The main components of the wire diameter measuring instrument are installed on the rolling production line to measure the outer diameter. The important eight-axis probe is located there; it is crucial for on-line measurement. Moreover, since it is used in harsh production environments, a cooling and dust-proof system must be installed to ensure its proper operation. Wire diameter tester: The wire diameter tester is used for online measurement of the diameter of wires; it is a key component of photoelectric online diameter testers. The entire inspection head consists of 8 pairs of measuring heads, which are arranged at equal intervals on the same plane as the cross-section of the wire. This ensures that the measurement data obtained at any given moment come from the same diameter cross-section of the wire, thereby improving the accuracy of the measurements and facilitating subsequent data processing. The data detected by each pair of measuring heads in the inspection head is transmitted to the main control cabinet via the RS—422/485 bus. To ensure that the optical system of the measuring head functions properly when high-temperature wires pass through its field of view, a cooling and dust-proofing method that combines air cooling with water cooling is employed, keeping the optical detection components within the cooling system. To monitor the cooling effect and protect the optical detection components, a temperature sensor is also installed on them to check whether the temperature after cooling exceeds the specified level ； At the same time, a high-pressure blower is installed to blow away debris such as iron oxide scale that can affect measurements. The wire to be inspected passes through the guides, ensuring it moves through the center of the inspection head and remains within the area required for measurement; even if the wire shifts during movement, the diameter of the wire can still be measured with precision. The main body of the on-site diameter measuring instrument can operate in various harsh environments; it provides alarms for deviations from specified limits and excessive temperatures. Its parameter settings are simple, and different specifications can be easily updated, making it an ideal device for measuring outer diameters.
