New Vision Sensor to Measure and Monitor Gas Pressure

The paper presents the construction and the use of a video sensor developed to measure air pressure. A characteristic feature of the device is pressure measurement based on digital image processing and self-diagnostics performed on the basis of an image. The paper presents the results of sensor calibration and measurements taken during the tests. It has been shown that the developed video-manometer model that is equipped with a at diaphragm allows measuring the air pressure in the range of 0 100 mbar with an error less than 2%.
