Understand how linear strain gage accelerometers measure motion in telemetry, with practical design insights.
This overview explains the two main types of strain gage accelerometers used in telemetry—unbonded and bonded—and how they convert mass movement into an electrical signal. It emphasizes design principles, damping, frequency response, and factors that influence accuracy and reliability in flight and ground systems.
- Learn the basic operating principle of spring-mass accelerometers and how strain gages capture relative motion.
- See how damping, natural frequency, and the figure of merit affect measurement fidelity.
- Understand key design considerations for reliability, such as materials, gage type, and excitation requirements.
- Get guidance on interpreting common specifications like range, sensitivity, and bridge resistance.
Ideal for readers involved in flight telemetry, sensor design, and instrumentation alignment.
