Description
The MPTX-500 is a high current EM transmitter designed for ultra-high resolution, small, Fixed Loop EM surveying. It has particular application as a component of a Deep Search UXO detection system.
Purpose
Conventional UXO search instruments typically have a detection depth capability of 1 - 2m and are therefore generally only suitable for locating shallow items of ordnance. However, large items such as aerial bombs may penetrate to depths which are well beyond the detection limit of conventional technologies.
This concept transmitter was developed in collaboration with the US Army Corps of Engineers (Huntsville) for unexploded ordnance detection as part of an ESTCP funded Research project. Used in conjunction with Gap’s Sub-Audio Magnetics (SAM) technology, the MPTX-500 may facilitate detection depths of up to 10m for large aerial bombs. This technology has significant future application in the remediation of formerly used Defence sites or war-torn areas.
Performance
The MPTX-500 is capable of outputting up to 500A into a 40m x 40m loop.
-
up to 350 Amps in a 100m x 100m loop
-
shutoff < 40µs
-
synchronised with GPS time strobes
-
constant current and controlled current modes
-
can be operated remotely using a PDA and bluetooth communications
-
control software allows monitoring and display of all Tx functions.
The performance of the MPTX-500 can be modelled for various loop configurations using GapTxCalc.
