Ultrasonic Wall Thickness Measurement
Ultrasonic thickness measurement techniques are used to measure a wide range of substrates and applications for loss of material thickness due to corrosion or erosion. Ultrasonic Thickness Gauges are designed for measuring the thickness of metallic (cast iron, steel, and aluminum) and non-metallic (ceramics, plastics, and glass) substrates and any other ultrasonic wave-conductor provided it has relatively parallel top and bottom surfaces.
An ultrasonic thickness gauge facilitates rapid inspection of the thickness of large metallic structures at small measurement intervals, providing a high-detail thickness map of a scanned surface. When access is only available from one side of the substrate, ultrasonic wall thickness measurement is the most efficient way to monitor the effects of erosion or corrosion and is instrumental to both quality assurance and quality control.
Ultrasonic Thickness Gauges – Corrosion
PosiTector UTG C Series
Corrosion probes measure the wall thickness of materials such as steel, plastic, and more. Ultrasonic Thickness Gauges are ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side.
