in a variety of configurations including radially outward of outer surface 15 or recessed within housing 12 probe 11 which is inserted into a combustion system captures the fluid medium pressure and temperature which is then transmitted measured and recorded by other components of the instrumentation assembly referring back to fig1 and to fig3 a first tubular conduit 23 is fixed to probe 11 at first end 13 such that it is in fluid communication with first passage 17 first tubular conduit 23 extends from probe 11 through an isolation valve and to transducer mounting block 24 which contains a dynamic pressure transducer 25 for measuring the dynamic pressure of the fluid medium within first passage 17 and first tubular conduit 23 a first cable 26 is fixed to transducer mounting block 24 and extends from transducer mounting block 24 to a means for recording the dynamic pressure of the fluid medium within first conduit 23 typically an electronic monitoring system programmed to record data at predetermined intervals a second tubular conduit 27 is fixed to transducer mounting block 24 and extends to a means for measuring the internal static pressure 28 of the fluid medium contained within second tubular conduit 27 which was transmitted by first tubular conduit 23 the fluid medium within second tubular conduit 27 as with first tubular conduit 23 is captured by probe 11 from within a combustion chamber fixed to and extending from means for measuring internal static pressure 28 is a second cable 29 that extends to a means for recording the internal static pressure within second tubular conduit 27 referring now to fig1 and 4 a third tubular conduit 30 is fixed to probe 11 at first.
