Abstract

CONSTRUCTION OF THE GEOPHYSICAL MEASURING INSTRUMENTS IN THE GEOPHYSICAL RESEARCH UNDERTAKING IN 1952-61 Summary The paper deals with construction of the own measuring apparatuses used in the geophysical prospections. Recently, a production of following apparatuses was begun, viz.: - dynamic small-dimension geophones for seismic works, - low frequency geophones for refraction works, - apparatuses for induction measurements of 20 kHz frequency, - resistivimeters and electronic autocompensators, - geoelectric instruments for deep symmetrical electroresistance logging, - shot-apparatuses and sending-receiving instruments, - anti-shocking immersion galvanometers, - telluric apparatuses and others. The instruments mentioned above are of faultless construction and work excellently.
