In this article, we will learn about vacuum meters, operating principles, types of vacuum meters, applications and uses, maintenance, prices and its importance in industries. Karma.
What is a vacuum meter?
A vacuum gauge is a vacuum pressure measuring device, used to measure pressures lower than atmospheric pressure. It is designed to measure pressure from 0 to 1 atmosphere (atmosphere), equivalent to 760 mmHg (millimeters of mercury). Vacuum gauges can be used to measure absolute vacuum pressure or relative vacuum pressure.
Vacuum gauges have two main components: a pressure sensor and a display unit. The pressure sensor is where pressure is measured and converted into an electronic signal. The display unit will display the pressure value in digital or analog format.
Operating principle of vacuum meter
Vacuum meters operate based on the Boyle-Mariotte principle, one of the basic principles of atmospheric physics. According to this principle, the pressure of a gas increases inversely with its volume. This means that as volume decreases, pressure increases and vice versa.
Vacuum gauges use a pressure sensor to measure vacuum pressure. This sensor consists of a tube and a moving part, usually a metal rod. When vacuum pressure acts on the duct, it causes the metal rod to move. This moving part will be connected to an electronic sensor, generating an electronic signal corresponding to the pressure value.
Types of vacuum watches
There are many different types of vacuum meters, used in different applications. Here are some common types of vacuum meters:
Mechanical vacuum watch
Mechanical vacuum gauges operate on the Boyle-Mariotte principle and use a pressure sensor to measure vacuum pressure. It can be used to measure relative pressure or absolute pressure. Mechanical vacuum gauges are typically highly accurate and are used in medical, scientific, and industrial applications.
Electronic vacuum meter
Electronic vacuum gauges use an electronic pressure sensor to measure vacuum pressure. It can be used to measure relative pressure or absolute pressure. Electronic vacuum gauges are typically more accurate than mechanical vacuum gauges and are used in medical, scientific, and industrial applications.
Digital vacuum meter
A digital it is a type of electronic vacuum meter, but has the added feature of displaying numbers on an LCD or LED screen. It can be used to measure relative pressure or absolute pressure and has high accuracy. Digital vacuum meters are commonly used in medical, scientific and industrial applications.
Application of vacuum meter
Vacuum meters have a wide variety of applications in everyday life and in various industries. Here are some common applications of vacuum meters:
Check and measure vacuum pressure
Vacuum gauges are used to test and measure the vacuum pressure of gas, liquid and solid systems. It can be used in industries such as automobile manufacturing, electronics, medical and many other industries.
Check and measure absolute pressure
Vacuum gauges can also be used to test and measure the absolute pressure of gas, liquid and solid systems. This is important in ensuring the safety and performance of equipment and machinery across industries.
Check and measure relative pressure
Vacuum gauges can also be used to test and measure the relative pressure of gas, liquid and solid systems. This can help identify pressure variations in systems and ensure their performance and safety.
Instructions for using vacuum meter
To use a vacuum meter effectively, you need to follow these steps:
Step 1: Prepare the device
Before using the vacuum meter, you need to check whether it has enough battery or not. If not, please replace the battery with a new one before use. You also need to check if the pressure sensor is damaged and replace it if necessary.
Step 2: Connect the vacuum meter to the system to be measured
After preparing the vacuum meter, you need to connect it to the system to be measured. This can be done using connecting pipes or valves.
Step 3: Adjust the vacuum meter
Before you start measuring, you need to adjust the vacuum meter to ensure its accuracy. This can be done by turning the pressure adjustment knob until the needle or display reaches zero.
Step 4: Measure pressure
Once you have adjusted the vacuum gauge, you can begin measuring pressure. Make sure that the system to be measured is turned on and operating normally. Then, read the pressure value on the vacuum gauge and record it.
Step 5: Turn off the vacuum meter
After completing the measurement, turn off the vacuum meter to save battery life and protect the device.
Maintenance of vacuum meters
To ensure the accuracy and longevity of your vacuum meter, you need to maintain it regularly. Here are some things you can do to maintain your vacuum meter:
Check and replace the battery
Batteries are an important power source for vacuum watches. Therefore, you need to check and replace the battery regularly to ensure the vacuum meter always works well.
Check and replace the pressure sensor
The pressure sensor is an important part of the vacuum meter. If it is damaged, the vacuum meter will not operate correctly. Therefore, you need to check and replace the pressure sensor when necessary.
Clean the vacuum meter
To ensure your vacuum meter always works well, you need to clean it regularly. Use a damp cloth to clean the surface of the vacuum meter and avoid contact with water or strong detergents.
