Ultrasonic Sensor Thickness Gauge

An ultrasonic thickness gauge uses a piezoelectric wafer to emit high-frequency sound waves that travel through the material and reflect at interfaces. By measuring the time difference of the echoes and the material's sound velocity, the thickness is calculated. It is used to measure the thickness of materials such as metals and plastics, and finds applications in pipeline corrosion monitoring and plate quality inspection.
Selection
Select the probe frequency based on the material's sound velocity range: use 5MHz for conventional materials and 10MHz for thin materials. Consider the measurement range to cover the sample thickness, with accuracy required to meet ±0.1mm. Choose a high-temperature probe for high-temperature environments and a small-diameter probe for curved surface measurements. The operation interface should be simple and support calibration functions.
