FIELD: monitoring and measuring equipment.
SUBSTANCE: invention relates to means of controlling a downhole sample in the oil and gas industry during extraction and delivery thereof to a laboratory. Device consists of medium-separation piston, primary sensors, meter and device of contactless data exchange, which includes inductance coil and transceiver. In addition, an inductance meter and a switch connected between the transceiver and the inductance coil are installed, and the inductance coil is switched between the inductance meter and the transceiver.
EFFECT: technical result is binding of thermobaric parameters of the downhole sample by the end of sampling and assurance of integrity of the downhole sample in order to exclude the fact of substitution.
