Optical liquid level sensor how it works
WebThese sensors actively discern between the liquid and gas states along a continuous fiber and can accurately pinpoint the liquid level. How It Works The technology uses a resistive heater wire bundled with the optical fiber. The heater is pulsed to induce a local temperature change along the fiber, and the fiber Bragg grating data is used to ... WebNov 9, 2024 · Optical Liquid Level Sensors They use an infra-red LED and phototransistor which are optically coupled when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. These sensors can detect the presence or absence of almost any liquid. Which sensor can detect liquid?
