Product information "Sauter TN 30-0.01EE echo-echo ultrasonic material thickness gauge, 3 to 30 mm / 0.01 mm"
The Sauter TN series comprises handheld ultrasonic measuring devices for measuring the thickness of a workpiece from just one side. An external probe transmits ultrasound into the material; the device calculates the wall thickness based on the transit time. The series comprises eight models: five pulse-echo devices for metals and plastics (TN 80-0.01US, TN 80-0.1US, TN 230-0.01US, TN 230-0.1US, TN 300-0.01US), two devices with an additional echo-echo mode for coated parts (TN 30-0.01EE, TN 60-0.01EE) and the TN GOLD 80, a gold tester. All are battery-operated and, at 150 x 74 x 32 mm, fit in one hand.
Pulse-echo or echo-echo
In pulse-echo mode, the device measures the total thickness, including any coating. According to Kern, the echo-echo models TN 30-0.01EE and TN 60-0.01EE determine the actual material thickness independently of any existing coating. This allows, for example, the wall thickness of pipes to be measured non-destructively without removing the coating. The device can display the measured value already corrected for coating thickness. Echo-echo measurements only work with the supplied ATU-US12 probe. The echo-echo range is from 3 to 30 mm for the TN 30-0.01EE and from 3 to 60 mm for the TN 60-0.01EE. In pulse-echo mode, both measure from 0.65 to 600 mm.
Probe, frequency and range
Range and probe belong together. The probe of the TN 300-0.01US operates at 2.5 MHz, has a diameter of 14 mm and measures from 3 to 300 mm. Both TN 230 models have a 5 MHz probe with a diameter of 10 mm and measure from 1.2 to 230 mm. The two TN 80 models and the TN GOLD 80 have a 7 MHz probe with a diameter of 6 mm and measure from 0.75 to 80 mm. The two TN 80 models and the two TN 230 models each differ in readability (0.01 mm versus 0.1 mm) and in the interface: the models ending in 0.1US (TN 80-0.1US, TN 230-0.1US) do not have a USB port. The sound velocity ranges from 1,000 to 9,999 m/s; Kern specifies the measurement accuracy as 0.5 % of Max ± 0.04 mm.
Measuring modes, memory and data transfer
With the exception of the TN GOLD 80, the models can measure either in scan mode at 10 measurements per second or at a single measurement point. On all models, the internal memory can store up to 20 files, each containing up to 100 individual values. The unit is mm or inches. With the exception of the TN 80-0.1US and the TN 230-0.1US, all models have a USB interface. The LCD display features 14 mm high digits. According to the data sheet, two AA batteries last for approximately 100 h.
TN GOLD 80: authenticity testing of gold
The TN GOLD 80 is part of the series but serves a specific purpose. It tests gold bars and gold coins for counterfeit cores, such as those made of tungsten or lead. To do this, it measures the thickness using ultrasound and compares the result with the thickness traditionally determined using a calliper. According to Kern, counterfeit cores can be identified by the fact that the ultrasound behaves differently to that in pure gold. The supplied Sauter SSG software calculates the sound velocity in various precious metal alloys. It compensates for known admixtures such as copper or silver, and also determines the value of the gold item. According to Kern, the method performs a non-destructive test through the entire ingot or coin.
Typical applications
- Metalworking and mechanical engineering: wall thickness of sheet metal, tubes and castings
- Oil and gas industry: wall thickness inspection on pipework, including under coatings (echo-echo)
- Aerospace: thickness measurement on components from one side
- Plastics engineering: wall thickness of plastic components
- Shipbuilding industry: plate thickness and corrosion checking on hulls
- Jewellery industry and gold dealers: authenticity testing of bars and coins with the TN GOLD 80
For thin walls from 0.75 to 80 mm, one of the two TN 80 models is sufficient; for measuring ranges up to 230 mm with a readability of 0.01 mm, the TN 230-0.01US is sufficient. For measuring thicker workpieces up to 300 mm, use the TN 300-0.01US; for inspecting coated tubes, use one of the two EE models.
