FIELD: measuring equipment.
SUBSTANCE: invention relates to thermometry and can be used for determining temperature of surface of part made of copper or its alloys, in range of 250…300 °C with maximum error of ±2.5 °C. Pyrotechnic mixture contains components-oxidants, components-reducing agents, as well as component-binder and an elastic polymer shell. Oxidising agents used are potassium nitrate and potassium permanganate. Reducing components are zinc and sulphur. Binder component is adhesive BF-6. Ratio of components (wt%):
40÷50 vol% of rated content of BF-6 in ready composition is used to form elastic polymer shell.
EFFECT: technical result is reduced tendency to premature ignition and, as a result, high accuracy of detecting temperature.
