THIN-FILM RESISTANCE THERMOMETER Russian patent published in 1999 - IPC

FIELD: instrumentation engineering. SUBSTANCE: thin-film resistance thermometer has two resistors connected in parallel. One of them is temperature dependent and based on nickel, the other one is temperature independent. Ratio of resistances of temperature dependent resistor to temperature independent one lies within limits of 0.22-0.4 at O C. Temperature coefficient of resistance of temperature dependent resistor is equal to (5.8-6.4)10^-3 C at 100 C. Such realization of thermometer makes it possible to design thin-film temperature converter of resistance with universal static characteristic. EFFECT: design of thin-film temperature converter of resistance with universal static characteristic. 2 dwg
