Abstract

1,215,923. Measuring temperature electrically JOSEPH LUCAS (INDUSTRIES) Ltd. Feb. 13, 1968 [Nov. 24, 1966], No. 52642/66. Heading G1N. The temperature of a fluid, e.g. that of the gases flowing through the jet pipe of a gas turbine engine, is measured using apparatus in which the flow of gas from a nozzle 17 interferes with the flow of gas between nozzles 10, 14, the nozzle 10 being connected to an inlet 12 from the jet pipe and the nozzle 14 being connected via a device 18 with the nozzle 17. The device 18 is such that it produces a time dependent on the temperature of the gases in the gas flow between the nozzles 14, 17 so that the flow of gas between the nozzles 10, 14 is interrupted at a frequency dependent on the temperature of the gases. The pulses produced in the flow into nozzle 14 are transmitted via passage 15, diaphragm 21 to an electrical pressure sensitive transducer 23 from which a signal is derived which is indicative of changes in frequency of the pulses and therefore of the temperature of the gases. This signal may be used to control the fuel supply to the engine. The nozzles 10, 14, 17 are located in a chamber 13 connected to the inlet pipe 12, passages 11, 27 being connected across a restriction 28 in the pipe 12 across which a constant pressure difference, independent of temperature changes in the gas, is maintained by the provision of a further venturi restriction 29 through which the gases pass at sonic speeds.
