Core Features
1. Wide measuring range of 0.1–70mm covering medium & heavy cylindrical products
Compared with QP-10A for tiny transparent parts and QP-40A for small & medium workpieces, this 0.1–70mm large-size single-axis extrusion OD monitor with built-in PID boasts an extended detection range. It stably measures large municipal plastic water supply & drainage pipes, thick power cables, heavy industrial rubber hoses and medium solid aluminum/carbon steel round bars. It covers specifications not supported by smaller single-axis models, ideal for manufacturers that only need outer diameter supervision without roundness testing.
2. Integrated PID closed-loop control to stabilize production OD automatically
This large single-beam laser measuring device for thick pipes & heavy cables embeds complete PID operation programs. It compares real-time measured OD with standard process dimensions and outputs speed adjustment signals to dynamically modify extrusion and traction parameters. Frequent manual calibration is greatly reduced, effectively cutting dimension fluctuation and waste during mass production. No extra external controllers need to be purchased, lowering intelligent transformation costs for medium & large profile production lines.
3. Expandable human-machine interaction with rotatable panel & remote display
As a practical wide-span single-axis OD control instrument for heavy extrusion lines, the control panel supports 360° rotation to adapt all kinds of equipment installation angles. Optional long-distance external display screens can be expanded, allowing operators to check dimension data far away from high-temperature extruder hosts and solving viewing difficulties of large fixed production equipment.
4. 1000Hz high-speed stable scanning for complex industrial wide-temperature environments
Scanning at 1000 cycles per second, the 0.1–70mm large-size single-axis extrusion OD monitor with built-in PID accurately captures tiny dimension changes of fast-running thick pipes and thick cables without data delay or jumping. The fully sealed dustproof industrial structure with long-life semiconductor laser enables stable continuous operation in heavy pipe & cable workshops with drastic temperature differences and heavy dust, supporting non-stop 24-hour mass production.
5. Standard Modbus RTU communication for digital transformation of smart factories
Built-in RS485 Modbus RTU interface allows this large single-beam laser measuring device for thick pipes & heavy cables to automatically synchronize real-time OD, tolerance deviation and PID adjustment parameters to upper computers, PLC and MES systems. All inspection data is auto-archived to meet export product quality inspection and refined factory traceability standards. Total power consumption is below 15W for energy-saving long-hour batch production.

FAQ
Q1: How to select among QP-70A, QP-40A and QP-10A single-axis laser diameter gauges?
A1: QP-10A covers 0.1–10mm with optical path optimized exclusively for tiny transparent medical micro tubes, without PID automatic regulation function. QP-40A ranges from 0.1–40mm for small & medium plastic pipes and general cables, with built-in PID. This 0.1–70mm large-size single-axis extrusion OD monitor with built-in PID features a measuring range of 0.1–70mm, specially designed for medium & heavy pipes, thick power cables and medium metal round bars. Prioritize QP-70A if you produce medium & large cylindrical workpieces and need automatic closed-loop OD control without ovality inspection.
Q2: Does QP-70A need an external controller to realize automatic PID dimension adjustment?
A2: No extra external control accessories are required. The full set of large single-beam laser measuring device for thick pipes & heavy cables integrates complete PID closed-loop operation system inside the main unit. One-click activation of automatic dimension regulation is supported, which can directly link extruders and haul-off equipment for synchronous speed adjustment.
Q3: Can QP-70A connect to factory PLC and MES systems to store full-process inspection data?
A3: Fully supported. The device is equipped with standard RS485 Modbus RTU communication. The wide-span single-axis OD control instrument for heavy extrusion lines synchronously uploads real-time OD, tolerance deviation and PID adjustment parameters to factory upper management systems for long-term automatic data archiving, meeting full-process quality traceability control standards.
Q4: Can QP-70A be disassembled for desktop offline finished product inspection?
A4: Two working modes can be switched freely. Matched with original heavy-duty fixing brackets, the 0.1–70mm large-size single-axis extrusion OD monitor with built-in PID can be flexibly mounted on production lines for online monitoring or placed on laboratory workbenches for batch offline finished product inspection.
