The TEM57MK2A and PROTEM receiver are the principal components of PROTEM 57 systems. The design and performance of the PROTEM 57 make it a highly portable, powerful and versatile time domain system.
The TEM57MK2A is powered by either a 600 W generator or by rechargeable batteries in a backpack. PROTEM 57MK2A systems are synchronized by either a reference cable or quartz crystal, usually determined by the size of the loop and whether they are being used for large loop soundings or profiling.
The PROTEM 57MK2A is used for a wide variety of applications. The system can sound the depth, thickness and conductivity of layers down to 300 m below surface, for applications such as mapping the thickness of aquifers, clay layers and assessing water quality. In coastal areas, the PROTEM 57MK2A has defined the depth to saline intrusion as accurately as chemical samples from wells.
The PROTEM 57MK2A, with a short reference cable, portable transmitter and 3-D receiver coil can delineate complex ore bodies within 200 m of surface. Deeper conductors can be characterised by profiling with a crystal synchronised receiver and a large, fixed transmitter loop. Modelling provides conductivity thickness, dip and extent of the ore body.
