1、 Technical principles

The multi-channel ultrasonic thickness gauge emits ultrasonic pulses simultaneously through multiple probes (channels). When these pulses propagate inside the measured object, they will be reflected back to the probe when encountering the back of the material or the interface between different materials. The device calculates the thickness of the object being measured by accurately measuring the time required for ultrasonic waves to propagate from transmission to reception (propagation time), and combining it with the known sound velocity (the speed at which ultrasonic waves propagate in the material) using a formula. The multi-channel design enables the device to process data from multiple measurement points simultaneously, significantly improving detection efficiency.

2、 Core functions

Multi channel synchronous measurement: supports multiple probes working simultaneously to achieve multi-point synchronous thickness measurement, suitable for rapid detection of large areas or complex structures.

High precision measurement: The measurement error is usually controlled within a very small range (such as ± (0.5% H+0.05) mm, where H is the thickness of the measured object) to ensure the accuracy of the measurement results.

Adjustable and reverse measurement of sound speed: supports manual adjustment of sound speed to adapt to different materials, and has the function of reverse measurement of sound speed. It can measure the sound speed of an unknown object based on its thickness.

Data storage and management: Built in large capacity storage, capable of storing a large amount of measurement data (such as 200 data per group, a total of 10 groups), supporting data viewing, deletion, printing, and computer communication operations.

Multiple measurement modes: including conventional measurement, minimum value scanning, monitoring measurement, and scanning measurement, to meet the needs of different work sites.

Environmental adaptability: Suitable for harsh operating environments, with the ability to resist vibration, impact, and electromagnetic interference.

3、 Application scenarios

Multi channel ultrasonic thickness gauges are widely used in multiple fields, including but not limited to:

Petroleum and chemical industries: used to monitor the degree of thinning of equipment such as pipelines and pressure vessels after corrosion during use, ensuring the safe operation of the equipment.

Metallurgical and shipbuilding industries: measure the thickness of metal materials such as steel plates and pipes to control product quality.

In the fields of aviation and aerospace, thickness testing is conducted on key structures such as aircraft skins and engine components to evaluate their safety performance.

Power industry: Monitor the wall thickness of equipment such as boilers and turbines to prevent accidents.

Ceramic and glass manufacturing industry: Accurately measure the wall thickness of ceramic and glass products to ensure that they meet design requirements.

4、 Advantage analysis

Efficiency: Multi channel synchronous measurement significantly improves detection efficiency and shortens detection time.
