Product information "Sauter TU 80-0.01US pulse-echo ultrasonic material thickness gauge, 0.75 to 80 mm / 0.01 mm"
The Sauter TU 80-0.01US is an ultrasonic material thickness gauge in a die-cast aluminium housing designed for the pulse-echo method. It measures from 0.75 mm to 80 mm with a readability of 0.01 mm. The external probe operates at 7 MHz and has a diameter of just 6 mm, which means it can also be used on small and thin components. The workpiece need only be accessible from one side.
Pulse-echo measurement with a small probe
In the pulse-echo method, the probe transmits an ultrasonic pulse into the workpiece and measures how long it takes for the echo to return from the rear wall. The device uses this to calculate the thickness. This requires the sound velocity in the material; the device covers a range from 1,000 to 9,999 m/s. Kern states a measurement accuracy of 0.5 % of Max ± 0.04 mm. The pulse-echo method measures the total thickness, including any coating; the TU does not have an echo-echo mode.
Scan mode, limit values and memory
The device measures either in scan mode at 10 measurements per second or at a single measuring point. For series testing, upper and lower limit values can be programmed, whilst an audible and a visual signal assist with the measurement. The internal memory can store up to 20 files, each containing up to 100 individual values. The data is transferred to a PC via the USB interface. The unit is mm or inches. The zero plate for adjustment is included in the scope of delivery.
Robust construction
The die-cast aluminium housing measures 132 x 76 x 32 mm and weighs approx. 0.50 kg. According to the data sheet, it operates at ambient temperatures ranging from -10 °C to 60 °C. Two AA batteries provide power for around 100 h of operation; the probe is attached to a 0.9 m long cable.
Typical applications
- Metalworking and mechanical engineering: wall thickness of thin sheets, tubes and castings
- Oil and gas industry: wall thickness inspection of pipes and vessels
- Aerospace: thickness measurement on sheet metal and lightweight components
- Plastics engineering: wall thickness of plastic components
- Shipbuilding industry: thickness inspection of sheet material
The TU 80-0.01US suits workpieces up to 80 mm where a small probe is needed. For greater thicknesses up to 230 or 300 mm there is the TN series, for coated pipes the echo-echo model TO 100-0.01EE, both also available.
