Optical pressure sensor working

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. WebPressure sensors have been created that can be read optically (Abeysinghe et al., 2001, 2002; Hill et al., 2007; Ni et al., 2006; Xiaodong et al., 2006).Optical pressure sensors have potential applications for harsh environments.
