Product Details

Product Introduction

The working principle of M14 Thread Water Level Detector Sensor is direct and simple. When the sensor is surrounded by air, the angle of incidence is greater than the critical angle and thus total reflection occurs. Totally reflected light will be transmitted to the receiver. Conversely, when the sensor is surrounded by liquid, due to the refractive index of the liquid and the sensor tip material, almost all light will penetrate the front of the sensor. Using this principle, the optical liquid level switch design is based on light. Mini electric optical level switch is widely used in level control and alarm of all kinds of industry such as electronic, electric power, chemical, water treatment, water supply and drainage due to its low price, reliable performance and flexible installation method.
