40+ Measurements/Minute: The Fastest Way to Ensure Coating Quality

Advanced Ultrasonic Coating Thickness Gauge for Multi-Layer Analysis

The ultrasonic coating thickness gauge represents a significant leap forward in non-destructive testing (NDT) technology. As a premier Measuring Testing Instrument, this device is engineered to perform precise thickness measurements of various coatings, including paint and plastic, applied on a diverse range of substrates such as plastics, metals, wood, glass, and ceramics. A standout feature of this advanced gauge is its ability to measure the thickness of up to 8 distinct coating layers simultaneously without causing any damage to the material. This capability is invaluable for quality control in complex manufacturing processes where multiple layers of protection or finish are applied.

Supplied by industry leaders like Mikrosize, this thickness gauge incorporates innovative ultrasonic technology that enables it to tackle challenging materials that are often difficult to measure with other methods. It is specifically designed to deliver accurate and reliable measurements on GRP (glass-reinforced plastic or fiberglass) and CRP (carbon-reinforced plastic) workpieces, as well as on substrates like low-temperature steel. This makes it an indispensable tool across industries such as aerospace, automotive, marine, and industrial manufacturing, where composite materials are increasingly used.

Measurement Principle: Intelligent Ultrasonic Pulse-Echo

The core operating principle of this gauge is based on sophisticated ultrasonic pulse-echo technology. The system is equipped with an intelligent ultrasonic sensor for measuring coating thickness, which is typically connected to a powerful industrial tablet or PC that acts as the evaluation unit. In this setup, the sensor functions as both a transmitter and a receiver. It transmits high-frequency ultrasonic pulses into the coating system through a coupling medium, such as a gel or fluid. These pulses travel through the layers, and signals are reflected at each interface between different materials. The sensor then captures these returning echoes. By precisely evaluating the time it takes for the ultrasonic pulses to penetrate and return from each layer, the integrated software can accurately calculate and convert these time-of-flight measurements into corresponding layer thicknesses.

Comprehensive Evaluation and Data Management Software

The power of this Measuring Testing Instrument is fully realized through its convenient and robust testing and data management software. The software provides a clear, visual interface that not only displays real-time A-scans—the fundamental waveform of the ultrasonic echo—but also allows for deep analysis of these signals on a high-resolution flat panel display. Users have full control and can easily edit and set all available measurement parameters to suit specific application needs. Furthermore, the software allows for the storage of individual A-scan files, enabling subsequent adjustments such as clipping or masking specific areas of interest for more detailed analysis.

A key feature provided by suppliers like Mikrosize is the comprehensive data management function. All measurement values can be systematically organized, exported in versatile text and Excel formats for further statistical analysis, and used to generate complete, professional measurement reports in PDF format. To support thorough documentation, the software allows for the integration of descriptive text and photos alongside measurement data, creating a complete and traceable record for audits and quality assurance protocols.

Key Features and Operational Advantages

This ultrasonic coating thickness gauge is packed with features that ensure high performance and user efficiency. Central to its operation is the Sensor Integrated Digital 32-bit Signal Processing (SIDSP®) technology. This proprietary innovation allows for the rapid evaluation of measurement signals with exceptional accuracy and outstanding repeatability, ensuring consistent results even in high-throughput environments. The system's speed is remarkable, capable of performing more than 40 measurements per minute—users can simply start the measurement, wait for about one second, and the reading is complete.

Its practical design also addresses common measurement challenges. With a minimal measuring area requirement of only 5 millimeters in diameter, the gauge is perfectly suited for inspecting small components and highly curved parts that are typically difficult to assess with other gauges. This combination of speed, precision, and versatility solidifies its status as an essential Measuring Testing Instrument for any operation dedicated to maintaining the highest standards of coating quality and integrity.
