Universal Wall Thickness Measurement Gauge

Ultrasonic thickness gauges are used to measure the thickness of materials from one side by means of ultrasound. An ultrasound tranducer generates a high-frequent ultrasound pulse which is sent through the material to be measured. At the backside of the material the pulse is reflected and travels back to the transducer. As the material and its sound velocity is known the travel time of the pulse is used to calculate the material thickness. Wall thickness gauges are often used to determine the amount of corrosion on ships or at pipeline tubes.

The DC-2000C is an universal gauge for metallic and non-metallic materials, e. g. steel, aluminium, cast iron, glass, ceramic, plastics. The gauge is characterized by high accuracy and with an easy-to-use menu structure. The sound velocities of nine different materials are stored in the gauge. The gauge allows also the storage of four user-defined sound velocities, resulting from numerical input or built-in sound velocity measurement.

The measurement process is simple: after selecting the material or the sound velocity the probe will be placed on the measuring spot which was prepared beforehand with a small amount of couplant. A symbol in the display signals a successful pairing  and the wall thickness is shown.

Different probes for different applications are available including a special high-temperature probe which allows measurements up to 350°C.
