This system is one of our latest researches, with all functions and 

advantages of domestic and oversea shallow transient electromagnetic 

survey systems, integrated with WTEM-1J/GPS TEM system receiver and 

WTEM-1X low-power transmitter. It features high transmitting power, 

short turn-off time, high reliability, strong anti-interference 

performance (atmospherics, 50Hz or 60Hz industrial frequency 

interference), lightweight and low power consumption.

According to different geological situations, user could choose an 

appropriate system to finish surveying tasks of quick general survey, 

3D graph coloring up, stereo mapping, deep mine finding and shallow 

sounding. It is mainly used for surveying metal mine, coalmine, oil 

and gas field, geothermal field, and applies in hydrology and 

engineering geological prospecting as well.

Main functions and features:

One instrument with multiple functions: this system is integrated with 

functions of a transmitter and a receiver, portable and simple in 

connection. The receiver alone could synchronize though cable, GPS and 

thus associated with the external high-power transmitter to fulfill 

deep exploration.

High reliability, low power consumption: refined receiver and 

circuitry, reasonable heat dissipating system design, sealed and 

r ed mechanical structure, ensuring high reliability, low power 

consumption and convenient operation.

Remote control: PDA based Bluetooth wireless communication technology 

enables it to control the receiver in 10 meters, such as setting 

parameters, starting measuring, transferring and displaying the 

measured results.

High anti-interference performance: program controls the filter to 

give accurate power supply frequency; besides, data stacking and 

software filtration also do good to this performance.

Multiple channels, high measurement accuracy: operator could set 

number of channel, linear or logarithmic; crystal oscillator 

accomplishes timing, with stable and precise time–depth ratio. 

Sampling window arrangement is reasonable, imaging the true subsurface 

structure. It provides references to complex geological problems.

Short turn-off time: transmitter supports swift turn-off function, 

able to extend shallow exploration range. Short turn-off function 

provides software with accurate turn-off time to enable it to give 

accurate data.

Wide depth range prospecting: this system is equipped with high-power 

transmitter which could reach in meters to thousands of meters (deep 

exploration)

Friendly and powerful control interface: PDA controls and collects 

data from human-machine interface, such as parameters input, data 

display or storage, graph plotting, etc, simplifying fieldwork.
