Product information "Sauter TO 100-0.01EE echo-echo ultrasonic material thickness gauge, 3 to 100 mm, TFT colour display"
The Sauter TO 100-0.01EE measures the wall thickness of coated metal parts without the need to remove the coating. The ultrasonic material thickness gauge has two modes for this purpose: echo-echo from 3 mm to 100 mm and pulse-echo from 0.7 mm to 600 mm. It has a TFT colour display, memory for 100 data sets and a USB interface. The ATU-US12 probe (5 MHz, Ø 10 mm) is included in the scope of delivery.
Echo-echo: material thickness under paint and corrosion protection
In echo-echo mode, according to Kern, the device determines the actual material thickness independently of any existing coating, such as paint or an anti-corrosion layer on the base metal. This allows the wall thickness of pipes to be measured non-destructively. The measured value appears on the display, already corrected for the coating thickness. According to Kern, the device measures not only metal but also plastics, ceramics, composite materials, epoxy and glass. In pulse-echo mode, the TO measures the total thickness up to 600 mm.
Measuring modes and adjustment
There are three measuring modes. Standard mode records one data point. Scan mode measures continuously and displays the current value as well as the minimum and maximum values of the measurement series. Difference mode shows the deviation between the actual value and a manually set nominal thickness. Three adjustment methods are available: automatic zero-point adjustment, single-point adjustment to a specific material thickness, and two-point adjustment using two known material thicknesses. In high-precision mode, the readability can be switched from 0.1 mm to 0.01 mm. The sound velocity ranges from 200 to 19,999 m/s.
NT measurement technology
Kern describes the TO as a device representing the new generation of NT measurement technology. An automatic sensor adjustment (V-path correction) is intended, according to Kern, to improve accuracy and speed up the display. Kern specifies the measurement accuracy as 0.4 % of Max ± 0.04 mm.
Display, memory and limit values
The TFT colour display (320 x 240) has adjustable brightness. The memory can store up to 100 data sets, each containing 100 individual values; each measured value can be assigned a timestamp, and the date and time are adjustable. The data can be downloaded to a PC via USB. A limit value alarm function emits an audible and a visual signal when the programmed upper or lower limit value is reached. The menu languages are German, English, French, Spanish and Italian.
Battery and housing
According to Kern, two AA batteries last for at least 30 h. The time until automatic switch-off (sleep) and the display switch-off (standby) are adjustable. The plastic housing measures 31 x 69 x 130 mm and weighs approx. 0.25 kg.
Typical applications
- Oil and gas industry: wall thickness of painted or corrosion-protected pipework
- Metalworking and mechanical engineering: thickness of coated components, without removing the coating
- Shipbuilding: plate thickness on painted hulls and tanks
- Aerospace: thickness measurement on components, including those made of composite materials
- Plastics engineering: wall thickness of plastic components
The TO is suitable when coatings are to remain on the workpiece. For measurements without coating up to 80 mm, the TU 80-0.01US also suffices, the TN series covers further ranges, both also available.
