IonizersThe AGS11151 a: Single-Axis Capacitive MEMS Acceleration and Tilt Sensor
15 May 2007
The new GS1 single-axis acceleration sensor from Panasonic Electric Works utilises Micro Electro Mechanical Systems (MEMS) capacitive technology.
This G-sensor comprises two integral elements. A MEMS sensor and a customised Application Specific Integrated Circuit, (ASIC) combine to convert acceleration via a capacitive signal into an electrical output.
The operating principle of the MEMS sensor depends on two finger-like electrodes, one moving and one static. When a capacitance change between the movable and stationary electrodes occurs, the output signal is linearly proportional to the acceleration that was applied to the sensor. The GS1 operates within a range of ±2G and the resulting directly proportional output voltage is 2.5±1V. Principal distinguishing features of the GS1 are high sensitivity (1V/G) and high accuracy (+/- 5% FS). Operating temperature range: -40 to +85oC. Developed for automotive applications and for machinery/equipment where tilting needs to be detected, typical applications are car navigation systems and skid control.
The GS1 is housed in a 6.2x8.5x1.6mm Surface Mounting Device (SMD) ceramic case.
