FIELD: warning and monitoring devices for transport, industry, public utilities to warn about dangerous situations and to indicate ambient temperature. SUBSTANCE: ice warning device depends for its operation on electronic temperature gage principle but, as distinct from known devices, it is designed so that error in temperature measurements as four digital points does not exceed ± 0.4 C and at two extreme points of measurement range, + 2 C. EFFECT: improved stability of temperature thresholds, economic efficiency, simplified design, easy maintenance. 6 cl, 3 dwg |
