Vostok-T transmitters

Transmitters for search and control of cleaning pigs

“VOSTOK-T” transmitters are designed for generating electromagnetic signals, which give an opportunity to identify the location of cleaning pigs using the low-frequency mole (receiver) “VOSTOK-NL”. Transmitters’ method of procedure is based on transmission of electromagnetic waves of infra-low frequency 13, 22 Hz and an encoded signal with “SEMIGOR” frequency, delivered as signals in “signal-pause” format or in continuous-wave mode.

Transmitters allow tracking and identifying the location of a pig in case of its stoppagein the pipeline. They are installed onto the cleaning pigs, which are further launched into pipelines.

Transmitters are able to be used together with low-frequency moles “VOSTOKNL”,low-frequency mole manufactured by “TRANSNEFT-DIASKAN”, any modifications of low-frequency moles manufactured by “APRODIT”, receiver manufactured by “SEMIGORYE”, low-frequency mole manufactured by “ROSEN Group” and other low frequency moles, operating with signals of frequency 22 Hz.
