Excerpt from "Life Cycling" Test on Several Strain Gage Pressure Transducers Sinusoidal pressure calibrators are now becoming available for the dynamic calibration of pressure transducers at frequencies up to several thousand hertz. All of these devices are designed to produce dynamic calibrations of the transducer under test with reference to a built - in Standard transducer which is subjected to-the same pressure variations. It is ap parent that in the course Of determining one frequency response character istic, both transducers may be subjected to several hundred thousand pres sure cycles. Additional dynamic calibrations will impose many more pres sure cycles on the reference transducer. If the performance of the ref erence transducer deteriorates with pressure cycling, the validity of the dynamic calibrations may be in doubt.
