LPBJ Bar Gauge Series This series includes LPBJ100 type and LPBJ300 type and other types of bar diameter measurement, the measuring range can be customized according to user requirements. Products built multiple sets of fixed double barrel photoelectric probe, each measuring cross-section at least four directions can be measured diameter, the product can achieve the following functions: 1, real-time measurements accurately reflect changes in rolling; (2), all Digital high-frequency measuring system is less than 50 mm measured longitudinally blind; 3, the device itself can be realized, and measurement accuracy of the calibration of the self-calibration; 4, the thermal expansion coefficient is set to the measurement results can be achieved temperature correction; 5, common defects on the bar Such as: "ears", "wrong roll" and other detection; 6 Data "ultra-poor" or temperature "over temperature" control room and on-site two-way real-time alarm LED screen; 7, the system has a digital measurement results, cross sections and curve shows the measurement results with statistical analysis; 8, with a shot from the side data storage function (data stored longer than six months), historical data query can be accurate to the second; 9, using stand-over-steel guide and guard, to avoid heap steel, rolled steel, wire run accident damage to the measuring vehicle; 10, long maintenance intervals, lens maintenance intervals up to 30 days. Applicable industries: metallurgy, steel rolling, cables and so on. Technical parameters: 1, measuring range: φ10 ~ φ300mm (custom) 2, the static measurement accuracy: ± 0.04 mm 3, the dynamic measurement accuracy: ± 0.04 mm 4, measurement frequency: 500 Hz 5, Repeatability: ± 0.013 mm 6, use Temperature range: -20 ~ + 40 ℃
