Product Description
The 16488C multi-degree-of-freedom inertial measurement unit is a
complete inertial system with a built-in three-axis gyroscope, a
three-axis accelerometer, a three-axis magnetometer and a pressure
sensor for measuring the three-axis angle of the carrier parameters
such as rate, acceleration, three-axis magnetic field, air
pressure, etc., output data after error compensation (including
temperature compensation, installation misalignment angle
compensation, nonlinear compensation, etc.) according to the
communication protocol through SPI. - Three-axis digital gyroscope:
- ± 450º/s dynamic measuring range;
- Zero-bias stability: 5.1 °/h
- Triaxial digital accelerometer:
- ± 18 g dynamic measuring range;
- Zero-bias stability: 0.07mg (ALLAN);
- High reliability: MTBF > 20000h;
- Guaranteed accuracy within the full temperature range (-40 ºC ~ 70
ºC): built-in high-performance temperature calibration and
compensation algorithm;
- Suitable for working under strong vibration conditions;
- Interface 1 channel UART, 1 channel SPI, 1 channel CAN
