What is a Baratron gauge?
Baratron capacitance manometers measure true pressure (defined as force/unit area). This means that the measurement is insensitive to the type of gas being measured. Other gauges, such as Pirani, thermocouple and ion gauges, do not measure true pressure and therefore their readings will be gas-type sensitive.
What is a Baratron?
The MKS a-Baratron® manometer is an advanced general purpose absolute heated capacitance manometer developed specifically for use in vacuum and pressure measurement applications where high accuracy and excellent repeatability are crucial to process success.
What is MKS Baratron?
MKS Baratron® capacitance manometers are highly accurate and repeatable, insensitive to gas composition, compact, and easily interfaced with most process tools. We manufacture our diaphragm gauges almost exclusively using nickel-based alloys such as Inconel®, Incoloy® and others.
What is a capacitance manometer?
A Capacitance Manometer is a pressure gauge used in the rough and high vacuum range. Capacitance Manometers are extremely accurate, typically 1% of scale. It is capable of measuring the absolute pressure or relative pressure, depending on the gauge model used.
What is Convectron gauge?
Overview. The Granville-Phillips® 275 Convectron® Pirani Vacuum Gauges have been the world-standard convection-enhanced Pirani gauge for over 35 years and are used in thousands of vacuum processes to accurately measure pressure from atmosphere to 10-4 Torr.
How does a Penning gauge work?
The standard type of ionization gauges is Penning gauages. The operation principle of penning gauge is similar to that of ion vacuum pump. The gas molecules in vacuum enter the gauge and move between two parallel electrical plates or tube-based anode and cathode biased at a DC voltage of 2,000 V.
What is Pirani vacuum gauge?
The traditional Pirani vacuum gauge, originally invented in 1906 by Marcello Stefano Pirani, is based on a hot metal wire suspended in a tube that is exposed to gas pressure media. The Pirani gauge measures the vacuum pressure dependent thermal conductivity from the heated wire to the surrounding gas.
What is the range of Penning gauge?
The Penning Gauge PEG100 has been designed for vacuum measurement of in the pressure range of 1×10-9 to 1×10-2 mbar.
