СКВАЖИННОЕ УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ И КОНТРОЛЯ ДАВЛЕНИЯ НА ПРИЕМЕ ПОГРУЖНОГО НАСОСА

摘要

FIELD: survey of boreholes or wells, particularly measuring temperature or pressure in running wells. ^ SUBSTANCE: device comprises land-based assembly and submersed assembly including pressure transducer made as pressure unit linked to measuring resistor with output connected to land-based assembly inlet through diode and communication line. Land-based assembly includes power source, computing unit, digital indicator, the first analog-digital power source voltage converter, and the second analog-digital power source voltage converter. Land-based assembly input is linked to input of the first analog-digital converter having output linked to the first input of the computing unit. Land-based assembly input is also connected with the first output of power source having the second output linked with ground through resistor and with input of the second analog-digital converter. Output of the second analog-digital converter is connected to the second input of computing unit. The first output of computing unit is connected to digital indicator. The second output thereof is linked to power source input. ^ EFFECT: increased operational reliability. ^ 1 dwg
