ERP-1
Portable digital electrical exploration system ERP-1 is designed for geophysical survey performed by the following methods
Electrical exploration by DC and AC resistivity method - vertical electric sounding (VES), electric profiling, signal generator, МЗ, as well as measuring of the full vector of an electric field: magnetomotive force, vector survey
Natural electric field (self-potential, measuring of stray current field) method
Induced polarization (IP) with INFAZ-VP version
APPLICATIONS
geological mapping
cryopedology
search and exploration of mineral deposits
geoecology
archeology
geological engineering
applied geophysics
hydrogeology
The system ERP-1 provides a combination of analog and digital signal processing. To ensure accumulation in the signal processing measuring unit there are synchronized filters furnished on switched capacitors
FEATURES
the system ERP-1 provides a complex of electrical exploration methods that extends the range of solvable problems and improves the quality and accuracy of obtained results
the system has high noise immunity (good quality of measuring unit narrow-band analogue filter is 18), that is required for urban development, sites near electricity transmission lines, railways, etc.
survey results, including the number of profile, survey stake, span, measurement date and time, are stored in memory
the system ERP-1 is provided with software for data transfer from measuring unit to PC and storage of measurement results in formats compatible with software package IPI2WIN (VES and VES-IP data processing and interpretation, developed by Moscow State University )
"digital" area of signal processing contains an additional method of hardware noise reduction
transmitter ERP-1 is supplied with two outputs, a switch tumbler for operation with different supply lines (i.e., for double-differential profiling)
receiver ERP-1 is supplied with two inputs,a switch tumbler for operation with different receiving lines (i.e., vertical electric sounding with "collars")
the system is developed using technical decisions aimed at cost minimization
ERP-1 is designed and developed as equipment with the state-of-art element base, available for a wide range of home consumers
