UVPP Application Field and Working Principle

Unipolar Vacuum Probe (UVPP) has been successfully used in many industries such as power engineering, mining, metallurgy, machinery, automotive, instrumentation, and marine engineering etc. UVPP is a new type of vacuum gauge, which uses radioactive electrons as the energy source. This radiation source is a low-energy beta source which emits electrons with an energy of up to 50 keV, making it possible to measure the pressure inside the measured container. The working principle of this probe is based on the emission of the electrons by the radioactive source, and their subsequent absorption in the container wall.

Application of UVPP

UVPP is widely applied in various vacuum systems since it can measure the pressure more precisely than other vacuum probes. As it works on the principle of absorption of radiation, it can work in extreme temperature and pressure conditions, and can even be used in aggressive environments such as high pressure steam, etc. Moreover, it does not require any separate power supply and thus is easy to install and maintain. UVPP is generally used to measure pressure in a wide range of industrial systems such as furnaces, boilers, pressure vessels, pumps, furnaces, engines, etc. In addition, it can also be used in laboratory and research applications.

Working Principle of UVPP

The working principle of a UVPP is based on the absorption of the radiation emitted by a radioactive element. The source of electron radiation is a beta particles, which are electrons with an energy of up to 50 keV. When these particles strike the wall of the container, they leave their traces in the form of tiny particles that accumulate in the container wall. As the pressure inside the container decreases, the number of beta particles absorbed also decreases. Consequently, the pressure inside the container can be determined by measuring the number of beta particles absorbed.

UVPP utilizes a special detector which is made up of semiconductor material and is capable of sending out electric signals when it receives radiation. This detector is placed near the container wall and the number of electric signals generated is proportional to the pressure inside the container. Thus, the pressure can be measured accurately using this device.

Advantages of UVPP

There are numerous advantages of using UVPP in comparison with other methods of measuring pressure. The main advantages are:

• High accuracy: UVPP can measure pressure with an accuracy of up to 0.01 mbar.
• Easy to install and maintain: UVPP does not require any external power supply and thus is easy to install and maintain.
• Wide range of application: UVPP can be used to measure pressure in extreme temperature and pressure conditions, making it ideal for many industrial applications.
• Long lifespan: UVPP can last for a very long time since it relies on a radioactive source which is extremely stable.

Conclusion

In summary, Unipolar Vacuum Probe (UVPP) is a new type of vacuum gauge which uses radiation source to measure the pressure inside the container. It is widely used in various industrial applications due to its accuracy and ease of installation and maintenance. It also has a long lifespan, making it a more cost-effective and reliable option for measuring pressure.
