Thickness Gauge FAQ

1. What is a thickness gauge?

A thickness gauge is an instrument used to measure the thickness of various materials, inclusiv metalele, materiale plastice, acoperiri, și compozite. These gauges are crucial for quality control, helping ensure materials meet industry standards for thickness and uniformity. Thickness gauges are widely used in industries like manufacturing, auto, aerospațială, and construction to verify the integrity of materials and identify potential defects.

2. How do ultrasonic thickness gauges work?

Ultrasonic thickness gauges use high-frequency sound waves to measure the thickness of a material. A transducer emits sound pulses into the material, and the gauge measures the time it takes for the sound waves to reflect back from the far side of the material. This method is highly accurate and can measure the thickness of metals, materiale plastice, and other solid materials without damaging them.

3. How much does a thickness gauge cost?

The price of a thickness gauge depends on factors such as the type of material being measured, the required precision, and the additional features (such as data logging or connectivity). Basic models may start at a few hundred dollars, while advanced models for specialized applications can cost significantly more.

It allows for non-destructive testing of both the coating and the base material, making it ideal for industries where coatings must remain intact, like shipbuilding and oil & gaz.

7. What is the difference between ultrasonic and coating thickness gauges?

Ultrasonic thickness gauges measure the thickness of solid materials such as metals, materiale plastice, și compozite, in timp ce coating thickness gauges measure the thickness of surface coatings, like paint or varnish. Ultrasonic gauges are used when the material itself is of interest, whereas coating gauges focus on the protective layers applied to substrates.

8. How do you measure plastic thickness?

Plastic thickness can be measured non-destructively using either cu ultrasunete sau Hall-effect thickness gauges. Both methods are suitable depending on the application, but ultrasonic gauges are commonly used to measure solid plastics, while Hall-effect gauges are ideal for thin, flexible materials like plastic films.
