In construction, pressure gauges are used to monitor the pressure in the process of concrete pouring, pneumatic tools, etc. to ensure construction quality and safety.

7. In daily life: In the home, pressure gauges can be used to monitor the pressure of gas pipelines, water heaters and other equipment to prevent safety accidents such as leakage and explosion.
