Use of reverse vacuum detector

• purpose

Vacuum insulation board reverse vacuum detector NC-2000It is specifically designed for Designed for quality inspection of vacuum insulation panels. By using high-sensitivity detection sensing elements and highly integrated methods, accurate, fast, and efficient detection can be achieved, reducing the detection time of a vacuum insulation board to60SWithin, truly achieve Rapid detection of vacuum degree of vacuum insulation board,Truly realizing products for users100%Full inspection provides the possibility, and one person can operate multiple detection instruments, with detection efficiency *.

• Principle and Structure

Based on the analysis of the internal air pressure of the vacuum insulation board,VIPThe internal vacuum degree is between1~10PaBetween them, whenVIPPlaced inside a vacuum chamber, when the vacuum level inside the chamber decreases,VIPThe surface film material will expand to a certain extent. According to this principle, after many tests and based on model calculation, the relationship between the lift height of the film material and the vacuum degree, that is, the vacuum degree in the plate, can be obtained.
