Overview
The TrueWall is an ultrasonic gauge for continuous measurement of wall thickness and concentricity on round products. It is available in multiple models to cover a broad OD range and supports multi-layer and thin-wall discrimination for tubing, hose, pipe, insulated wire and cable manufacturers.

Features & Benefits

• Automatic measurement — measures wall thickness without operator input, enabling consistent inline inspection.
• Snap setup & calibration — fully automatic setup and calibration for fast changeovers.
• Multi-layer & thin-wall capability — discriminates up to 4 layers and measures very thin walls using a thin-wall algorithm.
• Compact installation — gauge heads mount in trough or via sealed diaphragm for external mounting, minimizing footprint.
• Industry 4.0 connectivity — embedded webserver, Ethernet, encoder and I/O support for production integration.

Models & Key Ranges
Measurements: TrueWall 1012 | TrueWall 1025 | TrueWall 1040 | TrueWall 1063
OD Range: 0.25–12 mm | 2.5–25 mm | 4–40 mm | 7.5–63 mm
Minimum Wall Thickness (examples): 10 MHz: 0.254 mm; 20 MHz: 0.127 mm; Thin-wall option (20 MHz): 0.025 mm (applies where available).
Transducers: model-dependent (4, 6, 8); Frequencies: 1 MHz, 2.25 MHz, 5 MHz, 10 MHz, 20 MHz depending on model.

High-Speed Tolerance Checking
The system can perform up to approximately 10,000 wall measurements per second (dependent on thickness and configuration) and evaluates each transducer scan against configured tolerances to detect short-term variations on each layer.

Multi-Point Wall & Concentricity
Four to eight adjustable transducers surround the product to evaluate critical locations and provide fast, accurate wall-thickness and concentricity measurements across the circumference.

Multi-Layer and Thin-Wall Measurement
Advanced sensitivity and algorithms enable discrimination of up to 4 layers and accurate measurement of very thin walls across selectable transducer frequencies.

Embedded Webserver
Local web interface for setup, tolerance configuration, recipe management and diagnostics. Key capabilities include:

• Display of centering, wall thickness, eccentricity and diameter.
• Integration of external laser OD measurements.
• Support for line speed (encoder/LaserSpeed) and discrete I/O.
• Recipe and settings configuration and internal diagnostics; multilingual UI available.

OD Ultrasonic Measurement Option
An OD ultrasonic option uses optimized transducer echoes to provide high-precision outer diameter information as a cost-effective alternative to laser OD scanning in many applications.

External (Self-Flooding) Measurement
For measurements outside a cooling trough, TrueWall can be configured with a sealed, water-tight diaphragm assembly to immerse the gauge for external, submerged measurements.
