ARRANGEMENT FOR REMOTE MEASURING OF TEMPERATURE Russian patent published in 2008 - IPC G01K7/24 

FIELD: the proposed invention refers to arrangements for measuring of temperature of remote objects and may be used at conducting geothermal researches coming into obligatory complex of geophysical controlling methods for exploitation of oil and gas fields and underground depositaries of gas.

SUBSTANCE: the arrangement for remote measuring of temperature has thermal sensitive elements included in the opposite arms of the bridge measuring scheme, an amplifier of the signals about deregulation of the bridge measuring scheme, a stabilized source of feeding, an impulse converter of the signals of the thermal sensitive signals, an armored cable of communication, a ground information processing block including blocks of feeding, separation, processing and registering of the impulse signal and also a current limiter consisting of two identical resistors included in the feeding diagonal of the bridge scheme in-series and symmetrically relatively to central points, at that one of the resistors is switched to the positive and the other- to the negative output of the stabilized source of feeding.

EFFECT: increases accuracy of measuring of temperature and reliability of registration of distribution of thermal field along the axis of the well.
