ИСТИНА

The influence of changes in ambient temperature on the characteristics of seismic instruments has long been known. With the advent of electronic versions of such equipment, the problem of temperature influence has not disappeared anywhere, since any useful electrical signals always coexist with electrical noise. There is an opinion that the main reason for the appearance of increased electrical noise of seismic devices (when the temperature of the surrounding space changes) is the instability of the parameters of the electronic components that make up their construction. At present, in general, the noise caused by temperature gradients cannot be taken into account exactly. A simple thermostating of the entire device as a whole helps in most cases to protect only from external temperature drops. But it turns out to be completely useless in the presence of internal local sources of heating. This paper presents an experimental study of the change in the characteristics of geo-hydroacoustic buoys when the temperature changes, both in the surrounding space and inside them.
