Vacuum Gauge

Common Retrofit Challenges in Coating Machine Vacuum Systems Coating machines—whether for PVD, CVD, or optical thin-film deposition—rely on precise high-vacuum measurement to maintain repeatable process conditions. When retrofitting aging vacuum gauges, engineers face recurring obstacles: mismatched mechanical interfaces that require custom adapters, incompatible analog or digital signals that force PLC reprogramming, and the risk of

Measurement Principle Comparison Understanding the fundamental operating physics of vacuum gauges is essential for selecting the right instrument for high-vacuum applications. Cold cathode gauges, such as Poseidon Scientific’s VG-SM225, rely on the Penning discharge (or magnetron discharge) principle. A high voltage (typically −2000 V after startup at −2500 V) applied between a cylindrical anode and

Space Constraint Challenges in Small Compact Vacuum Systems Modern vacuum applications increasingly favor miniaturization. Benchtop mass spectrometers, portable residual gas analyzers, small-scale PVD chambers, electron microscopes, and compact vacuum heat-treatment fixtures all operate in tight footprints where every cubic centimeter counts. Traditional vacuum gauges from legacy suppliers often measure several inches in diameter and require
