Vacuum pressure gauge introduction

Vacuum compound pressure gauge is also known as compound gauges, these measure both pressure and vacuum. Use them with pumps, filters, regulators, compressors, and in suction and process lines.


Gauges with ABS plastic case are more corrosion resistant than gauges with steel case. Gauges with steel case are more impact resistant than gauges with ABS plastic case.


Vacuum pressure gauge Feature

  • The main parts, sheath, connection header, core, spring elements, etc. are made up of stainless steel material. So they are not only handsome but cauterization-resisting.

  • By using a bayonet to connect the cover and the case, the oil-filled gauge has reliable seal performance.

  • It has a reasonable design and reliable production process, so it owns ascendant vibration-resisting performance.


FAQ


How is vacuum pressure measured?

The most common device to measure vacuum pressure is a bourdon style manometer.


What is the difference between gauge pressure and vacuum pressure?

Gauge pressure and vacuum pressure are both measured relative to the atmospheric pressure. The difference is that gauge pressure is higher than atmospheric pressure, while vacuum pressure is lower than the atmospheric pressure.


Is vacuum positive or negative pressure?

Vacuum pressure is usually expressed with a negative number. It is measured with respect to the atmospheric pressure.

Vacuum pressure gauge application


Practically all industries make use of vacuum, from pick and place in the automotive industry, food & beverage, manufacturing, pharmaceutical, chemical, nautical, etc. The vacuum gauges are important devices to ensure optimal performance and safety of the system. They may be used for pick-and-place applications, keeping the workplace clean from pollutants, transport materials, etc.
