Wall thickness measuring instrument BenchMike Pro

dimensionaldiametereccentricity

Overview
BenchMike Pro delivers fast, precise and repeatable diameter and ovality measurements of cut pipe, tube, hose, wire, cable, fiber optic and other cylindrical products. Using non-contact laser gauging and a compact benchtop design, it is suitable for extrusion lines and quality control laboratories to provide immediate dimensional feedback to operators and technicians.

Features & Benefits

• Over 15,000 gauges installed worldwide at leading manufacturers.
• High precision: ±0.76 to ±1.5 µm accuracy depending on model, repeatability down to ±0.25 µm.
• Non-contact laser measurement avoids distortion or surface damage and removes operator-influenced errors.
• Intuitive touch-screen GUI, product recipe library and flexible I/O for integration.
• Ethernet connectivity and communication capabilities for Industry 4.0 integration.

Wire & Cable Off-Line OD Measurement
The rotary chuck fixture enables motorized rotation of shafts or wires to detect diameter variation around the circumference. BenchMike Pro provides high-precision OD measurements within sub-micron specifications for wire and cable when used with appropriate fixtures.

Ultra-Fine Wire Off-Line Diameter Measurement
The Ultra Fine Wire V-Block fixture holds tensioned wires in the 0.025 to 0.254 mm range and is used with the Small Spot Size option for accurate diameter measurement of ultra-fine wire.

Medical Tubing Off-Line ID/OD/Wall Measurement
The ID/OD/Wall fixture measures internal diameter, external diameter and wall thickness on thin-wall, small-diameter medical tubing. The fixture applies controlled force and the system calculates all dimensions and wall measurements.

Pipe & Tube Off-Line OD and ID/OD/Wall Measurement
Using V-block fixtures (and ID/OD/Wall where applicable), BenchMike Pro delivers fast OD, ID and wall thickness measurements on pipe and tube samples. The system can rotate a sample to predefined positions for multi-point measurement and can calculate concentricity and ovality. The GUI displays rotational cross-section views and deviation graphs versus rotation angle.
