How to protect ultrasonic sensors from water erosion?
Protecting ultrasonic sensors from water erosion is an important maintenance measure, especially in underwater or humid environments. Here are some effective strategies and methods:
Choice of installation location
Avoid corners and container walls: Ultrasonic sensors should be avoided from being installed in the corners of containers or near the container walls, because these places are prone to strong reflections, resulting in measurement errors, and may also accelerate the erosion of water.
Stay away from the feed and discharge ports: Turbulence and bubbles during the feeding and discharging process may affect the propagation of ultrasonic signals, thereby indirectly affecting the durability of the sensor.
Consideration of environmental factors
Avoid high temperature and corrosive environments: Long-term exposure to these environments may damage the sensor. If it is unavoidable, a sensor with a corresponding protection level should be selected.
Prevent electromagnetic interference and acoustic interference: Electromagnetic interference and strong acoustic interference will affect the normal operation of ultrasonic sensors, and they should be avoided as much as possible in environments with strong electromagnetic fields or strong acoustic interference.
Proper installation and debugging
Vertical installation: Ultrasonic sensors should be installed vertically on the container to ensure that the ultrasonic signal propagates vertically downward to reduce reflections and interference.
Initial commissioning and regular calibration: After installation, initial commissioning should be performed to ensure that the sensor can measure accurately. Calibrate the sensor regularly to ensure long-term measurement accuracy.
Take protective measures
Choose the appropriate protection level: Choose the appropriate protection level according to the installation environment, such as IP65, IP67, etc., to protect the sensor from the influence of the external environment.
Install a sunshade (outdoor installation): When installed outdoors, it is recommended to install a sunshade to extend the service life of the ultrasonic sensor.
Regular inspection and maintenance: Regularly check the working status of the ultrasonic sensor, including the integrity of the cable, sensor and housing. Clean the sensor surface to ensure that there is no dirt and scale to ensure the effective propagation of the ultrasonic signal.
Selection of special materials
Anti-corrosion material probe: In an environment with corrosive gases, a probe made of anti-corrosion materials should be selected to prevent moisture and corrosive gases from eroding the sensor.
Grounding precautions
Separate grounding: The grounding of the ultrasonic sensor should be carried out separately, and avoid being connected to the grounding bar of the electrical cabinet to reduce interference and improve safety.
Through the above measures, the ultrasonic sensor can be effectively protected from water erosion, its service life can be extended, and its stable operation in various harsh environments can be ensured.
