The thickness gauge is a measuring device with which you can measure the thickness of various parts, materials. Thickness gauges often measure products made of hard and soft materials, wood, paper, rubber, etc. The thickness gauge is a simple and reliable device for making quick measurements in production. Thickness gauges are divided into several types of work, their application, as well as the method of measurement.
- Mechanical
- Digital
- Ultrasonic
Mechanical thickness gauges or wall gauges have a round scale that can be set to "0" by turning. The devices are easy to use, give the opportunity to get the measurement result in a matter of seconds. Indicator thickness gauges have a division value of 0.01, increased accuracy of 0.001
Digital instruments have an electronic display that allows you to see the measurement result in a matter of seconds.
Ultrasonic thickness gauges - they are characterized by the presence of an ultrasonic sensor in the measuring probe, which sends a pulse through the measured (analyzed) coating. The pulse is reflected from the surface and then converted by the sensor into a high-frequency electrical signal. The signal echo is digitized and analyzed to determine the thickness of the coating
