METHOD FOR ENSURING TEMPERATURE AND TIME STABILITY OF PARAMETERS OF MOLECULAR ELECTRONIC GEOPHYSICAL SENSORS FOR OIL AND GAS EXPLORATION SYSTEMS
Abstract
The paper presents a new technical solution for the device of the primary sensing element of the MET sensor that stabilizes the temperature characteristics of the device due to the fact that the background current flowing through the cathodes of the converting element is controlled by a specially designed electronic circuit depending on the ambient temperature. In this case, a current is passed through the anodes, the value of which depends on the temperature according to a certain law. The cathode current value is maintained when the temperature changes by changing the carrier concentration at the anode and the corresponding concentration gradient. Thus, the proposed mechanism stops the change in the diffusion coefficient with temperature due to the corresponding reverse change in the concentration gradient of the electrolyte carriers. The paper presents the theoretical basis of the proposed model and the experimental verification of the stabilization effect for the prototypes. Limit currents, voltage characteristics and a family of amplitude-frequency characteristics depending on the ambient temperature were measured. The stabilization effect is compared with the traditional scheme of sensitive elements.
