If you are looking for a reliable and robust solution for an industrial point level sensing application; optical liquid level sensors may be the answer to your problems. Optical liquid level sensors are solid-state, meaning they have no moving parts to cause unreliability. They use infra-red light and can be used in environments where a traditional float switch would not be suitable.
Optical liquid level sensors do not measure the liquid level, instead, they detect the presence or absence of liquid. Optical liquid level sensors consist of two main parts; An infra-red LED and phototransistor that is accurately positioned at the base of the sensor tip. When the tip is in air, infra-red light reflects internally around the tip of the phototransistor providing strong optical coupling between the two. When the sensor tip is immersed in liquid, the infra-red light escapes from the tip causing a reduction in the amount of light at the phototransistor which makes the output change state.
The main selling points for an optical liquid level sensor is their compact size, their solid-state design, their low cost, and reliability. However, while extremely accurate for point level sensing in high pressure, temperature and at times corrosive environments; they are less useful for continuous level measurement applications.
