The design, development, and testing of two hightemperature transducers are described. One measures vibration amplitude and frequency, and the other measures acceleration. Both were designed to detect aerodynamic panel flutter during boost and re-entry of the X-20 Dynasoar, then under development. These transducers are electrical resistance strain gage types. Part details discussed are the pendulum, damper, sealing, and case configuration. Both transducers are also discussed in greater detail with respect to natural frequency, damping, strain gage application, and output.
