General Information

Phoenix offers a range of electrical and magnetic sensors for MT and AMT data acquisition.

MT, AMT, CSAMTMagnetotellurics (MT), Audio MT, and Controlled Source Audio MT in scalar, vector, and tensor modes
TDEM, FDEM, MulTEM, LowTEMAll common Time and Frequency Domain Electromagnetics functions


All Phoenix field sensors are highly reliable, lightweight, and manufactured to exacting standards. Designed for use in the most demanding environments, they have proven their reliability and quality on many thousands of surveys around the world.

Combined with the V5 2000 System or System2000.net insrtuments, they provide excellent data quality over a wide range of frequencies.

AMTC-30 magnetic sensor coils are used for AMT magnetic data acquisition. Weighing about 3 kg and measuring only 82.5 cm, AMTC-30 sensors are compact and portable while providing high-quality magnetic data at frequencies between 10 000 Hz and 1 Hz.
MTC-50H magnetic sensor coils weigh approximately 8 kg, and measure only 144 cm. They provide magnetotelluric data at frequencies up to 400 Hz and down to 0.00002 Hz (50 000 seconds). As of 2010, the MTC-50H replaces the older MTC-50 sensor.
MTC-80H magnetic sensor coils are the newest addition to the induction coil family. Intended for use in MT surveys to moderate depth, they weigh about 5 kg (half the weight of the MTC-50H) and measure 97 cm in length (70% of the length of an MTC-50H). The MTC-80H provides good data from 400 Hz down to 10 000 seconds, depending on signal strength and local conditions.
  Note: The lengths given above include the PVC cylinder that slides on to the sensor to protect the connector; the cylinder is not shown in the photographs.
AL-100 The airloop model AL-100 is specially designed for vertical magnetic field MT measurements in stony and hard ground, where it is difficult to dig a hole for a vertical coil.
