Measuring unit ADIS of inertia

Favorites Email to a friend Date: 22/8/2011

ADIS16355 is a digital output, all warm calibrated high performance, little inertial measurement system which U.S.A. ADI Company put out newly. The output is SPI serial interface, offer three angle speed signals, three linear accelerometer signals, temperature sensor signal, mains voltage signal and an auxiliary analog input. Factory troposphere lean towards and degree of sensitivity go on all warm accurate to normalize.

First. Characteristic:

1.Volume only 23mm *23mm *23mm!

2.Factory to degree of sensitivity, zero lean towards and installation error go on all warm to normalize ' From -40 ¡æ +85 ¡æ)

3.The angle speed measurement limits of three axles: 75 degrees of ¡À / s, 150 degrees of ¡À / s, 300 degrees of ¡À / s (can be presumed through the procedure)

Definition: 14

4.The measurement limits of acceleration of three axles: ¡À 10g

Definition: 14

5.Bandwidth: 350Hz (can presume other arbitrary bandwidth values through the procedure)

6.Embedded temperature sensor

7.SPI serial interface export

8.12 auxiliary ADCs input and 12 DACs export

9.Zero of digital control is simply normalized

10.Numerically controlled sampling rate

11.Digital control is filtered

12.The figure encourages the self-checking function

13.Programmable to call the police

14.Programmable power management

15.Auxiliary digital I/O interface

16.Service voltage: 5V¡À 5%

17.Bear and assault the acceleration: 2000g (under energization situation)

Two. Typical application:

Navigation and controlling of the vehicle

The platform is stabilized and controlled

Motion control and analysis
