Magnetic Survey Instruments For deep Geophysical Exploration
Magnetic survey instruments are used to measure the variations in the Earth's magnetic field caused by geological features such as mineral deposits, faults, and other subsurface structures. These instruments work by measuring the strength and direction of the magnetic field at a specific location.
Standard configuration of WTEM-2 system:
WTEM-2J TEM Exploration System Receiver
WTEM-1D 10kw High-Power Transmitter
WTEM-2T/GPS Transmitter Synchronized Controller
Pocket PC (PDA) to control the TEM system receiver and the system.
Optional instruments:
PTT-40A Antenna & Adapter
WTEM-2J 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.
