Pipeline water non contact tube liquid level sensor
FS-IR2023 level sensor is non-contact type, it is used for tube. The principle is infrared, output signal is analog.
When there is no water, the sensor outputs low voltage value; When there is water, the sensor outputs a high voltage signal.
The size can be customized.
The photoelectric liquid level switch uses the principle of optical reflection to measure,
the performance of level sensor will be affected when it is exposed to direct sunlight or other infrared interference.
Adjust the mounting angle or use a hood to avoid it.
