Contact Thickness GaugeAuthor : hani Time : 2019/03/12
Contact thickness gauge is a kind of high precision metal plate thickness online measurement equipment, which can rapidly and accurately gauge the metal strip thickness of strip or actual deviation in the process of production. The thickness gauge is not affected by strip material and chemical composition. It is easy to use and reliable. It is “0” radiation, green environmental protection product. Compared with ray measurement, it’s accuracy is higher, harmless to human health. The thickness gauge eliminates the cumbersome procedures of environmental approval and filing.
Thickness gauge precision is generally divided into static precision and dynamic precision.The contact thickness gauge directly measures the thickness of the strip with the upper and lower probes, regardless of the chemical composition of the strip and the uniformity of the material.
Contact thickness gauge is to use two probes directly measuring the thickness of the strip, and has nothing to do with the chemical composition of the strip and the uniformity of the material. The system does not need to be calibrated frequently, so the static accuracy is high.
The strip is running at high speed during the rolling process. In order to stop the slight fluctuation of the strip, a clamping roller is designed on both sides of the thickness gauge, and a high-precision differential transformer displacement sensor is installed in the upper and lower probes of the thickness gauge, with dynamic measurement accuracy of ± 1um.
