Stainless steel pressure gauges

Stainless steel pressure gauge - Robust pressure measurement for demanding applications

Stainless steel pressure gauges are considered to be particularly durable and resistant. They are indispensable for pressure measurements in aggressive gases and liquids. At FILCOM, not only are the housings of our stainless steel pressure gauges made of corrosion-resistant chrome-nickel steel, but the process connection, the measuring unit and the pointer mechanism are also made of stainless steel. Our stainless steel Bourdon tube pressure gauges are therefore suitable for measuring the pressure of all gaseous and liquid media, with the exception of highly viscous and crystallizing substances. While measuring instruments with copper alloys are often damaged by aggressive media, our stainless steel pressure gauges offer the perfect solution, as they can withstand even the harshest conditions and offer an excellent price-performance ratio.

Scales and connection variants

Our stainless steel pressure gauges are available with single scales in bar as well as with double scales in bar and psi (1 bar corresponds to 14.504 psi). You can also choose between different connection configurations: The stainless steel connection threads are either positioned radially on the housing or axially on the back of the housing.

Safety levels according to EN 837-2

The user standard EN 837-2 defines specific safety levels for pressure gauge housings to ensure operational safety and the protection of people in the vicinity of the measuring point. Our range also includes safety versions of stainless steel pressure gauges with a break-proof front panel. In addition, pressure relief is integrated into the back of the pressure gauges, making them particularly suitable for use with aggressive media.

Quality class and accuracy

The accuracy class, which indicates the permissible deviation from the full scale value as a percentage, is indicated on the dial of each pressure gauge. For stainless steel pressure gauges, for example, the permissible deviation is 1.6 percent. This means that for a measuring range of 0 to 100 bar, the permissible deviation is 1.6 bar. In comparison, the maximum deviation for simple plastic pressure gauges can be significantly higher, for example 4 percent.

Choosing the right stainless steel manometer

Select the measuring range of your stainless steel pressure gauge so that the operating pressure is in the middle third of the display range. No special safety requirements apply to harmless media with a pressure below 25 bar. Stainless steel pressure gauges are indispensable when measuring the pressure of aggressive media. Safety models with break-proof front and rear pressure relief offer maximum protection.
