DEVICE MEASURING AND CONTROLLING TEMPERATURE Russian patent published in 1997 - IPC

FIELD: instrumentation engineering, medical and laboratory equipment. SUBSTANCE: device incorporates glass vessel filled with mercury, sealed glass capillary joined to vessel, thermometric scale and glass body. Elastic mercury-proof, irregular in thermal stability and heat conductance layer of composite material is located on outer surface of body. In zone of scale material has transparency within limits 0.8- 0.98. Layer includes polymer to create elasticity and mercury-proofness. Glass particles are added into layer to increase thermal resistance in zone of vessel and metal particles are added to enhance heat conductance. EFFECT: enhanced operational reliability and stability of device. 4 cl, 2 dwg
