The definition of ellipticity is the difference between the diameters of the cross-sectional thresholds of the object being measured. To determine the ellipticity of the object under test, it is necessary to measure its cross-sectional diameter multiple times. The Lanpeng multi-functional diameter measuring instrument, when installed after the finish rolling mill, performs on-line geometric dimension testing of the rolled products as they pass by. A TCP/IP standard industrial interface and optical fiber transmission are used between the diameter measuring instrument and the host computer; the detection signals are sent to the industrial computer in the main control room ； A TCP/IP standard industrial interface and optical fiber transmission are used between the on-site LED display screen and the industrial computer ； The LCD display terminal in the control room shows content in synchronization with the on-site LED display. It can reflect the dimensional changes of the rolled products in real time, enabling the personnel on site to adjust the rolling mill or die sets promptly. The probe of the diameter measuring instrument is made of aluminum alloy, offering good heat dissipation properties. Under the operating condition of the high-pressure centrifugal fan continuously supplying air to the diameter measuring instrument, it is possible to keep the photoelectric components inside the probe within their normal operating temperature range. A diameter meter can perform online simultaneous measurements on smooth round steel bars, small rods, and ribbed steel bars (reinforcing bars). The product is equipped with multiple sets of photoelectric probes, which enable the simultaneous measurement of 8 diameter values at each measurement section; based on these measured values, the diameter, average diameter, and ellipticity of that measurement section can be determined. For ribbed steel bars, special dimensions such as the inner diameter, longitudinal ribs, and transverse ribs can be measured simultaneously. Due to its lack of time error, immunity to temperature fluctuations, stable performance, and long service life, this detection method is highly favored in the steel industry.
