Description


The 24V liquid level sensor FS-IR1902 working theory is infrared, it judges whether there is liquid or no liquid at this position according to the reflection of light in two media. The two media are air and liquid. When the sensor head is exposed to the air, the light is directly reflected back to the receiver of the sensor. When the sensor head is immersed in the liquid, light will be refracted in the liquid, and only a little or no light will be reflected back to the receiver. The sensor judges to output different voltage signals according to these two states. After receiving the signal, the device controls the liquid level. For example, the pump starts to add water when the water is lower than the sensor head, and the pump stops adding water when the water is higher than the sensor head.


Advantages

1) The performance of optical level is less affected by external factory, such as the liquid density, color, temperature, pressure, corrosives, small impurities in the liquid and scale.

2) High reliability and sensitivity.

3) Simple installation way.

4) Resistance high temperature of 100 degree.

5) Resistance corrosion of oil, fuel, diesel and etc.

6) It can be used in high pressure storage tank.

Disadvantages

1) The tank need open a hole of about 11~14mm.

2) The circuit need to be changed if you used float level sensor before.

There are three wires of 24V liquid level sensor FS-IR1902, namely power line, ground line and signal line. Generally, each wire is distinguished by a different color, usually the power line is red, the ground line is blue, and the signal line is yellow. The following is the wiring circuit diagram of the photoelectric water level sensor of EPTSensor.
