CUGTEM-4 Deep Resource Exploration TEM Instrumnent

with the detecting depth from 50M to1300M CUGTEM-4 can be used for underground polymetallic deposit and water search, salt and fresh water distinction, underground electricproperty stratification, underground water-filled cave delineation and steep angle geological structure detection, Particularly applicable to the coal seam, coal mined-out ares (collapse areas), and water-filled area detection. The effects are so perfect that all the users praise it very much. In addition, this instrument also has realized ideal application effect in other aspects.
The CUGTEM_4 receiver's appearance structure design is compact, it is a military IPC and has the manerverable windows chinese operation platform. The display adopts the reflecting LCD, the power consumption is very low, it can work under the projectivity sunlight and is very suitable for the field open-air operation. the receiving circuit is assembled with the latest high-performance chip, the stableness and security are favourable. The maximum sampling rate can reach 1¥Ìs, it adopts the total area high-density data to sample the power supply current and the voltage value of the secondary magnetic field, the massive data obtained provide a good foundation for the digital filter, time setting, turn-off time correction, and the detail research of abnormal forms, etc.
CUGTEM_4 transmitter first grasps the original technique to supply power with 200A high-current continuous square wave in domestic and foreign lightweight TEM instrument's transmitting system.Adopts the lightweight electrical source to realize power supply with the high current , the big-power, positive and negative square wave, and realize the multi-superposition.Takes big current and small coil for power supply, merging with the advantages of power supply with tradional method, the detecting depth can reach to kilometers, it's very suitable for the operation under abominable field conditions, the field operating expenses and the time can be saved to a large degree vs the traditional large coil method, obviously improves the field operating efficiency. The side length of transmitting loop can be dramatically reduced for the same detecting depth due to the increase of transmitting current.
