The protection level is determined by first considering the protection against solid foreign objects. For example, the first number in the IP code indicates the degree of protection against the ingress of solid foreign objects. The larger the number, the stronger the protection. 0 means no protection, while 6 means complete protection against dust ingress. This is achieved through the sealing design of the structural parts, gap control, and the use of appropriate filter materials. The material, manufacturing process, and connection method of the structural parts will affect the protection against solid foreign objects. If the structural parts are made of high-strength, well-sealed materials, and the processing accuracy is strictly controlled during the manufacturing process to reduce gaps, the protection level against solid foreign objects can be improved.
Secondly, the protection level also depends on the protection against liquids. The second number in the IP code indicates the degree of protection against water. Different levels from no protection to continuous immersion protection involve the waterproof design of the structural parts. This may include the use of waterproof sealants, rubber gaskets, special waterproof coatings, etc. For sensor structural parts that may be exposed to humid environments or underwater, strict waterproof testing is required to ensure that they can maintain good sealing under specific water pressure and time conditions to prevent moisture from entering the interior and damaging the sensor elements.
In addition, the use environment of the sensor is also an important factor in determining the protection level. If the sensor will be used in a harsh industrial environment, it may be affected by dust, chemicals, vibration and other factors, so a higher protection level is required. In a relatively mild indoor environment, the protection level requirement may be relatively low.
In the process of determining the protection level, the function and performance requirements of the sensor also need to be considered. Some high-precision sensors may be very sensitive to environmental changes, so a higher protection level is required to ensure its accuracy and stability. At the same time, the increase in protection level may also bring about an increase in cost and complexity in structural design, so it is necessary to make a reasonable choice on the premise of meeting the use requirements.
The protection level of Sensor Structural Parts is determined by comprehensively considering multiple factors such as the protection ability against solid foreign matter and liquids, the use environment, and the functional requirements of the sensor.
