Low Outgassing Accelerometers
Low Outgassing Accelerometer Types & Their Applications
Mini-triaxial Accelerometers
Spacecraft structures are often made of thin, light-weight materials and require low mass accelerometers. Full-scale spacecraft random vibration responses are three-dimensional, so the combination of a triaxial, low-mass ICP® (IEPE) accelerometer with low outgassing properties is recommended. PCB® Model 356M208 meets this requirement with a low mass of one gram and low outgassing characteristics.
Shock Accelerometers
Separation of booster stages cause shock events that may be transmitted to the spacecraft payload. Low outgassing ICP® (IEPE) accelerometers may be launched with the payload or used in a vacuum chamber to simulate launch conditions.
High Temperature Accelerometers
Environmental stress screening is often performed in thermal vacuum chambers to verify operating characteristics. PCB® Model 357A07, (p. 10) offers a hermetic, low-mass package with a wide operating temperature range from -100 to +500 °F (-73 to +260 °C).
