Ultrasonic thickness gauge

Japan A&D AD-3255Ultrasonic thickness gaugeDetailed introduction:

Japan A&D AD-3255Ultrasonic thickness gaugeIt is a well-designed and comprehensive industrial measurement tool widely used in industries such as manufacturing, petrochemicals, aviation, and metal processing. Its core working principle is based on ultrasonic pulse reflection technology, which can quickly and accurately measure the remaining thickness of materials without damaging the surface of the measured object. It is particularly suitable for detecting key components such as metal pipelines, pressure vessels, or ship steel plates that have become thinner due to corrosion and erosion.

*Measurement performance

The measurement range of AD-3255 is very wide, covering 0.8mm to 300mm (with slight differences in probe type and material sound velocity), which can meet the measurement needs from thin-walled pipes to large castings. Its display resolution can be switched between 0.01mm and 0.1mm, ensuring high precision measurement while also considering the reading efficiency of conventional measurements. The instrument is pre-set with the sound velocity of common materials and supports single point or two-point calibration. Users can adjust it according to the actual measured material to ensure the accuracy of the measurement results.

Flexible probe configuration and coating penetration measurement

In order to adapt to diverse detection scenarios, AD-3255 supports the selection of multiple types of probes. The standard configuration is usually a 7MHz or 5MHz contact probe, which is suitable for conventional thickness measurement and thicker or more attenuated materials, respectively. It is worth mentioning that it supports through coating measurement function (requires the use of a dedicated probe). Through a special echo echo measurement mode, the instrument can ignore surface coatings such as paint and anti-corrosion layers, and directly measure the actual thickness of the substrate material. This saves a lot of polishing and pre-treatment time for detecting equipment with coatings.

Practical scanning mode and operational experience

This device has an efficient scanning mode. In this mode, the probe slides on the surface being measured, and the instrument will measure multiple times per second, capturing and displaying the minimum value during the measurement process in real time. This feature is useful for quickly identifying corrosion pits or large areas of corrosion薄Points are crucial. In addition, the instrument has a coupling status prompt function, and through the signal strength bar on the screen, users can intuitively judge whether the probe is in good contact with the workpiece surface, thereby ensuring effective readings.

Lightweight, durable, and long-lasting

The design of AD-3255 fully considers the requirements of on-site operations. The body is lightweight, weighing only about 160 grams (excluding battery), making it easy to hold or hang around the neck for long periods of time. It only uses two common AA (size 5) alkaline batteries for power supply, with a battery life of over 30 hours, avoiding the trouble of frequent battery replacement on site. The display screen has backlight function, making it convenient to read data in dark or low light environments.

In summary, AD-3255 has become a trusted daily tool for many non-destructive testing personnel and maintenance engineers due to its precise measurement capability, flexible probe configuration, user-friendly operation design, and sturdy portability.
