Core Features
1. Wide measuring range 0.1–40mm for all kinds of medium extruded workpieces
Compared with QP-10A with only 0.1–10mm measuring range, this 0.1–40mm mid-range single-axis OD monitor with built-in PID has a much wider detection scope, covering medium plastic hoses, general cables, solid metal round bars, rubbers and thick plastic monofilaments. As a universal wide-range single-beam outer diameter measuring instrument, it supports both transparent and opaque materials with wider application coverage, ideal for medium and small pipe & cable extrusion factories.
2. Integrated built-in PID closed-loop to stabilize production dimension automatically
Different from ordinary single-axis diameter gauges without regulation functions, this industrial single-axis laser OD controller for extrusion lines embeds native PID closed-loop adjustment program with one-click auto diameter control mode. The equipment automatically outputs speed regulation signals according to real-time OD deviation, dynamically adjusting parameters of extruder and haul-off equipment. It reduces frequent manual adjustments and rejects caused by dimension fluctuation during mass production, eliminating extra cost of purchasing external control modules for production line renovation.
3. Optimized Fθ optical lens with anti-shift design for stable readings
Most simple single-axis gauges generate data jump when workpieces shift slightly. The 0.1–40mm mid-range single-axis OD monitor with built-in PID is fitted with professional Fθ correction optical lens to correct optical path distortion. Even if the workpiece moves slightly left and right in the measuring channel, OD readings remain steady, greatly lowering data error from placement offset and extrusion vibration, and improving overall dimension control precision of production lines.
4. 360° rotatable control panel & remote display for convenient workshop operation
The whole machine control panel supports multi-angle rotation, operators no longer need to adapt to fixed equipment installation angle. A long-distance external display is optional to check dimension data in real time far away from high-temperature extruder host. As a practical wide-range single-beam outer diameter measuring instrument, its human-machine interface design adapts to various narrow and high-temperature production line installation conditions and lowers on-site operation difficulty.
5. Durable industrial hardware with wide temperature & dustproof design for complex mass production workshops
Adopting long-life semiconductor laser source and brushless scanning motor, the whole machine features sealed dustproof structure. This industrial single-axis laser OD controller for extrusion lines can operate continuously in pipe & cable workshops with temperature difference of -10℃~45℃ and heavy dust. Standard Modbus RTU communication enables data upload to PLC and MES systems for traceable full-process dimension records. Low overall power consumption ensures energy-saving operation during long-hour mass production.

4. Thick plastic monofilament & modified plastic extrusion profile industry
Application: Mount this unit on plastic monofilament and small modified plastic extrusion lines for online diameter control. The 0.1–40mm mid-range single-axis OD monitor with built-in PID automatically restrains dimension fluctuation to guarantee consistent outer diameter of monofilaments and small plastic strips.
Applicable Materials: Thick plastic fiber monofilaments, nylon extruded small round strips, modified plastic small cylindrical profiles
FAQ
Q1: How to select between QP-40A and QP-10A single axis laser diameter gauge?
A1: QP-10A covers 0.1–10mm and is only designed for tiny transparent medical micro tubes and ultra-fine monofilaments. This 0.1–40mm mid-range single-axis OD monitor with built-in PID ranges from 0.1mm to 40mm and comes with built-in PID closed-loop regulation for medium pipes, cables and metal round bars. If you need automatic dimension control and test medium-size workpieces, prioritize the industrial single-axis laser OD controller for extrusion lines QP-40A. Choose QP-10A only if you merely test tiny transparent thin materials without automatic regulation demands.
Q2: Will measuring data jump if the workpiece shakes slightly in the measuring channel?
A2: No. The machine is equipped with dedicated Fθ correction optical lens. This 0.1–40mm mid-range single-axis OD monitor with built-in PID offsets optical path error brought by minor workpiece displacement and maintains stable readings even with slight vibration during extrusion.
Q3: Can QP-40A connect to factory PLC and MES systems for data storage?
A3: Yes. It is equipped with standard RS485 Modbus RTU communication interface. The industrial single-axis laser OD controller for extrusion lines uploads real-time outer diameter, deviation and PID adjustment parameters for automatic data archiving to meet production traceability management standards.
Q4: Can the equipment be detached for desktop offline inspection?
A4: Yes. Matched with original fixed bracket, the wide-range single-beam outer diameter measuring instrument can flexibly switch between online installation on production lines and desktop sampling inspection in laboratories.
