Many customers confuse our measurement grating and safety grating during inquiries, but in fact, they are quite different. The safety grating is crucial for customer safety protection, while the measurement grating is used for detection and measurement. The actual distinction between measurement gratings and safety gratings is as follows: Measurement gratings, also known as measurement screens, are derivative products of safety gratings. Their function is to better detect the presence or measure specific areas. This includes applications such as volume measurement, relative height detection, and vehicle separation detection, among others. The grating used for detection is called a detection grating, while the one used for measurement is called a measurement grating. The measurement is based on the grade of light blocking multiplied by the linear light axis interval. For more information on types of measurement gratings and their applications, refer to the article. Measurement gratings and detection gratings are most concerned with measurement accuracy and response speed, as the basic working principle of gratings is point-by-point scanning, which introduces a delay when measuring moving objects. Therefore, those with shorter response times have smaller measurement errors. Another factor to consider is measurement accuracy, which is the interval between the linear light axes. Additionally, product quality reliability must be considered, including resistance to interference signals and sunlight exposure. Although they may look similar on the surface, their basic principles and functions are entirely different.
