The infrared water level sensor FS-IR1902 theory is optical. It is suitable for steam microwave ovens, coffee machines, water purifiers, etc., which require water tanks to automatically add water. FS-IR1902 optical level sensor has a fast reaction speed, the liquid level control accurate is high, the accurate is within ±1 mm, the repeatability is also extremely high. The photoelectric liquid level sensor can be installed up, down, oblique and sideways, and can be used after being installed without the characteristics of debugging and verification.
1)Solid state so no moving parts to cause unreliability.
2)Small in size so they can be installed in applications where space is limited.
3)Can detect tiny amounts of liquid when positioned correctly, ideal for leak detection.
4)Fast response time.
5)Repeatable sensing point.
6)Very robust permitting use in a wide range of fluids and chemicals.
