Rod materials generally refer to a type of material product with a cross-sectional shape that is a simple shape such as circular, square, hexagonal, or octagonal; it has a length that is relatively large compared to its cross-sectional dimensions, and it is usually supplied in the form of straight bars. Since the cross-section of a rod is not circular, its diameter cannot be determined by a single diameter value. To obtain data on rod-shaped materials, multiple measurements need to be taken within the same cross-section in order to determine its diameter, and the average diameter is calculated from these measurements. The Lanpeng Measurement and Control optoelectronic series of rod diameter meters utilize multiple sets of optoelectronic measurements, relying on the principle of optoelectronic conversion to determine the diameter of rods. The diameter measuring instrument can be equipped with 8 sets of photoelectric probes, which allow for the simultaneous measurement of 8 diameter values at each measurement section; based on these measured values, the diameter, average diameter, and ellipticity of the measurement surface can be determined. 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 ； The on-site LED display and the industrial computer are connected using TCP/IP standard industrial interfaces and optical fiber transmission ； 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 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 excellent 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. Not only that, but this device can also perform online geometric dimension measurement on ribbed steel bars (reinforcing bars). It is possible to measure characteristic dimensions of deformed steel bars, such as the inner diameter, longitudinal ribs, and transverse ribs.
