Flush-mount pressure gauge 612.20 Stainless steel housing, 0 kPa-6 kPa, M20 x 1.5, Ø 100mm 31162341

Precise measurement of low pressures in industry

The capsule pressure gauge model 612.20 is a specialized measuring device designed for monitoring low pressures in industrial applications. Thanks to the proven capsule system and robust stainless steel construction, it ensures accurate measurements in the range 0-6 kPa while maintaining an accuracy class of 1.6.

Construction and materials for demanding applications

The 100 mm diameter housing made of chromium-nickel steel (CrNi) guarantees corrosion resistance and long-term operation in harsh industrial conditions. Protection class IP54 allows installation outdoors and in environments with elevated humidity. The measuring system based on a copper alloy element ensures stable readings and resistance to vibrations.

The twist-type cover made of stainless steel facilitates servicing and calibration of the device without the need to disconnect it from the installation. An industrial glass window protects the mechanism against mechanical damage while ensuring excellent readability of the indications.

Professional applications and operating parameters

The process connection M20 x 1.5 with bottom mounting enables easy installation in gas systems. The gauge is specifically designed for dry and non-aggressive gaseous media - ideal for filter monitoring, content control, and laboratory and environmental applications.

The internal mechanism made of copper alloy transmits the deformation of the Bourdon tube proportionally to the applied pressure onto the pointer. Zero-point adjustment available from the front of the dial enables quick calibration without compromising the housing seal.

Compliance with standards and operating conditions

The device meets the requirements of standard EN 837-3, confirming its suitability for precise measurements in industrial applications. The white aluminum scale with black markings and a black pointer ensure excellent readability even in low light conditions.

The operating temperature range is adapted to standard industrial conditions, and the robust construction minimizes the influence of vibrations on measurement accuracy. This model performs particularly well in monitoring ventilation systems, controlling pressure in gas installations, and applications requiring stable readings at low pressure ranges.
