BWK226S Low Cost Dual-Axis Digital Output Inclinometer Technical Manual

BWK 226S Low Cost Dual-Axis Digital Output Inclinometer Introduction Designed by Bewis Sensing Technology LLC, BWK226S is a low cost dual-axis digital output inclinometer, adopting the latest industrial level MEMS accelerometer. Its measuring range is ±90°, highest accuracy is 0.2°, working temperature is -40℃~+85℃, the product with a small size and low weight, can meet space-restricted application requirements. This product converts static gravity field changes into angle changes, It outputs horizontal angle values temperature drift, simple to use, and strong resistance to external disturbances....

Specifications© Electrical Specifications Parameters Resolution: The measured minimum change value that the sensor can detect and resolve within the measurement range. Accuracy: The error between the actual angle and the Root mean square(RMS) of the measured angle of the sensor (>16 times). Bewis SensinglTechnologyiLLCl
