THERMIC MODEL OF INSPECTED OBJECT Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: invention is related to aids measuring temperature of inspected fire and dangerously explosive object subjected to emergency loads without direct contact with it. It can be specifically used to check temperature of ammunition transported in containers. Thermic model of inspected object has modeled body composed of heat insulator and core and temperature-sensitive element located in core. Model is provided with metal envelope of spherical shape that houses modeling body whose core is manufactured in the form of ball. Gaseous heat insulator is arranged in clearance between ball and envelope. Members of attachment of core are made in the form of two interacting groups ensuring point contact between core and outer envelope and constancy of clearance under action of operational overloads and of impact emergency loads. Members of attachment provide for invariability of contact area of members thanks to limitation of level of specific pressure in point of contact. EFFECT: expanded application field, improved authenticity of model. 1 cl, 3 dwg
