Iranian Researchers Make 3D Nanometer Surface Gauge
“This device operates based on the phenomenon of interference in two modes of white light microscopic interferometry and phase shift and is capable of measuring the shape and roughness of surfaces with nanometer-level accuracy,” said Ehsan Ahadi Akhlaqi, the managing director of the knowledge-based company.
“One of the key features of this device is that, by working with an optical approach, it is completely non-destructive and does not cause any damage to the sample under test,” he added.
“The nanometer surface gauge has a higher data acquisition speed and offers a wider field of view. This device is also capable of measuring larger irregularities without reducing accuracy,” Ahadi Akhlaqi said.
He noted that due to the high level of technology used in the device, it is only produced in a few countries, including the US and Germany, adding that the Iranian scientists have also been able to make it.
In a relevant development in July, specialists of an Iranian knowledge-based company had also succeeded in reverse engineering and indigenization of the sensors for level gauges, one of the key equipment needed in the oil and gas industry.
“In a company active in the field of oil and gas, we reverse engineered one of the key equipment of the oil industry. The complex equations that were used in the design of this equipment required a combination of several different parameters to achieve a final result. Relying on the knowledge and expertise of our team, we managed to discover and solve these equations,” said Monireh Parsa, the managing director of the knowledge-based company.
“This equipment is a level gauge sensor that works by immersion and using a trig tube. As one of the methods of measuring the height of the fluid, unlike the buoyancy model, the submersion method is very complicated, but its low sensitivity to density and lack of influence from fluid vapors has made it one of the most widely-used methods in the oil, gas and petrochemical industries. The immersion sensor made by Shahrah Mechatronic Pars company is suitable for the market and application,” she added.
“This product has been manufactured for the first time in Iran and at present, it is used in refineries, petrochemicals and other industries,” Parsa noted.
