Description


SST54220 inclinometer is a new-generation inclination sensor that combines the data of the gyroscope and the accelerometer.  It can not only accurately measure the static inclination angle, but also measure the inclination angle under the action of short-term external acceleration. It is a new type of inclination measurement product which is especially suitable for various mobile mechanical equipment applications.

 

Conventional inclination sensors based on MEMS, electrolyte, potentiometer and other principles can only adapt to the measurement of the inclination angle without the horizontal acceleration of the device. After the horizontal acceleration of 2g (X and Y directions) lasts for 2s, the measurement error may reach 30° or larger. In the field of mobile construction machinery and equipment, it is difficult to obtain ideal working conditions without the interference of acceleration in the X and Y directions.

 

The SST54220 inclination sensor can still accurately measure when the external horizontal acceleration (X and Y directions) reaches 2g and lasts for 5~10s, and the additional error generated does not exceed ±0.05°.


Application

 

Various types of jib cranes, such as container reach stackers, crawler cranes, tire cranes, truck cranes, etc.
