光电液位传感器高温款LLM12DH05-HT

应用邻域 / Application

1. 工业高温水位保护设备

此传感器可在-25-100摄氏度环境内持续工作

2. 水族设备 / Aquarium equipment

可配合远程设备或者其他设备，实时监测鱼缸里面的液位是否正常，例如在低水位监测点安装传感器，若水位到达此点则提示，或在高液位监测点，水位超过则提示，以确保鱼缸水位不会过低过高。

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.

3. 液位控制设备 / Liquid level control equipment

4. 漏液保护设备 /Leakage protection equipment

5. 缺液保护设备 / Lack of liquid protection equipment

6. 带水箱的产品 / Products with water tank

原理及优势/ Principle and Advantages

1. 光学式液体传感器的原理

传感器利用光电效应和光的棱镜的折射效应进行检测容器内是否有液体的存在，当容器内有液体时，传感器的红外发光源发出的光照射到棱镜上，由于棱镜的折射率和液体相似，不会或有少量的红外光被反射回来。当容器内没有液体，传感器的红外发光源发出的光照射到棱镜上，会进行反射光电二极管接收到红外光后，阻值发生改变，从而使电路中的电压随发生改变

2. 优势

1高温耐受性好，使用优质元器件，良好电路设计使温度漂移抑制好，可在100度的高温环境下持续运行
