CAPILLARY THERMOMETER Russian patent published in 1995 - IPC

FIELD: thermometry. SUBSTANCE: thermometer has temperature probe implanted, which has thermal bulb 1, flexible basic capillary 2 which communicates with thermal bulb 1, and flexible compensation capillary 3; capillaries are filled with dielectric fluid. Registration unit 4 is connected with capillaries 1 and 2; moreover, both capillaries are disposed mutually in form of a doubled spiral. Thermometer is insensitive to power high-frequency and microwave electromagnet fields. Metrological characteristics of the thermometer such as high speed of operation, precision, and long-time stability are improved significantly. EFFECT: improved operational characteristics. 5 cl, 4 dwg
