Similarly, there are also Capsule Vacumetros that utilize two thin metal capsules bonded together with one end sealed. The change in pressure causes these capsules to expand or contract and this movement is converted into a readable value.

These mechanical vacumetros offer reliable measurements within their respective ranges and can be used for various applications such as industrial processes, scientific research, and even household maintenance tasks. They provide valuable information about vacuum levels to ensure efficient operation of systems and equipment.

Understanding how these mechanical vacumetros work helps us appreciate their importance in maintaining optimal vacuum conditions for different purposes.

The Bourdon Tube Vacumetro

The Bourdon Tube Vacumetro is a type of mechanical vacumetro that is widely used for measuring vacuum levels. It consists of a curved tube made from elastic materials such as brass or stainless steel. When subjected to pressure changes, the tube deforms and moves an attached pointer to indicate the corresponding vacuum level.

This type of vacumetro relies on the principle of elasticity. As the vacuum level decreases, the pressure difference between the atmosphere and the vacuum chamber causes the tube to expand or contract accordingly. The movement of the tube is converted into linear motion by a system of gears and levers, which in turn rotates the pointer on a dial.

One advantage of using Bourdon Tube Vacumetros is their simplicity and reliability. They are relatively inexpensive compared to other types and can withstand high pressures without being damaged. However, they may not be suitable for measuring very low vacuum levels due to limitations in sensitivity.

It’s worth noting that there are variations in design among Bourdon Tube Vacumetros depending on specific applications and requirements. For example, some models employ additional mechanisms like bellows or multiple tubes for improved accuracy or extended range capabilities.

The capsule vacumetro offers precise measurements within low-pressure ranges but requires careful consideration when used in conditions involving temperature fluctuations or high pressures

The Thermal Vacumetros

The Thermal Vacumetros are another type of vacumetro that rely on the principles of thermal conductivity to measure vacuum levels. These devices use a heated element, such as a thermocouple or a thermistor, to determine the rate at which heat is transferred from the element to the surrounding gas molecules.

When there is no gas present in the chamber being measured, heat transfer occurs primarily through conduction between the heated element and its support structure. As gas molecules enter the chamber, they collide with and absorb some of this heat energy, reducing its transfer rate. By monitoring changes in temperature or resistance caused by these collisions, thermal vacumetros can accurately gauge vacuum pressure.

Thermocouple vacumetros utilize two dissimilar metals joined together as an electrical circuit. The temperature difference generated when current flows through this circuit provides a measurement of vacuum levels.

On the other hand, thermistor vacumetros consist of a resistor whose electrical resistance varies with temperature. This change in resistance can be converted into an accurate reading of vacuum pressure.

Both types have their advantages and limitations but offer reliable solutions for measuring vacuum levels in various applications across industries such as manufacturing, research laboratories, and medical facilities.

This vacumetro consists of a heated wire filament placed inside a glass or metal tube. When exposed to gas molecules, the heat from the filament is transferred to these molecules through collisions, causing a decrease in its temperature. The change in temperature is then measured and used to determine the pressure inside the vacuum system.

One advantage of using a Pirani Vacumetro is its wide measurement range. It can accurately measure pressures ranging from atmospheric pressure down to low vacuum levels. Additionally, it provides fast response times and has good repeatability.

However, like other thermal-based vacumetros, it is influenced by gas composition and requires calibration for different gases. Also, it cannot measure pressures below certain levels due to limitations with heat transfer at high vacuum conditions.

Despite these limitations, the Pirani Vacumetro remains popular due to its simplicity, reliability, and cost-effectiveness. It finds applications in various fields such as semiconductor manufacturing, research laboratories, and industrial processes where accurate vacuum measurements are crucial for optimal performance.
