Product Description

BWM826 Digital Dual Axis Inclinometer RS485/TTL Optional High-Accuracy 0.005° 




BWM826 can convert the change of static gravity field into the change of inclination, and directly outputs the value of horizontal inclination through digital mode. The cost-effective dual axis inclination sensor with MEMS technology and digital output is adopted. The measurement range is ± 30 °, the maximum accuracy can reach 0.005 °, and the working temperature is - 40 ℃ - + 85 ℃. The product adopts high-precision MEMS accelerometer and high-resolution differential fractional analog converter, with built-in automatic compensation and filtering algorithm, which largely eliminates the error caused by environmental changes.
