500m 1000m Surface TDEM Equipment Transient Electromagnetic Survey System Apparent Resistivity Tem Soundings Device For Deep Water and Mineral Exploration
Standard configuration of WTEM-2 system:
WTEM-2] TEM Exploration System Receiver
WTEM-1D 10kw High-Power Transmitter
WTEM-2T/GPS Transmitter Synchronized Controller
Tablet computer to control the TEM system receiver and the system.
Optional instruments:
PTT-40A Antenna & Adapter
WTEM-2] receiver has to work together with a WTEM-1D transmitter to finish medium-deep or deep sounding; in the mode of GPS synchronization, a WTEM-2T/GPS synchronized controller is needed to synchronize WTEM-2J receiver and the transmitter. PTT-40A Receiver Antenna & Adapter is a specific antenna (or receiving coil) designed for TEM system receiver, which consists of an detached antenna and adapter, with large equivalent area and high signal-to-voice ratio, easy for field layout and free from limitation of landform.
Loop applicable may be central loop or coincident loop, one TEM system transmitter working together with one TEM system receiver; or be large loop, one TEM system transmitter in association with several TEM system receivers. According to different geological situations, user could choose an appropriate system to finish surveying tasks of quick general survey, 3D graph coloring up, deep mine finding.
It is mainly used for surveying metal mine, coal-mine, oil and gas field, geothermal field, and applies in hydrology and engineering geological prospecting as well.
