工業(yè)不銹鋼光學(xué)液位傳感器LLM19SC24P。

?  應(yīng)用鄰域  / Application
1.  水塔水位監(jiān)測(cè)  /   Water tower water level monitoring
2.  液位控制設(shè)備  /  Liquid level control equipment
3.  漏液保護(hù)設(shè)備  / Leakage protection equipmen t
4.  缺液保護(hù)設(shè)備  /  Lack of liquid protection equipment
5.  帶水箱的產(chǎn)品  /  Products with water tank
6.  熱水器/  Water heater
熱水器中沒有液體，則做停止加熱處理
If there is no liquid in the water heater, do stop heating treatment
7.  水族設(shè)備  /  Aquarium equipment
可配合遠(yuǎn)程設(shè)備或者其他設(shè)備，實(shí)時(shí)監(jiān)測(cè)魚缸里面的液位是否正常，例如在低水位監(jiān)測(cè)點(diǎn)安裝傳感器，若水位到達(dá)此點(diǎn)則提示，或在高液位監(jiān)測(cè)點(diǎn)，水位超過則 提示，以確保魚缸水位不會(huì)過低過高。
It can work with remote devices or other devices to monitor whether the water level in the aquarium is normal in real time. For example, a sensor is installed at the low water level monitoring point to prompt if the water level reaches this point, or at the high water level monitoring point to prompt if the water level exceeds this point, so as to ensure that the water level of the aquarium is not too low or too high.
8.  適用于環(huán)境嚴(yán)苛的設(shè)備，高溫/高壓環(huán)境下監(jiān)測(cè)水位
It is suitable for equipment with harsh environment, and monitors water level in high-temperature/high-pressure environment
?  原理與優(yōu)勢(shì)/ Principle and Advantages
1.  光學(xué)式液體傳感器的原理/  The principle of optical liquid sensors傳感器利用光電效應(yīng)和光的棱鏡的折射效應(yīng)進(jìn)行檢測(cè)容器內(nèi)是否有液體的存
在，當(dāng)容器內(nèi)有液體時(shí)，傳感器的紅外發(fā)光源發(fā)出的光照射到棱鏡上，由于棱鏡的折射率和液體相似，不會(huì)或有少量的紅外光被反射回來。當(dāng)容器內(nèi)沒有液體，傳感器的紅外發(fā)光源發(fā)出的光照射到棱鏡上，會(huì)進(jìn)行反射光電二極管接收到紅外光后，阻值發(fā)生改變，從而使電路中的電壓隨發(fā)生改變
The sensor uses the photoelectric effect and the refraction effect of the prism of light to detect whether there is liquid in the container, when there is liquid in the container, the light emitted by the infrared light source of the sensor irradiates the 
prism, because the refractive index of the prism is similar to that of the liquid, there will be no or a small amount of infrared light reflected back. When there is no liquid in the container, the light emitted by the sensor's infrared light source hits the prism, and the photodiode receives the infrared light, and the resistance value changes, so that the voltage in the circuit changes
