Time Domain

EM System 

terraTEM provides a Time Domain EM (TDEM) transmitter and receiver in one unit with high speed sampling (500 KHz) with single or three channel (optional) receivers and a 10 amp transmitter.

The unit operates on a Pentium class processor and is controlled through a 38 cm. (15”) LCD ‘touch screen’ with a smart menu system and capability to display the data to conductivity depth-sections in the field.

The enhancements to the terraTEM include a high powered transmitter (50 amps), remote and downhole receivers and software.

terraTEM Features

• The internal transmitter provides 10 amp power (max. 240 watts) to the loop cable.  
• Built-in receiver provides high speed 500 kHz sampling, single input as standard.
• The user interface comprises a large 38 cm (15”) colour touch screen LCD monitor and provides full control of the acquisition display and processing of the TDEM data.
• Menus are designed to allow intuitive and rapid transition between acquisition parameters and data display. 
• The terraTEM is packaged with data reduction and processing software and can generate onsite standard profile and decay plots, apparent conductivity pseudo-sections and contour plan maps.  Images can be saved as bitmaps and inserted directly into reports.
• The terraTEM comes standard with three (3) sets of multiple time gates to 500 msecs delay.
• The gain functions on the terraTEM include 10 selectable gain settings from 1 to 8,000.
• The stacking options on the terraTEM are from 1 to 65,536 stacks.
• System parameters are stored automatically with each sounding for post-survey quality assurance.  
• Data is stored in a 4 GByte solid-state memory.  This provides the user with essentially unlimited storage space (up to 500,000 soundings).
• Data is transferred to a desktop PC and upgrades loaded by using a standard USB port.
• The terraTEM is powered by an external 24V battery pack allowing 6-8 hours of continuous operation.  
• All connectors are external to the case, allowing easy transportation without having to shutdown between sites.
