40/50X Single Axis Diameter measuring instrument

Overview

As cost-effective industrial online diameter measuring instrument, the 40X/50X laser diameter gauge is customized for medium-large cylindrical blanks. 40X accuracy: ±1μm±0.008%×Z; 50X accuracy: ±2μm±0.008%×Z, unified fixed resolution at 0.001mm(0.000039") and 1400Hz high-speed non-destructive scanning. Approved by CE, SGS, ISO, TUV certifications. Equipped with standard mounting bracket, it can be fitted onto existing equipment without massive production line renovation. Via RS485 communication linking extruder PLC, it realizes automatic closed-loop adjustment, effectively replacing traditional manual caliper sampling and supporting both inline production monitoring and offline laboratory testing.

Key Features

Closed-loop Extruder Linkage Control(Core Advantage)

As professional medium-sized pipe online diameter tester, it comes with standard RS485 Modbus RTU to connect PLC of extruders and haul-off machines. Once measured dimension exceeds preset tolerance, the unit outputs signals to automatically adjust production speed for stable finished size and fewer rejects; Modbus TCP / Profinet are optional for intelligent automated lines.

Two Optional Measuring Ranges for Medium Workpieces

40X:1mm(0.039")~40mm(1.575")；50X:1mm(0.039")~50mm(1.969"). Two specs cover mainstream OD of medium cables, industrial pipes and solid metal rods, forming a complete product lineup together with small-range gauges.

Graded Micron-level Stable Precision

The industrial non-contact laser micrometer features tiered precision: ±1μm±0.008%×Z for 40X and ±2μm±0.008%×Z for 50X with fixed 0.001mm(0.000039") resolution. Imported core optical parts guarantee steady readings without data drift under dusty and fluctuating-temperature workshop environment during long-time nonstop operation.

Non-contact Testing to Protect Workpiece Surface

Working on laser non-contact principle, the cable & solid rod outer diameter detector never touches measured goods, avoiding scratch, indentation and deformation on thick rubber tubes, hard plastic pipes and polished metal bars, lowering reject loss caused by contact measurement.

Wide Temp Adaptability & Low Power Consumption

The extrusion closed-loop outer diameter controller runs reliably from -10℃ to 40℃ continuously, with total power ≤12W to cut long-term operational cost for round-the-clock production and long-hour lab testing.

FAQ

Q1: What’s the main difference between 40X and 50X?

A1: The max measurable OD of 40X is 40mm(1.575") with accuracy ±1μm±0.008%×Z; 50X reaches 50mm(1.969") at ±2μm±0.008%×Z, both single-axis for outer diameter only.

Q2: Can this device connect with haul-off machines and wire drawing machines besides extruders?

A2: Yes, its communication protocol is compatible with control systems of haul-off and wire drawing equipment to achieve full-line linkage adjustment.

Q3: Can users switch between inline fixed mode and offline lab mode freely?

A3: Yes, remove the bracket for desktop lab use or install it for fixed production-line mounting.

Q4: Can optional Modbus TCP/Profinet upload data to factory MES?

A4: Available optional ports support real-time data transmission to upper computer and MES for quality record and traceability.

Q5: Will readings drift under high-temperature fluctuating production workshops?

A5: Premium imported optical parts and industrial sealing guarantee stable measurement within -10℃~40℃ without obvious data drift under normal dusty factory conditions.
