Sentek Instrument - Model NovaPT-E - Engine Pressure Sensors - Datasheet

Dynamic pressure measurement at ultra-high temperatures is highly desirable in many industrial processes. Limited maximum service temperatures of semiconductor transducers or piezoelectric devices force engineers to use either water cooling to the sensors or to employ standoff tubes to guide pressure to a point where these transducers can be used.  Besides increased complexity and cost, the bulky size of the cooled sensors makes access to many locations difficult.  In the meantime, the pressure guiding tubes damp the dynamic signals, which are the true signals for combustion diagnostics and gas turbine compressor stall/surge detection.
