It is distributed with the SIGMA-X software that fully controls the measurements. It automatically detects the appropriate range of airflow speeds and measures pressure drops in function of airflow speed to accurately compute the static airflow resistance, the static airflow resistivity, and the permeability. The system is based on direct method described in ASTM C522-03 and ISO 9053-91 standards.<\/p>\n<p>&nbsp;<\/p>\n<p>Material Properties<\/p>\n<p>\u25ba Static Airflow Resistivity (Pa.s \/ m\u00b2 veya rayls \/ m)<\/p>\n<p>\u25ba Static Airflow Resistance (Pa.s\/m or rayls)<\/p>\n<p>\u25ba Static Viscosity Permeability (m\u00b2 veya Darcy)<\/p>\n<p>&nbsp;<\/p>\n<p>Scope of application<\/p>\n<p>Mecanum\u2019s static airflow resistance meter is used by the world\u2019s leading material suppliers for both automotive and aircraft industry for quality control in the manufacturing process of materials; research, development, and innovation, and for feeding acoustical prediction software dealing with sound absorbing materials The main applications of static air flow resistance measurement systems are:<\/p>\n<p>\u25ba Quality control studies in materials manufacturing processes<\/p>\n<p>\u25ba Research, development and innovation<\/p>\n<p>\u25ba Adding material sound absorption properties to acoustic simulation software<\/p>\n<p>&nbsp;<\/p>\n<p>Key Features<\/p>\n<p>Mecanum static air flow resistance measurement systems; It comes with a test specimen insertion section, thin film section, stainless steel material, calibration material and calibration control card and Sigma-X \u2122 software that can be configured in different sizes. Sigma-X \u2122 software is used to obtain data from the tester and to process the resulting static air flow resistance data. The static air flow resistance measurement system works with disc-shaped calibration materials which can also be used in B&amp;K and Mecanum, impedance tubes, porosity measurement systems and semi-static mechanical analyzer systems. Optional calibration samples and material placement sections are also available.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sigma-Static Air Resistance Measurement Systems &nbsp; SIGMA is used to measure the airflow resistivity and permeability of permeable materials.
