一般注記There have been investigated and published many applications of fluidic amplifier device to large variety of engineering fields because of its trouble-proof, heat-and vibration-resisting characteristics derived from the fact that it has no moving parts. Fluidic turbine inlet gas temperature sensor should be cited as one of the most important and right applications. Although some papers on it are already published, they are all confined to show the final test results or performances of the sensor. Prototype fluidic turbine inlet gas temperature sensors we have designed and manufactured for experimental use on the consideration of basic mechanism of oscillation have two outstanding features in its geometry; first, they have the output port whose corss area is smaller than that of main nozzle. second, they have the feedback path whose cross area suddenly increases and remains constant up to control port. These features made it possible, at least principally, to get the fluidic turbine inlet gas temperature sensor with high resolution and low noise,large amplitude output signal. In this report, we described the basic design consideration and philosophy of fluidic turbine inlet gas temperature sensor as well as some test results and performances of them. In appendix, we analyzed and calculated the phase shift of pressure wave caused by sudden increase of wave guide cross area.
