The working principle of a cleanroom specific telephone is similar to that of a traditional telephone. Its basic communication process includes key input of numbers, dialing, answering calls, making calls, and hanging up. The difference is that the working process of the cleanroom dedicated telephone needs to consider the requirements of the cleanroom and achieve the following:
1. Grounding protection
Metal flooring is generally used in cleanrooms to ensure grounding, directing static electricity and noise underground to prevent interference with equipment. For cleanroom specific telephones, grounding protection is also very important. It is necessary to ensure a good electrical connection between the telephone and the ground through power grounding, line shielding, and other methods.
2. Dust prevention measures
The purpose of a cleanroom specific telephone determines its need for effective protection against dust and bacteria in the surrounding air. Firstly, the casing of the telephone needs to have good sealing to prevent dust from entering the interior; Secondly, internal components need to be packaged and dust-proof to prevent contamination.
3. Corrosion resistance characteristics
Cleanroom environments generally use cleaning agents with special chemical properties for cleaning, which may have a corrosive effect on materials. Therefore, the shell, clip and other components of the cleanroom specific telephone need to have good corrosion resistance.
4. Good call quality
Cleanroom specific telephones need to ensure good communication quality, which can be achieved through the following measures:
(1) Using noise reduction technology to filter out noise from the surrounding environment;
(2) Adopting a well-designed language to make the other person's voice clear and audible;
(3) When designing acoustic protective covers, fully consider the reflection and absorption characteristics of sound to achieve good sound quality.
