A manometer is a device designed to measure pressure. Unlike a barometer, a manometer measures pressure in relation to another value. Glycerin pressure gauges are commonly used in industrial applications, including compressed air installations. We will tell what a glycerin manometer is used for in this article.
What is a pressure gauge?
The pressure gauge is used not only to measure the pressure, but also to maintain it at the expected level. Glycerine pressure gauges are used in compressors, pumps, hydraulic and cooling systems in industrial installations. Moreover, they are also used in the gas and heating industries, as well as in controlling water flow and pressure in pipes.
Glycerin plays a key role in manometers, allowing the measurement of pressure relative to atmospheric pressure, which is visible on the device as a zero value. Glycerine manometers indicate pressure higher than atmospheric. The pressure is read by deflecting the Bourdon tube and the degree of deflection indicates the pressure level.
Glycerine pressure gauges are mounted on devices using threads. Back, side or bottom threads are common. It is also possible to use a glycerine panel pressure gauge with desktop mounting.
What are the advantages of a glycerin pressure gauge?
Glycerine is responsible for the unique properties of the pressure gauge, which, thanks to its density, eliminates vibrations and vibrations, thus ensuring a stabilized pressure measurement. The lack of vibrations also extends the life of the device. Glycerine pressure gauges are resistant to large pressure differences in the system, so they are perfect for systems characterized by high pressure and dynamics.
How to choose the right glycerin manometer?
To properly select a glycerine pressure gauge for a compressed air system, several parameters should be taken into account. This will allow you to get the correct measurements. One of the parameters that should be taken into account is the air temperature and the compressor's operating environment. Glycerine manometers can be used to measure pressure in systems using compressed air at a temperature of up to 60 degrees Celsius. The operating pressure is also important - each glycerine manometer works in a specific pressure range. The devices also have an accuracy class. In the case of glycerin pressure gauges for compressors, devices of class 1.0, 1.6 or 2.5 are used.
Since glycerine pressure gauges are threaded on the compressor, the size and diameter of the thread and the way in which the measuring device should be mounted are also important. It is also worth taking into account the environmental conditions in which the pressure gauge will operate. Compressors may operate in aggressive or corrosive environments, therefore measuring devices may require an appropriate protective casing - brass or stainless steel.
In what industries are glycerin pressure gauges used?
This type of measuring devices is successfully used in pneumatic systems. They are used in medium preparation stations, compressed air reducers and filtering and reduction systems.
Glycerin pressure gauges, apart from compressed air systems, are used in a wide range of industries related to the chemical, pharmaceutical and machinery industries. They will also be indispensable in the energy and heating industry, hydraulic and construction devices and the machinery industry.
