WTEM-2 Medium-Deep/Deep TEM Exploration System is applicable to medium-deep/deep transient electromagnetic exploration, one of our latest researches, with all functions of transient electromagnetic survey system. It boasts high power, short turn off time, high reliability, strong anti-interference performance (against atmospherics, 50Hz or 60 Hz industrial frequency interference), lightweight and low power consumption.

It is composed of WTEM-2J TEM Exploration System Receiver, WTEM-1D 10Kw High-power Transmitter or WTEM-1Z 6kw transmitter, WTEM-2T/GPS Transmitter Synchronized Controller or WTEM-1T/GPS Synchronized Controller and one PDA. In addition, the optional instrument is PTT-40A Antenna & Adapter.

Main functions and features:

All-round optimization of WTEM-2J receiver: compared with WTEM-1J receiver, the front panel is nicer. Except for the power switch, all other operations are carried out through a pocket PC.

Improved WTEM-2T/GPS transmitter synchronized controller: a better GPS module and antenna of higher sensibility is integrated, faster in synchronization speed, compacter in size and lighter in weight.

Support several synchronization mode: in addition to cable synchronization, GPS synchronization, and an extra “GPS + Clock” synchronization mode is compatible (optional). This function helps when GPS satellite signal is very weak or disappears for the high-precision and high-stability quartz crystal will help to perform synchronizing with error less than 1 us/hour. Once start up, it only takes no more than 2 minutes to get the transmitter and the transmitter synchronized if satellite signal is good.

High reliability, low power consumption: refined receiver and circuitry, sealed and r ed mechanical structure, ensuring high reliability, low power consumption and convenient operation.

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.

Remote control: it is the first receivers that take use of a pocket PC and Bluetooth wireless communication technology which enable it to control the WTEM-2J receiver 10 meters, such as setting up 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-to-depth ratio. Sampling window arrangement is reasonable, imaging the true subsurface structure. It provides references to complex geological problems.

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.

Friendly and powerful control interface: PDA control and collects data from human-machine interface, such as parameters input, data display or storage, graph plotting, etc, simplifying fieldwork.
