The primary function of a vacuum gauge is to provide the measurement of vacuum pressures. There are many uses for these pressures, meaning there are many types of vacuum gauges too.

Sometimes, you encounter mysterious situations in the workshop. Maybe some measurements within a confined space seem off. You can’t quite pinpoint what’s wrong with your equipment or machinery.

A vacuum gauge then lets you measure pressure in a space. As a result, you can monitor the performance of your machinery.

So now, let’s get started with its applications of various types.

Thermocouple Gauge (T/C or TCG)

The way gases conduct heat is how a thermocouple gauge works. It is made up of two different metal lines that are joined at one end. When a voltage is put between the joints, heat is made, and the difference in temperature between the junctions depends on how well the gas transfers heat.

They are used a lot in vacuum technology, the manufacturing of semiconductors, and other vacuum systems where accuracy and dependability are very important. Thermocouple gauges are durable, easy to use, and can record a wide range of temperatures.

Capacitance Manometer

Capacitance manometers measure absolute pressure by detecting the change in capacitance between two wires that happens when pressure bends a diaphragm. Some modern capacitance manometers are wireless, which makes monitoring pressure easier and more advanced. A wireless micron vacuum gauge found here can be used to access and watch pressure measurements from a distance.

They are used a lot in vacuum systems, the manufacturing of semiconductors, analytical tools, and any other place where precise gauge pressure control and sensitivity are important. People like capacitance manometers because they are accurate, respond quickly, and stay stable over time.

Ionization Gauge

In the high vacuum and ultra-high vacuum (UHV) range, ionization gauges are used a lot. The way they work is called gas ionization, and it happens when an electron beam from a cathode hits gas molecules in a vacuum room and turns them into ions. An anode collects the ions that are made, and the ion current is recorded and linked to the vacuum pressure of the gas.

They are often used in ultrahigh-vacuum (UHV) studies, surface science, thin-film deposition, and any other situation where accurate and stable measurements of pressure at very low pressures are needed. People like ionization gauges because they are sensitive, don’t get dirty easily, and have a small effect on the vacuum system.

Cold Cathode Gauge

Cold cathode gauges are devices that measure pressure. They work by sending electrons away from a cold cathode. When a high voltage is applied to the cathode, electrons are released. When gas molecules come into touch with the electrons, they become ionized. The ions that are made are collected on an anode, and the pressure is measured by how fast the ions are moving.

They are often used in vacuum systems, industrial processes, and other places where they need to be tough and not get dirty. People like cold cathode gauges because they are reliable, use little power, and can work in difficult conditions.

Unlocking Secrets of Pressure with Vacuum Gauges

Vacuum gauges are versatile tools offering practical solutions in a variety of applications. Ultimately, the choice of gauge depends on your specific needs. Consider the accuracy, ease of use, and cost when selecting the right gauge for your environment.

With the right selection, you can achieve optimum performance and accuracy. Have questions? Contact a professional to learn more.
