Vacuum gauge display during pump-down process

Why Your Vacuum Gauge Shows Pressure Plateau During Pump-Down

Leave a Comment / Maintenance & Troubleshooting / By /

Defining the Plateau Phenomenon in Vacuum Pump-Down During a typical vacuum pump-down cycle in systems like mass spectrometers, scanning electron microscopes, or heat-treatment furnaces, pressure initially drops exponentially as the pump evacuates bulk gas. However, engineers often observe a “plateau”—a region where the pressure decline flattens or halts temporarily, as indicated by stable readings on

Vacuum Gauge Selection for Vacuum Heat Treatment Processes

Leave a Comment / Industry Applications / By /

Vacuum Gauge Selection for Vacuum Heat Treatment Processes Vacuum heat treatment—encompassing annealing, tempering, brazing, and sintering—relies on precise pressure control to eliminate oxidation, decarburization, and hydrogen embrittlement while achieving uniform metallurgical properties. Incorrect vacuum levels during critical stages can ruin entire batches, leading to costly rework or scrap. The VG-SP205 Pirani Vacuum Transmitter and VG-SM225
