How It Works The sensor utilizes advanced capacitive MEMS technology. Inside the device, a micro-mechanical pendulum responds to the Earth's gravitational field. When the sensor tilts, the gravitational component acting on the pendulum changes, causing a variation in capacitance. The internal circuitry amplifies and filters this signal before converting it into a precise inclination angle output. Because the measurement is non-contact, the sensor provides stable real-time angle data with excellent reliability and minimal wear over time. This operating principle makes the sensor ideal for applications requiring continuous position and attitude monitoring. Conclusion The LCA318T/LCA328T MEMS Tilt Sensor combines compact design, high accuracy, and robust industrial performance. It is widely used in Construction Equipment, platform leveling, antenna positioning, and vehicle chassis measurement. Additionally, it can support advanced applications such as Structural Health Monitoring, Bridge Monitoring, and Solar Tracking System installations where accurate inclination data is essential for operational safety and performance. As industrial automation continues to evolve, reliable inclinometer technology remains a critical component of modern monitoring solutions.

They operate on the Coriolis principle, using electrostatic drive and capacitive sensing, and can be modeled as a mass-spring-damper system. However, their performance is degraded by errors such as frequency split, stiffness coupling, and especially temperature-induced demodulation phase error, which worsens zero-rate output (ZRO). A team from Beihang University, Zhejiang University, and Nanjing University of Science and Technology proposed a high-precision phase error identification method that requires no extra instruments. By applying electrostatic forces to quadrature correction electrodes, the demodulation phase error can be identified over the full temperature range. Experiments confirmed its consistency and accuracy. The method, based on quadrature-voltage-induced equivalent angular rate (QIR), was compared with the Coriolis-induced equivalent rate (CIR) approach using four quad-mass gyroscopes (QMGs). Tests across temperatures showed QIR compensation yielded smaller ZRO and better repeatability. Keys: Phase compensation RMSE reduced by 54–86% ZRO repeatability improved by 35–95% Bias instability by 50–75% Angle random walk by 62–69% Future work aims at self-calibrating, real-time phase error identification.
