MultiX-LF Low-frequency High-power
Maker:M2M
The MultiX-LF is a unique phased-array system optimized for low-frequency applications. It is ideal for applications on highly attenuative/heterogeneous materials such as thick composite, concrete and casted steels.
Due to its full parallel architecture the system can send and receive on all array elements of the probe simultaneously. High voltage pulses can be generated in a broad band in the low frequency range, with multiple pulse modulation possibilities.
A broad range of available configurations from 16 to 64 parallel channels covers a large range of potential applications. MultiX-LF systems can be used with virtually every commercially available linear and matrix array probe. All standard test methods are supported, such as pulse-echo and transmit-receive mode, TOFD and dual element measurements.
