TG-5700 High-Precision Ultrasonic Thickness Gauge
The TG-5700 is a new generation handheld high-precision digital ultrasonic thickness gauge featuring A/B scanning capabilities. Utilizing the pulse reflection principle of ultrasonic thickness measurement, it delivers exceptional accuracy with measurement resolution of 0.001mm and range as thin as 0.15mm (steel).
Product Overview
This advanced instrument accurately measures plates and processed components while monitoring corrosion-induced thinning in pipes and pressure vessels during service. Ideal for petroleum, chemical, metallurgy, shipbuilding, aerospace, and energy industries. Complies with Calibration Specification for ultrasonic thickness gauge (JJF 1126-2004).
Main Function Characteristics
- Multiple display modes: A-scan, B-scan, and numerical display
- Wide measurement range with unique "multiple echo" technology for ultra-thin parts (minimum 0.15mm steel)
- High precision measurement with resolution up to 0.001mm and repetition resolution of ±0.002mm
- Penetrating coating and echo-to-echo measurement for materials with surface paint and coatings
- Multiple measurement modes: MB-E, E-E, ME-E for conventional workpieces; THIN mode for thin parts
- Numerical modes: conventional thickness, difference/reduction rate, and maximum value modes
- Dual gain modes: automatic and manual gain control
- Energy-saving function with manual/automatic shutdown settings
- Supports various probes including double crystal and single crystal, up to 20MHz high-frequency
- Mass storage capacity: 100,000 thickness values, 500 A-scan waveforms, 500 B-scan waveforms
- 3.5-inch color TFT-LCD display with 320x240 QVGA resolution
- Multiple calibration methods: one-point, multi-point, and manual calibration
- Metric/imperial unit conversion and English language support
Applicable Materials
Suitable for measuring thickness of metals (steel, cast iron, aluminum, copper), plastics, ceramics, glass, resin, fiberglass, and other ultrasonic conductors.
Basic Principles
Ultrasonic thickness measurement operates similarly to light wave measurement. The ultrasonic pulse emitted by the probe propagates through the material and reflects from interfaces. Material thickness is determined by precisely measuring ultrasonic propagation time through the material.
