ZHANG Congpeng, SONG Laijun. High precision 2D inclinometer with temperature compensation[J]. 2019, (6): 86-88. DOI: 10.13873/J.1000-9787(2019)06-0086-03.
A high precision two-dimensional inclinometer with temperature compensation is introduced. The central control unit based on STM32
the dual axis angle signal acquisition circuit
the data communication circuit and the temperature acquisition circuit are designed. An algorithm for improving sensor precision and temperature compensation is developed. The experimental results show that the full-scale error of inclinometer after compensation reaches 0. 14 %
and the resolution of the sensor is 0. 003°
which can meet the requirement of industrial attitude measurement.
