Introduction An important type of photodetector is the photovoltaic cell, which generates a voltage that is proportional to the incident EM radiation intensity. These sensors are called photovoltaic cells because of their voltage-generating capacity, but the cells actually convert EM energy into electrical energy. Photovoltaic cells are very important in instrumentation and control applications because …
What is a Geiger Muller? The Geiger-Müller tube or the G-M tube is the sensor element of the Geiger counter instrument used for the detection of ionizing radiation.Hans Geiger developed the device in 1908.In 1928, Geiger and Walther Muller improved the GEIGER MULLER COUNTER so that it could detect more types of ionizing radiation,Particle detector that measures ionizing radiation.The particles are usually beta and …
Introduction The infrared (IR) Gas detection method is based on the absorption of infrared radiation at specific wavelengths as it passes through a volume of gas. Typically, two infrared light sources and one infrared light detector measure the intensity of two different wavelengths, one at the absorption wavelength and one outside the absorption wavelength. If …
