Wall Thickness Measurement with the ECHOMETER 1077: Precision Ultrasound Testing

Overview

Wall thickness measurement using ultrasound is essential in scenarios where access to the measurement point is restricted to one side, making traditional caliper gauges impractical. The ECHOMETER 1077 is designed to provide highly accurate measurements with a precision of up to 0.01 mm, catering to demanding applications such as precision tube manufacturing and automotive body construction.

Key Features

• Accurate Measurement: Utilizing multiple echo measurements, the ECHOMETER 1077 employs mono-element straight probes with and without delay lines, enabling precise wall thickness evaluation.
• High-Resolution A-scan Display: The device features a high-resolution A-scan display, allowing users to visualize the ultrasound signal. This is particularly beneficial for materials with sound issues, as it helps in adjusting measurement parameters, including measurement range and signal evaluation.
• Automatic Gain Control: The ECHOMETER 1077 includes manual and automatic gain control options, along with selectable automatic depth compensation. This feature balances the signal attenuation of up to four initial echoes, ensuring they are amplified to the same screen height, which is crucial for materials exhibiting high signal attenuation.
• Versatile Measurement Modes: The device supports various operating modes, such as transmitter pulse to backwall echo and backwall echo to backwall echo, providing flexibility for different testing scenarios.
• Comprehensive Monitoring and Configuration: The ECHOMETER 1077 allows for limit value monitoring and offers multiple evaluation options, including polarity, TP-BE, and BE-BE. Users can also store up to 20 different configurations for quick access to standard applications.

Technical Specifications

• Measuring Range: 0.25 to 400 mm (dependent on probe type, material properties, and operating mode).
• Resolution Options: 0.1 mm, 0.01 mm, and 0.001 mm.
• Sound Velocity Range: 100 – 19,999 m/s.
• Display: High-resolution color display with 320 x 240 pixels.
• Measurement Units: Options include mm, inch, m/s, inch/µs, and µs.
• Display Modes: Direct display, average, minimum, difference, and relative.
• Memory and Analysis: Capable of storing various configurations and performing statistical analysis.

Applications

The ECHOMETER 1077 is ideal for:

• Precision Tube Manufacturing: Ensuring consistent wall thickness for high-quality tubing.
• Automotive Body Construction: Measuring the integrity of car bodies and components.
• Pipes Body Inspection and asset integrity
• Material Inspection: Evaluating the thickness of materials in manufacturing and construction settings where access is limited.
