Ancillary Components

terraTX-50 High Power Transmitter

For high-power applications, an external transmitter, the terraTX-50, is available.  The terraTX-50 delivers up to 50 amps at 100V and can be synchronised by either reference cable or GPS timing.  It is controlled by the terraTEM.

• High Powered Transmitter for use with terraTEM Receiver
• Battery or Rectifier (for Generator) Powered
• Selectable Range of Voltages
• Up to 50 Amps (5 kW) output
• Cable or GPS Synchronisation
• Very low turn-off times
• Compact and light weight
• Designed and built in Australia

TRC-1 & 3 Time Domain Remote Receivers

• The single or three component TRC-3 is a result of 18 years of experience in building multi-turn TEM receiver coils
• A large active area reduces the amplification required to make an acceptable effective area
• Bandwidth and speed of response can be varied to suit particular requirements
• Rugged construction
• Easy to service on the rare occasion it is needed

VecTEM 4 Time Domain Downhole Receiver

The VecTEM 4 probe compliments the range of terraTEM instrumentation to provide downhole information with the terraTEM transmitter and acquisition system.

• The three (3) component Downhole Receiver allows for improved ability to detect anomalies and position any previously observed targets
• Designed for easy operation with the terraTEM recording unit
• Orientation of the probe is measured to collect true X-Y-Z data
• Also measures the dip angle of the borehole at any depth
• Rugged construction 
• Uses 4 conductor cable with standard fittings (allowing attachment to most downhole logging winches)
