SYSTEM WITH MULTIPLE TEMPERATURE SENSORS Russian patent published in 2014 - IPC G01K1/02 G01F1/84 

FIELD: measurement equipment.

SUBSTANCE: system (120) with multiple temperature sensors comprises a network (180) of temperature sensors, including temperature-sensitive resistors R_T1 and R_T2 (186, 187) and frequency-selective filters (184, 185), connected to multiple temperature-sensitive resistors R_T1 and R_T2 (186, 187). Frequency-selective filters (184, 185) pass separate signals that vary with time into the network (180) of temperature sensors, and separate weakened signals that vary with time are passed from the network. The system (120) additionally includes a temperature variation controller (161) connected to the network (180) of temperature sensors and configured for introduction of separate signals that vary with time into the network (180) of temperature sensors, to receive weakened separate signals that vary with time in response to introduction of signals. Weakened separate signals that vary with time are weakened by temperature-sensitive resistors (186, 187) for generation of two or more substantially simultaneous values of temperature from weakened separate signals that vary with time.

EFFECT: increased accuracy of produced measurement data.
