The on-site conditions in hot-rolling wire production are extremely harsh, with plenty of dust and moisture, as well as severe electrical interference. Additionally, due to the high temperature of the wires themselves, a rod diameter measuring instrument can be used to detect the outer diameter. The rod diameter meter solves the problem of wire twisting through its circuit design. It is an optical machine device that does not rotate around a wire shaft; it uses an eight-axis detection method to achieve comprehensive inspection as well, and features high reliability and low cost. At the same time, jitter errors are eliminated by employing various synchronization techniques such as pulse synchronization between the light source and the signal acquisition unit, multi-channel acquisition synchronization, and synchronization between signal acquisition and communication transmission. As an optical inspection device, it uses a solid-state imaging device (linear CCD). Compared to laser diameters, it does not require an optical scanning mechanism. The measurement is accurate; the dynamic error for rolled round bars is no more than 0.02 millimeters ； The dynamic error of the spiral coil is no more than 0.05 millimeters. The diameter measuring instrument features a carefully designed and calculated optical path system, resulting in clear image boundaries. Adjusted with a precision of 3 micrometers, the diameter gauge does not require calibration for any dimensions within its measurement range during normal use, providing unprecedented convenience to users; it also offers high precision without the need for careful adjustment. The caliper housing is designed with an IP54 protection rating to prevent dust from entering and splashed water from reaching it, enabling use in harsh environments. Self-circulating cooling system: the main body of the fixed probe is connected to the water jacket. The water jacket is filled with antifreeze coolant, which circulates on its own and dissipates heat through the radiator. It can effectively cool the main housing, ensuring the operating temperature of the probe. A duckbill side-blowing dust prevention system is used for the cleaning and protection of the probe window lenses; high-pressure, clean cold air blows from an angle above the lens surface, effectively preventing dust from contaminating it. The pre-water removal system features a blowing structure in various forms, from multiple directions and across multiple stages, which blows away contaminants such as water, oil, and dust attached to the object being measured. This helps improve measurement accuracy and prevents the sensing head from becoming contaminated. A rod diameter measuring instrument can measure the outer diameter and ellipticity; it provides analysis charts such as fluctuation graphs, defect maps, cross-sectional views, and trend graphs. It allows for remote display, can detect surface defects like bulges, and is capable of storing data over the long term. As an online inspection device, the rod diameter meter is used in various steel rolling production lines; it is capable of withstanding various harsh environments and ensures high-quality production.
