Review LEYBOLD Oerlikon Penningvac Cold Cathode Ionization Vacuum Gauge Head

The Leybold 171-D Oerlikon Penning Vac PR35 Cathode Ionization Vacuum Gauge Head is a high-performance and precision instrument designed for measuring vacuum levels in various industrial applications. This gauge head, manufactured by Leybold, a renowned name in the vacuum technology industry, and Oerlikon Balzers, a global leader in surface engineering, offers superior accuracy and reliability.

The 171-D model is part of the Penning Ion Gauge (PIG) series, which is known for its ability to measure low vacuum levels down to 10e-3 Pa (0.01 mbar). The PR35 variant is particularly suited for use in high-pumping speed vacuum systems due to its robust design and fast response time.

The cathode ionization gauge head features a cylindrical shape with a diameter of approximately 35 mm and a length of around 65 mm. It is designed to be installed in the vacuum system's pressure tapping point, allowing it to accurately measure the pressure in the system. The gauge head is made of high-quality materials that ensure durability and resistance to harsh vacuum conditions.

The operating principle of the Leybold 171-D Oerlikon Penning Vac PR35 Cathode Ionization Vacuum Gauge Head is based on the Penning ionization gauge technology. In this technology, an electrically charged filament in the gauge head ionizes the residual gas molecules, which then emit electrons when they collide with the filament. The resulting electron current is proportional to the vacuum level, allowing for precise and reliable pressure measurements.

The gauge head is equipped with a built-in high-voltage supply unit, which generates the required voltage for ionization. The voltage can be easily adjusted using the external control knob or the integrated control panel. The gauge head also features a built-in temperature sensor, which ensures stable operation by monitoring the filament temperature and adjusting the voltage accordingly.

The Leybold 171-D Oerlikon Penning Vac PR35 Cathode Ionization Vacuum Gauge Head is designed for easy installation and maintenance. It comes with a threaded connection for quick and secure attachment to the vacuum system. The gauge head also has a transparent window, which allows for easy visual inspection of the filament and the ionization process.

The instrument offers excellent accuracy and repeatability, making it an ideal choice for applications that require precise vacuum level measurements. It is suitable for use in various industries, including semiconductor manufacturing, vacuum coating, vacuum drying, and scientific research.

In summary, the Leybold 171-D Oerlikon Penning Vac PR35 Cathode Ionization Vacuum Gauge Head is a high-performance and reliable instrument for measuring vacuum levels in industrial applications. Its robust design, fast response time, and easy installation make it a popular choice among vacuum system operators. With its superior accuracy and reliability, it enables users to optimize their vacuum processes and improve their overall productivity.
