FIELD: measuring equipment.
SUBSTANCE: invention relates to thermometry and can be used to measure fast-flowing high-temperature processes in gas dynamics and to construct automatic gas temperature control systems for gas turbine engines. Differential system for measuring the gas temperature of a gas turbine engine is proposed, comprising information processing unit 3 and two measuring channels 1 and 2, each of which has jet generator 4, piezoelectric transducer 5, electronically-tunable filter 6 with sensor-type switch 12, phase comparator 7, key 8, single-vibrator 10, voltage-code converter 13, sawtooth voltage generator 9 whose output is connected to the control input of electronically-tunable filter 6 and voltage-code converter 13 via inverter 11.
EFFECT: increase in the accuracy and reliability of the device.
