I have a question regarding high-temperature thickness measurement instruments.
Thread Content
I would like to ask the experts: How do you carry out thickness measurement on the pipelines and equipment that operate at temperatures between 100-400 degrees Celsius, and which instruments are the best for this purpose? Thank you.
1. Instrument Introduction: The ETG-100 electromagnetic ultrasonic thickness gauge is a contactless measuring device that does not require a sound coupling agent, and it can be used to determine the thickness of metallic materials. Compared with conventional piezoelectric ultrasonic thickness gauges, it has the following advantages: (1) It enables non-contact measurement without the need for polishing on rough or severely corroded surfaces ； (2) It is not sensitive to coatings, allowing for the measurement of workpieces with coatings ； (3) No acoustic coupling agent is required; it enables the measurement of high-temperature workpieces, as well as high-temperature alarms and temperature compensation ； (4) A specially designed thickness measurement algorithm that provides high precision. 2. Performance parameters: Measurement range: 1.2–400 mm; Maximum resolution: 0.01 mm; Ultrasonic frequency: 4 MHz; Sampling frequency: 100 MHz; Attenuation: 100 dB; Temperature range of the workpiece being inspected: -40–700°C (higher temperatures can be specified upon request); Magnetization method: Permanent magnet (pulse electromagnet option available); Probe construction: Ceramic wear-resistant layer for impact resistance and durability; Probe types: High-temperature probes, room-temperature probes, and B-scan probes are available; LCD brightness: Up to 800 cd/m2, ensuring clear visibility even in daylight
