1) Smallest size. Just need a small place to install the level sensor.
2) PTFE wires and Polysulfone housing. This level sensor can be used in high temperature and corrosion liquid.
3) Waterproof grade is IP 65.
4) Low cost.
We offer Economical Optical level switch for industry instruments,FS-IR02-P series, it has PSU housing and TEF wire, so this series level sensor will use high temperature (100 degree) and detect fuel oil level.
The optical level switch FS-IR02-P 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.
