Wall thickness measurement using the DMS Go+
1-16
Edition 4 (05/2014)
DMS Go+
Dual mode (measurement mode DUAL)
In the dual mode, the tasks of transmitting (T) and re-
ceiving (R) are solved by two transducer elements ar-
ranged in such a way that they are mechanically sepa-
rated from each other. An initial pulse is triggered on the
transmitter side and transmitted to the test object. The
echoes are received on the receiver side and reconvert-
ed into (very weak) electric pulses.
The DMS Go+ measures the time between transmitting
and receiving the sound pulse (time of flight). The DMS
Go+ determines the material thickness on the basis of
the measured time and the material's sound velocity.
The operating principle of a dual-element probe is
shown in the following figure.
