Pressure

Mechanical Pressure Gauges

Relative Pressure

The relative pressure is measured in proportion to the surrounding air pressure. The surrounding air pressure corresponds to 0 bar. Positive values are obtained if the measured pressure is higher than the surrounding air pressure. Vice versa if the pressure is less than the atmospheric pressure negative values are obtained. Relative pressure measuring devices have only one pressure port, but always measure the pressure in relation to the surrounding air. The current atmospheric pressure is the reference for the zero point.

Standard

Standard manometers are pressure gauges with elastic measuring elements named Bourdon tubes that can be applied by pressures up to 400 bar. At higher pressures, spiral springs have their use in their respective areas. Using higher quality materials, the standard pressure gauge program was extended with Heavy Duty Pressure Gauges.

Higher Corrosion Resistance

Pressure gauges with higher corrosion resistance are used for pressure measurement of gaseous, solid and liquid, and corrosive media, also in aggressive environments, but not for highly viscous and non-crystallizing media.

Absolute Pressure Gauges

Absolute pressure gauges have only one pressure connection and measure always with respect to the absolute vacuum. They are always used when, particularly with measurement of low pressure or vacuum, influence from atmospheric air pressure fluctuations which could falsify measurements has to be ruled out. The design and materials are selected to allow the instruments to satisfy the stringent demands of the chemical industry. They are used with aggressive media (fluids) and/or in aggressive environments.

Differential Pressure

When differential pressure gauge the difference between two pressures is directly detected and displayed. All known measuring elements and measuring principles of the overpressure pressure gauges can be used.

Standard

At differential pressure gauges rotate two independent bourdon tube pressure elements around the same central axis, and show the pressures separated to an outer dial to another. They are for liquid or gaseous media suitable which not crystallize nor are highly viscous. They are used everywhere, where the resulting differential pressure to be displayed simultaneously.

Higher Corrosion Resistance

The use of high quality materials such as stainless steel makes the measuring system and the housing of the differential pressure gauges with higher corrosion resistance resistant against chemically aggressive media and ambient. In contrast to the Bourdon tube pressure differential devices, a membrane system is pressurized with different pressures, whereby a value who is displayed, which arose from the upstream and downstream pressure difference.
