For 40 years now, EMVO Techniek has been a specialist in pressure gauges, thermometers and pressure measurement devices. We are both manufacturer and wholesaler. Do you wish to buy a pressure gauge? You will find in our product ranges both dry pressure gauges as well as glycerine pressure gauges. Our large warehouse disposes of sophisticated storage technologies, enabling us to maintain high stock levels at all times. You can be sure to find just the pressure gauge that you are looking for.
A pressure gauge can measure gas or liquid pressure within a closed space, such as for example a boiler or a cylinder. The most common pressure gauge is the aneroid gauge, based on a metallic pressure-sensing element. They are especially applied in central heating systems, although many other applications are possible, such as:
A dry pressure gauge is suitable for environments that do not cause condensation on the display glass, and where no vibrations or pressure surges occur. They are cheaper than the glycerine filled pressure gauges that are applied in more unstable and moist environments.
Pressure gauge functioning can be based on several different technologies. Aneroid gauges, also known as dry or mechanical gauges, are very common. Liquid based gauges use a liquid to measure the pressure. Glycerine is often used to that end.
A pressure-sensitive, elastic metal element is used in this type of gauges. The metal within the gauge wil deform due to pressure difference. This deformation is sensed and will be measured, which will cause the gauge needle to turn and indicate the pressure on it's scale.
We have a wide range of pressure gauges for dry application to offer. You can choose from pressure gauges:
Pressure gauges of this type are especially useful in situations where pressure surges, vibrations or other impacts frequently occur. These impacts will be absorbed by the liquid within the gauge, which will help preventing deterioration of you measuring instrument.
The most commonly used pressure gauge or manometer is the Bourdon pressure gauge. However, when the measured medium is corrosive, polluted, or viscous, the better option is a diaphragm pressure gauge. The diaphragm separates the medium from the pressure gauge mechanism, preventing it from damage caused by certain properties of the medium.
Accuracy is an important feature for your pressure gauge. The manometer class number tells you what accuracy it has: A dry pressure gauge class 1.0 has a maximum deviation of 1% on the reach of the scale. For example: when the maximum reach is 5 bars, deviation would be maximum 0.05 bar.
You can easily access all our pressure gauges through our website. Within all categories, a variety of types and versions are available.
