Vacuum gauges

A vacuum gauge is used to measure negative pressure, which is pressure below atmospheric pressure. The scale on this gauge is always negative and ends at zero.

At EMVO Techniek, you’ll find a complete range of vacuum gauges: with or without glycerine, digital or analog, and with or without options for panel mounting. Browse the different categories in our menu to find the vacuum gauge you need. Need advice? Our service desk is happy to assist you!

Complete range, large stock of vacuum gauges

EMVO Techniek works closely with all leading European manufacturers of pressure gauges. For every situation, we can select the best vacuum gauge for you. Additionally, we can deliver quickly as we always maintain a well-stocked inventory. Do you have special requirements, or is a standard gauge not suitable for you? We can modify the vacuum gauge in our workshop to meet your needs. Some examples of (digital) vacuum gauges available from us include:

• Type ETD 03 / class 0.1;
• Type ETD 04 / class 0.05.

How does a vacuum gauge work?

When measuring vacuum pressure, atmospheric pressure is the reference point. This is the standard pressure at sea level. Vacuum pressure is expressed in negative values, where -1 barg, or -15 psig, indicates a full vacuum. Please note: Atmospheric pressure is not the same as absolute pressure. Absolute pressure is measured from absolute zero, which is lower than atmospheric pressure. Would you like to know how a pressure gauge works? We explain it on this page.

Which vacuum gauge do you need?

Of course, you want to be sure you’re buying the right vacuum gauge. We’re here to help you make the right choice. The gauge you need depends on several factors, including:

• Accuracy
  The accuracy of our vacuum gauges varies. If you buy one with Class 1.0, the instrument has a maximum deviation of 1% of the scale range. The class you need depends on your situation and application.
• Scale and range
  A vacuum gauge has a negative scale because it measures pressure below atmospheric pressure. A full vacuum is indicated by -1 barg, or -15 psig. Differential pressure is expressed in bar Gauge (barg), while absolute pressure is expressed in bar. The same applies to Psi (pounds per square inch, commonly used in the US): the G in PSI stands for Gauge.
• Connection
  In most cases, vacuum gauges are equipped with a four- or six-sided connection nipple. To mount the gauge, you’ll need an appropriate wrench.

Applications of vacuum gauges

Vacuum gauges are used across many industries. They are commonly used in vacuum packaging in the packaging industry, as well as in warehouses and assembly lines where vacuum systems are employed. The so-called Pick & Place technique is based on vacuum and is used in robots and machines that pick up, move, and place products. These machines are found in the automotive industry as well as in factories producing microchips.
