Understanding Vacuum Measurement Ranges: From Rough to High Vacuum

Leave a Comment / Technical Deep Dive / By /

Introduction Vacuum measurement ranges are the foundation of reliable process control in semiconductor manufacturing, physical vapor deposition (PVD), vacuum furnaces, and countless other industrial systems. Understanding where “rough,” “medium,” and “high” vacuum begin and end—and which gauge technology excels in each regime—helps engineers specify the right sensor the first time, avoid costly crossover errors, and […]

Pirani vs Cold Cathode Vacuum Gauge: How to Choose the Right One

Leave a Comment / Product Selection Guide / By /

Introduction Vacuum gauges are the eyes of any vacuum system. Selecting the wrong sensor can lead to inaccurate process control, extended pump-down times, or premature equipment failure. Two of the most widely used technologies—Pirani thermal conductivity gauges and cold cathode ionization gauges—cover the majority of industrial high-vacuum applications from 10−3 Torr down to 10−7 Torr.

Introduction to Vacuum Measurement Vacuum measurement is the process of determining the pressure exerted by residual gas molecules inside a sealed system below standard atmospheric pressure (760 Torr). Accurate vacuum readings are essential for process repeatability, product quality, equipment longevity, and personnel safety across a wide range of industrial applications. Without reliable pressure data, contamination
