There are two types of thickness gauging: ultrasonic and x-ray. The ultrasonic type measures by touching the sensor to the object to be measured. The X-ray type measures by the amount of X-rays transmitted through the sensor, so it does not need to be in contact with the object.
Since there is no need for contact, X-ray sensors are used in manufacturing equipment to measure objects that are continuously produced. In addition, there are various methods to measure the thickness of films such as plating and coating, depending on the material of the base material and film, and the thickness of the thin film. There are optical, electromagnetic, eddy current, infrared, ultrasonic, X-ray, and other types of film thickness gauges.
Matsusada Precision manufactures and sells power supplies and X-ray sources used in the development, manufacture, and integration of these thickness gauges and film thickness gauges.
