CXLTG-Series
Powerful Sensing Solutions for a Better Life
HIGH PERFORMANCE ACCELEROMETER
The TG-Series 3-Axis accelerometers are high performance ±2g and ±10g sensors, featuring
precision three-layer silicon differential capacitive MEMS sensing elements that provide ultra low noise and excellent stability. The TG-Series sensors are fully signal conditioned and factory calibrated.
The single-ended high level analog outputs do not require external signal conditioning and are easy to interface to standard data acquisition systems.
Platform Leveling
Automotive Testing
The TG-Series operates on a single DC supply from 3.3 V to 5.5 V and includes a high performance integrated temperature sensor for additional accuracy under extreme temperature applications. The typical current consumption of 1.5mA makes this triaxial device attractive for battery operated systems.The sensor is packaged in an industrial anodized aluminum package that is moisture resistant and rugged for industrial and automotive applications.
