Wall Thickness ECHOMETER 1077 Data
High precision measurement with A-scan indication
The instrument uses single and dual element probes. Single element probes may be used with or without delay line.
Besides probes from the KARL DEUTSCH scope of delivery it is possible, in most cases, to use probes already available with the customer. Physical precondition for this is a broadband frequency response to generate clearly defined short pulse and echo signals.
In contradiction to conventionally designed gauges the A-scan and the measuring points contained therein can be used to judge especially well whether the probe is suitable for the given measurement task.
Measurement also on coated and multi-layer substrate
Quite often in materials testing, the specimens to be examined are protected by a varnish or plastics coating against environmental impact. Other materials in turn comprise several layers and the thickness to be measured pertains only to one of the different layers.
The ECHOMETER 1077 is able to measure most accurately through coated material and with multi-layer substrates, too:
By means of the BW-BW measuring method the measurement exclusively determines the transit time of successive back wall echoes or echoes generated by separating layers. This permits the determination of wall thickness also through coatings or separating layers providing high accuracy. Usually this only requires echoes of sufficient height at the separating transition zones.
Possible coating thickness:
A varnish or plastics layer thickness may have a 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 convenient menu guidance is selectable from many languages, is very user-friendly and appears in comprehensible plain language. Therefore the measuring parameters can be adjusted and modified very simply.
Understandable and plausible symbols inform on the current operating status.
In display mode “Measuring Result Only” three function keys with freely assignable menu topics are available.
Freely nameable folders and files assist with 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 in poor light conditions.
