METHOD OF PROVIDING TEMPERATURE STABILITY OF PARAMETERS OF A MOLECULAR-ELECTRONIC CONVERTER IN HIGH FREQUENCY RANGE Russian patent published in 2020 - IPC G01P15/08 G01V1/16 G01V1/18 G01D3/28 G12B7/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, in particular to a method of providing temperature stability of parameters of molecular-electronic converters used in linear and angular accelerometers. This invention can be used in seismic sensors, sensors for stabilization of moving objects and systems of inertial navigation, accelerometers and hydrophones of high stability and accuracy. In the invention, the problem is solved due to 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. For this purpose, in working fluid of converter at distance from 2 to 50 mm from anodes there installed are additional electrodes, which are at potential by 100–500 mV above potential of cathodes, and current is passed through anodes, the value of which depends on temperature according to certain law. Effect of current passing through anodes consists in temperature-controlled change of anode concentration, which increases with increase of current and decreases in reverse case.

EFFECT: providing accuracy of measurement of angular and linear movements and acoustic signals by molecular-electronic transducers in wide temperature range.
