Polarized stress meter PSV-203 Scope of application: ï¬ Accurately detect the camera, the lens of the microscope. ï¬ Adjustment and testing of plastic molds during processing. ï¬ Detect glass art and so on. Observe the micro stress of transparent glass and plastic products, and analyze the internal stress direction of the object through the change of the color tone of the photosensitive color to determine whether it is tensile stress or compressive stress. Suitable for stress detection of transparent glass or plastic products on precision instruments. In addition, in the plastics manufacturing industry, it is advantageous to set the processing conditions such as cutting. parameter: Model PSV-203 Size W295 & TImes; D370 & TImes; H450mm Weight 10Kg Measuring method Sample effective length W200 & TImes; D200mm Measuring space height 295mm Light source fluorescent lamp 22W Power supply 220V Net weight 10KG Cyclic polarization detection The entire field of view will appear black. The sample is placed on the observatory, the area where the stress is present is bright white, and the portion without stress will appear black, the same black as when the sample is not placed. When the stress is relatively large, the distribution of stress does not change even if the sample is rotated. Because the detection is not affected by the direction of the principal stress. This is the advantage of the circular polarization method.
