Photodiodes are highly advantageous for liquid-level sensing applications. Optical monitoring of fluid levels has many distinct advantages, mainly due to its ability to isolate the sensing process from the actual monitored material with no moving parts.
In industrial applications, keeping the monitoring system isolated allows the sensor to be separated from harsh chemicals or fuels. Mechanical systems are subject to corrosion and wear from contact with chemicals, risking system failure, and subsequent need for invasive removal and replacement of the level sensor. Optical sensors can be placed outside the fluid vessel and can easily be replaced in rare cases of failure.
Optical level sensors are also ideal for laboratory and pharmaceutical applications, as they eliminate the risk of contamination to highly sensitive instrumentation and analysis equipment.
Optical level sensors can be designed as simple high/low limit indicators or linear arrays of photodiode detectors to measure liquid levels with precise electronic readouts accurately.
