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.
Can replace magnetic float level switch
Standard size thread, the process is more refined.
Convenient installation, can be used according to differenct requirements.
This M14 Thread Water Level Detector Sensor can be used to monitor liquid level in watering machine, water heater, solar energy, air conditioner, vending machine, hot and cold water dispenser, Humidifier, dehumidifier, fluid control, a pump, alarm device, moisturizing machine , bathroom utensil , oil tank , water tower and chemical industrial ,etc. And widely applied in motor vehicles, industrial equipment, agricultural equipment and household electrical appliances in the future.
