The 50XY High-Speed Dual Axis Laser Diameter Gauge is a dedicated dual-axis non-contact laser measuring device for large-caliber workpieces. This medium & large pipe/rod dual-axis laser micrometer adopts a 90° vertically orthogonal dual laser optical path to simultaneously collect X and Y bidirectional outer diameter values. The built-in operation program automatically calculates workpiece ovality, solving the defect of single-axis equipment that only measures unidirectional diameter and cannot identify section eccentricity of large pipes and bars.
It delivers measuring accuracy of ±1.5μm±0.008%×Z and fixed resolution of 0.001mm(0.000039"), supporting 1400Hz high-speed lossless dynamic sampling. It holds complete international certifications including CE, SGS, ISO and TUV, and adapts to heavy-duty extrusion workshops with high temperature and heavy dust from -10℃ to 40℃.

Key Features
1. Exclusive measuring range of 1~50mm for medium and large-sized heavy workpieces (Core differentiated advantage)
Different from 3XY (0.05–3mm ultra-micro workpieces) and 15XY (0.05–17mm medium and small general parts), this large-size dual-axis OD & ovality detector has a lower measuring limit of 1mm and upper limit of 50mm. It accurately covers large cross-section products including high-voltage power cables, thick-walled water supply and drainage pipes, solid aluminum alloy round bars and large extruded profiles, filling the gap of large-size detection in the full series of diameter measuring equipment. This medium & large pipe/rod dual-axis laser micrometer is perfectly suitable for cable factories, heavy pipe extrusion workshops and metal bar rolling production lines, and the large cable online ovality monitoring equipment function ensures full online roundness inspection for power cable extrusion lines.
2. Graded micron-level stable accuracy for wide-temperature heavy workshop conditions
This wide-range extrusion closed-loop controller equips an optical module optimized for optical detection of large workpieces, with stable measuring accuracy of ±1.5μm±0.008%×Z and fixed resolution of 0.001mm(0.000039"). The whole machine adopts industrial-grade sealed protection structure, which can run 24 hours uninterruptedly in heavy extrusion workshops with temperature fluctuations and heavy dust from -10℃ to 40℃, without obvious drift of outer diameter and ovality detection data. Whether you use this large-size dual-axis OD & ovality detector for thick pipe production or the large cable online ovality monitoring equipment for high-voltage cable manufacturing, stable measurement data can be guaranteed all day long.
3. 90° orthogonal dual optical paths for simultaneous OD & ovality detection, non-contact protection for large raw materials
Two vertically arranged laser transmitters collect outer diameter in two perpendicular directions at the same time and calculate ovality in real time, accurately capturing section eccentricity deformation of large profiles caused by die wear and uneven traction force, avoiding hidden defective products missed by single-point single-axis measurement.
The whole testing process of the medium & large pipe/rod dual-axis laser micrometer adopts laser non-contact scanning, so thick rubber pipes, polished metal round bars and hard engineering plastic pipes will not have indentations or scratches, greatly reducing the scrap cost of large raw materials. As a core part of the wide-range extrusion closed-loop controller, the non-contact detection design lowers production loss for heavy industry manufacturers.
4. Multi-protocol industrial communication & complete optional accessories for free desktop/inline switching
Standard RS485 Modbus RTU basic communication is provided, with optional Modbus TCP and Profinet industrial Ethernet ports to connect factory PLC and MES systems, fully storing full-process dimension data for quality traceability. Original factory complete installation accessories are matched, which can be quickly installed on old large-caliber extrusion lines without large-scale disassembly and reconstruction.
Total power consumption ≤12W, maintaining low-energy operation during long-time mass production and laboratory batch sampling inspection. Factories deploying this large-size dual-axis OD & ovality detector or large cable online ovality monitoring equipment will enjoy convenient equipment transformation and low daily operation cost brought by the wide-range extrusion closed-loop controller.
