2-Axis MEMS Rate Gyroscope
Introduction
The ER-2MG-202 is a two axis MEMS gyroscope, the pitch and heading of the carrier can be measured in real-time, and the angular rate can also be output in real-time. It has the advantages of small size, low power consumption, light weight and good reliability. The products can also meet the application requirements of the corresponding fields. That is, it can replace traditional rate gyros, including DTG and semi-liquid floating gyros.
Application
Measure the angular rate of pitch and roll of the carrier and output it in real-time
Features
Short startup time
Digital or analog output (optional)
Small size, low power consumption, light weight, simple interface, easy to install and use
Output the measured value of two axial angular rate of carrier independently, continuously
Measure the angular rate of pitch and heading of the carriers and output it in real-time
