WebMar 23, 2024 · Optical pressure sensors: Work by using the change in the refractive index of a material when subjected to pressure to measure pressure. These sensors are commonly used in medical and scientific applications , as they are able to provide accurate measurements without coming into contact with the fluid being measured .
WebThe sensing element for an optical DO sensor is an oxygen sensitive luminophore. A blue light from the sensor excites the luminophore. When the excited molecule returns to its ground state it gives off red light. In the presence of oxygen some of the energy is transferred to the oxygen molecule. chinese simmental beef cattleWebThe sensing principle employed by a sensor, can influence accuracy, reliability, measurement range, and compatibility with the target environment.
