 EM-37 Transmitter plus Generator

The TEM37 is the most powerful transmitter used with the PROTEM receiver forming the basis of the PROTEM system.

The high powered TEM 37 can be used to sound to depths greater than 1 kilometre, and in the large fixed loop profiling mode, detect and delineate ore bodies at over 500 metres.

The transmitter and receiver in a PROTEM 37 system are equipped with quartz crystals for synchronization, although a reference cable can be used if transmitter-receiver separation is less than 200 m. The TEM37 is powered by a specialized motor-generator, which can energize loops up to 2000 x 2000 m in size.

The PROTEM 37 is used to profile deeply buried conductors, which makes the system a principal tool of mineral exploration. Both the 3-D receiver coil and BH43 borehole probe are used routinely with the system. The PROTEM 37 also enjoys widespread application for deep soundings for groundwater exploration, mapping saline intrusion, and for geothermal exploration as well as general regional geological research where structures and layers can be detected at depths greater than 1000 m.
