█ CLOSED ULTRASONIC SENSOR'S APPLICATION
Closed ultrasonic sensors are mainly used for reversing radar, liquid level detection, proximity switches, etc. Due to their good sealing, they can prevent the intrusion of dew, rain and dust, and can be used in dusty, humid and other harsh environments. It is called a waterproof ultrasonic sensor. The sensor is a gas medium sensor that has the advantages of small size, light weight, high sensitivity, and low power consumption, but this type cannot be immersed in a liquid. If you need an immersion, please contact us to choose a soda model that can be immersed in a liquid.
