Multi-axis inertial sensing system
Keyword: Sensors
BEI Systron Donner Inertial Division introduces the MotionPak 110, a low cost, multi-axis, solid state, NEMS based, inertial sensor system that is stated to be accurate, rugged and highly reliable. Incorporating three orthogonally mounted GyroChipt quartz (MEMS) rate gyroscopes and three silicon accelerometers, it provides outputs of angular velocity (rate) and linear acceleration about three axes (Plate 4). These outputs are in both analogue and digital format.
Possible applications include flight-testing equipment.
Plate 4 New multi-axis inertial sensing system for control and instrumentation applications
MotionPak II is described as reliable, compact and rugged and can be operated from either dual bipolar (±15v DC) or single ended (+11 to +16v DC)supplies, providing high or low resolution outputs with dual voltage power input or low resolution only when single ended voltage only is available.
The digital RS 232 output is available with either power input, the PC based Data Acquisition software being Windows 95/98 and NT 4.0 compatible. A CD-ROM supplied with each unit incorporates data logging software.
Stated to be suitable for operation at temperatures from -40°C to +85°C,MotionPak 11 has an internally mounted temperature sensor, should thermal compensation be desirable in the application. All connections are made via a standard 25 way "D" type socket.
The unit weighs 1.26Kg, has a small footprint 128mm wide by 113mm high, and is 117mm deep. Four fixing ears on the base provide easy mounting. The versatile, fully self-contained system, incorporates internal power regulation and signal conditioning electronics and is designed for fast start up and long operational life. An optional carrying case provides additional protection in transit.
Incorporating BEI GyroChip technology, MotionPak 11 is said to combine the latest advancements in micro-machined (MEMS) quartz-rate sensors.
