A vacuum gauge measures the pressure in a vacuum. Vacuum gauges are a crucial component of instrumentation in a wide range of commercial and industrial applications, such as measuring pressure in heat pumps, air conditioning, and refrigeration systems. There are three types of vacuum gauges based on their operating method: mechanical, thermal conductivity, and ionization.
A wide variety of systems operating under vacuum rely on vacuum gauges to ensure consistent, effective, and safe operation. Measuring the vacuum in a given system provides valuable insights into potential maintenance or repair issues and also helps maintain efficiency.
Vacuum gauges are generally used in situations where the pressure in a system is lower than atmospheric pressure. It’s important to note that vacuum gauges typically display results as a negative number. Rather than using absolute pressure as a measurement, most vacuum gauges use relative pressure.
