Wall Thickness ECHOMETER 1076 TC
+ Statistics Evaluation + Data Storage + PC-Interface, for coated materials
Using the standard method (TP-BE mode) for measurement of wall thickness and sound velocity the probe is placed on the uncoated surface of the material.
The ECHOMETER 1076 TC offers more: Varnish or plastics coatings up to 4 mm thickness can be blanked out so you can measure highly precise also through the coating. Then the measuring result is calculated by means of successive back wall echoes.
Depending on the probe the measuring range for wall thickness covers 0.5 to 400 mm. The measurement of sound velocity in sound conductive material copes with a measuring range from 100 to more than 20,000 m/s without any problems.
Besides a standard probe for the most common wall thicknesses from 1.2 to 250 mm a high-resolution probe for thin-walled workpieces from 0.5 to 25 mm and a low frequency probe for wall thicknesses up to 400 mm are available.
The standard probe BE-BE can be used either for measurements using the TP-BE method (measuring range: 2 – 250 mm) or for through coating measurements (measuring range: 2 to 28 mm).
The connected probe is automatically recognized by the gauge.
Measurement also through coatings
Quite often in materials testing, the specimens to be examined are protected by a varnish or plastics coating against environmental impact.
With the standard measurement method (TP-BE) the ultrasound transit time between transmitter pulse and first back wall echo is measured. In this case, if you do not want to damage the protective layer, you have to rely on an estimation of the layer properties so the determined results will be correspondingly inaccurate.
The ECHOMETER 1076 TC is able to measure most accurately through coated material, too:
By means of a special measuring method (BE-BE) which exclusively determines the transit time of successive back wall echoes you are able to measure the wall thickness also through a coating with high precision.
This mode copes with a varnish or plastics layer thickness of up to 4 mm. However, in real life coatings of up to 8 mm thickness often do not pose a problem (depending on material).
Operating menu and indication of measuring results
The easy and comfortable menu navigation is very user-friendly and appears in a comprehensible plain language. Therefore the measuring parameters can be adjusted and modified very simply.
Understandable and plausible symbols inform on the current operating status.
Freely namable folders and files assist with the data storage, just as you are used to on a PC.
The readings are displayed in large and clear digits, optionally together with the current statistics data.
A backlight illumination of the display ensures a convenient operation also for poor light conditions.
