Pressure gauge dry application and panel mounting

Regarding pressure gauges, EMVO Techniek disposes of over 40 years of specialized experience. If you are looking for a dry pressure gauge for panel mounting, EMVO Techniek is all you need.

What is a pressure gauge

A pressure gauge is a tool to measure pressure, whether it is liquid, air, or gas pressure. Depending on the application, different technologies are used to measure with a pressure gauge.

Dry application

Dry pressure gauges, or aneroid or mechanical gauges, are most the most widely used. They are perfect for environments that do not suffer from any mechanical vibrations or pressure surges. They measure pressure using a pressure sensitive type of metal. Pressure will cause the metal to deform, which will be measured by the needle, indicating the exact pressure on the scale.

Bourdon

Most dry application pressure gauges are based on the Bourdon principle: pressure is measured by a little flattened C-shaped metal tube, usually made of brass. The tube is open on one side, where the medium can enter. When the medium pressurizes the inside of the tube, the C-shape is forced to change into a straighter form. That means that the other, closed end of the tube will start to move. This closed end is connected to a mechanism that amplifies the movement and passes it to an indicator needle in the display, which will rotate from left to right on a printed scale. When pressure decreases, the tube will regain its original shape and the needle will move back to its original position.

Diaphragm

Another option is the use of a diaphragm pressure gauge. The principle is the same: The metal diaphragm is deformed by pressure and converts that deformation in a movement of the indicator needle. A diaphragm manometer is used when corrosive or aggressive media are involved, but also in case of viscous media that do not enter easily into a Bourdon tube. The diaphragm separates the medium from the rest of the dry pressure gauge, so it cannot be damaged.

Liquid application

In case of a constant vibration, pressure surges or other impacts are possible, a liquid-filled pressure gauge is the best solution. Glycerine is a commonly used liquid to this end. It can absorb vibrations and shocks within the gauge and prevents deterioration.

Clearance on the display unit

When choosing the right pressure gauge, it is important to have in mind that the pressure to be measured does not exceed two thirds of the display scale. This way, there will always be room for clearance in case of abnormal deviations.

Panel mounting

Our dry pressure gauges for panel mounting have their outlet on the back side and feature special mounting holes that make them easy to assemble onto a panel.
