3-axis tilt sensor DTS

XYZRS-485RS-232

Product Overview
DTS is a high-performance digital MEMS dynamic tilt sensor developed by RUICOM Technology for attitude monitoring of moving platforms. It outputs real-time three-dimensional attitude data (roll, pitch, yaw) under vibration and motion by fusing a three-axis accelerometer and gyroscope with an adaptive Kalman filter. Multiple digital interfaces (RS485, RS232, TTL) facilitate system integration in industrial applications.

Measurement Principle and Robustness
Based on a non-contact measurement principle, DTS computes attitude without a reference mounting surface. The built-in high-precision ADC and gyroscope compensation correct nonlinear errors, orthogonal coupling, temperature drift and centrifugal effects, reducing motion-induced measurement deviations. DTS operates in dynamic and static modes, offers strong EMI immunity, and resists high mechanical shock and vibration for deployment in harsh environments such as industrial automation, construction machinery and rail transport.
