详细说明:
挪威SENSONOR公司微机械MEMS陀螺STIM202,已知精度最高的MEMS陀螺,性能优于光纤陀螺VG949P。 Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates via a "plug & play" high-level RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters. For more advanced users, STIM202 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
- 5 different sampling rates available
- 5 different bandwidths available
- LP filter -3dB frequency can be set individually for each axis
- RS422 protocol, bit rate and line termination
- Selectable output unit: angular rate [deg/s] or incremental angle [deg]
