Multipurpose Current Source
The T-3 is a lightweight, versatile multipurpose signal source for use in a variety of geophysical techniques. Weighing only 12 kg, it is easily transportable on a backpack over virtually any terrain. The T-3 can drive either inductive loads (loops) used in TDEM or FDEM techniques, or grounded dipoles used in IP, Resistivity, and CSAMT techniques.
Features T-3 Transmitter
Lightweight, highly portable
Operates at -20°C to +50°C
No cable links required between transmitter and System 2000.net receivers (V8, RXU)
Wide range of power sources:
50Hz or 60Hz motor generators or
32Hz to 16s (Time Domain);
~10kHz to 8s (Frequency Domain)
Phoenix design experience extends over 40 years, and the T-3 builds on this record. T-3 transmitters have been used in countless field surveys under every climatic condition worldwide.
Wide Range of Power Sources
The T-3 can be powered by one or more external 12 V batteries or by Phoenix's selectable-voltage BP-24/72 battery pack. Alternatively, the power source can be a standard geophysical motor generator, or any of a number of commercially available 50 Hz or 60 Hz motor generators. This flexibility means that the power source (and parts and service) can be obtained almost anywhere in the world.
The T-3 can be controlled by a System 2000.net RXU-TM transmitter monitor, with or without radio networking to a V8 receiver.
