Heat treatment is a process used to change the microstructure of metals and other materials. This process usually requires temperature control and is sometimes done under atmospheric control. This atmospheric control is often applied to prevent unwanted chemical reactions or to achieve a certain surface finish. Vacuum is a common method used in atmospheric control.High Quality: Low vacuum levels can cause unwanted reactions such as unwanted oxidation or carburization on the surface of the material. Vacuum gauges can help prevent such defects.
Efficiency: It is necessary to know the vacuum level to know if the equipment is operating efficiently. If the vacuum is not working properly, this can cause the equipment or system to consume more energy.
Equipment Life: It is important to ensure that the vacuum is applied correctly to extend the life of the equipment. Incorrect vacuum levels can damage the equipment.
Safety: In some heat treatment processes, high vacuum levels can be dangerous. Therefore, ensuring that the vacuum is at the correct level is critical for safety.
There are various options among vacuum gauge types, such as Pirani vacuum gauges, ionization vacuum gauges and diaphragm vacuum gauges. However, vacuum gauges with SRG technology stand out for their resistance to high temperatures.
This measurement technology works by measuring the drift speed of a rotating rotor. The rotor is dragged by gas molecules in the vacuum, and this drift speed depends on the density of the gas.
Wide Measuring Range: SRG has the ability to measure over a wide vacuum range. This is advantageous in many heat treatment applications because there are often requirements for operating at different vacuum levels.
High Accuracy: SRG technology can measure with high accuracy even in ultra-high vacuum regions. High vacuum regions are a critical factor for achieving the best results during heat treatment.
Insensitivity to Gas Type: Unlike many other vacuum gauge technologies, the measurement accuracy of SRG is not dependent on the type of gas. This allows consistent measurements to be obtained when working with different gases.
Low Maintenance Requirement: SRGs are generally durable and have low maintenance requirements, providing long-term cost savings.
Unaffected by Contamination: Spinning rotor gauge technology is not easily affected by contamination or gas residues. It offers the advantage of being able to obtain accurate measurements even in dense gas atmospheres generated during heat treatment.
Simple and Direct Measurement: SRG technology is based on simple physical principles and calibration requirements are lower than other technologies. This means ease and reliability for the user.
In heat treatment applications, maintaining the correct vacuum levels is critical to optimize material properties and ensure product quality. Therefore, using a reliable and precise vacuum measurement technology such as SRG offers great advantages for process control and quality assurance.
