FIELD: mining engineering.
SUBSTANCE: device contains two bench marks, at first it is installed angular movement transducer, connected to block, and controller connected to angular movement transducer by conductor line. Block is enveloped by cable sheath, connected to the second bench mark by one end by means of elastic coupling, and by other - by means of adjustment mechanism.
EFFECT: reliability improvement of its work ensured by design simplification and expansion of application area.
