LPJB series edge angle measuring instrument products, including the series-and LPJB200 type, etc. LPJB100 angle measuring instrument side, mainly for rolling edge angle and unequal angle line measurement. Products built two groups photoelectric probe, and has a flip angle compensation feature, which allows the angle of the two sides and the long side length size difference for online testing. Its main functions are: 1, real-time measurements accurately reflect changes in the size of rolling; 2, all-digital high-frequency measurement systems, vertical blind measuring less than 50 mm; 3, enabling the measurement accuracy of the calibration device itself and self-calibration; 4 , the thermal expansion coefficient is set to achieve the temperature correction of measurement results; 5, the angle steel of common defects such as: "equilateral", "wrong roll" and detection; 6, the data "tolerance" and temperature "overtemperature "When the main control room panel and on-site two-way real-time alarm LED; 7, the system includes a number of measurement results, and a sectional curve shows the measurement results with statistical analysis; 8, with a profile data storage (data storage longer than 6 month), historical data query can be accurate to the second; 9, long maintenance intervals, lens maintenance cycle of up to 30 days. Applicable industries: Rolling technical parameters: 1, range: 4-20 # angle (custom) 2, the static measurement accuracy: ± 0.04 mm 3, the dynamic measurement accuracy: ± 0.06 mm 4, measurement frequency: 500 Hz 5, Repeatability: ± 0.02 mm 6, temperature range: -20 ~ +40 ℃
