Product Description

   Geophysical Transient electromagnetic (TEM) sounding  Time-Domain EM Transient Electromagnetic Method              TEM Equipment Deep Transient Electromagnetic System(TDEM)


 

Geophysical Transient electromagnetic (TEM) sounding  Time-Domain EM Transient Electromagnetic Method TEM Equipment Deep Transient Electromagnetic System(TDEM)

TEM methods have been used in mineral exploration for more than half a century and are now used for an extremely broad range of applications in exploration, engineering, and environmental investigation.

The depth of investigation can vary from 10s of meters to over 1000 meters (30 to 3,000 feet), depending upon the size of the transmitter loop being used, available power from the transmitter, and ambient electromagnetic noise.  a fast-turn-off variation of TEM for very shallow surface applications (<5 meters).

Main Functions and Features
Geophysical Transient electromagnetic (TEM) sounding  Time-Domain EM Transient Electromagnetic Method TEM Equipment Deep Transient Electromagnetic System(TDEM)

1. All-round optimization of WTEM-2J receiver: Except for the power switch, all operations are carried out in pocket PC through Bluetooth.
2. Improved WTEM-2T/GPS transmitter synchronized controller: a better GPS module and antenna with higher sensibility, faster in synchronization speed, compacter in size and lighter in weight.
3. Support several synchronization mode: 
   1. 1.  cable synchronization
      2.  GPS synchronization
      3.  "GPS + Clock" synchronization (optional)
      4. When GPS satellite signal is very weak or disappears, the quartz crystal will perform synchronization with error less than 1μs/hour.

The latter two synchronization modes require a WTEM-2T/GPS synchronized controller. Once start up, it only takes no more than 2 minutes to get the transmitter and the transmitter synchronized if satellite signal is good.

Geophysical Transient electromagnetic (TEM) sounding  Time-Domain EM Transient Electromagnetic Method TEM Equipment Deep Transient Electromagnetic System(TDEM)

1. High reliability, low power consumption: refined receiver and circuitry, sealed and rugged mechanical structure, ensuring high reliability, low power consumption and convenient operation.
2. Wide range of sounding depth: WTEM-1D transmitter can help to perform medium-deep or deep exploration in tens of meters to thousands of meters.
3. Remote control: pocket PC and Bluetooth wireless communication technology enable to operate the WTEM-2J receiver in 10 meters, such as setting up parameters, starting measuring, transferring and displaying the measured results.
4. 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.
5. Multiple channels, high measurement accuracy: operator could set number of channel, linear or logarithmic; crystal oscillator accomplishes timing, with stable and precise time-to-depth ratio. Sampling window arrangement is reasonable, imaging the true subsurface structure. It provides references to complex geological problems.
6. Short turn-off time: transmitter support 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.
