| Abstract [eng] |
T–U characteristics of the analog temperature sensors of types LM35 and LM35A are investigated. It is obtained that a basic error of measurement of temperature introduces the spread of output voltage at 00C. It is evaluated an error in the determination of temperature from the output voltage of sensor in the cases of approximation by the polynomials of the first and second power. Smaller error is obtained during the application of a polynomial of the second power. It is obtained that with the precise calibration of sensors of the type LM35 the smaller error the determination of temperature can be obtained with the approximation by the polynomial of the second power. It is not established for the sensors of the type LM35A of essential difference. |
