An accelerometer is a device that measures proper acceleration ("g-force"). Proper acceleration is not the same as coordinate acceleration. An accelerometer at rest on the surface of the Earth will measure an acceleration g= 9.81 m/s2 straight upwards. By contrast, accelerometers in free fall orbiting and accelerating due to the gravity of Earth will measure zero.
Murata is the global market leader in low-g acceleration sensors for automotive applications. The extensive accelerometer product range includes high performance digital and analog accelerometers for both safety critical automotive and industrial applications. Murata accelerometers are based on the company's proprietary 3D MEMS technology and they offer a number of excellent product features and benefits for the most demanding applications. The sensing element and the measuring ASIC are assembled in a dual-in-line or dual-in-flat-line plastic package with pins for surface mount and re-flow soldering. They are environmentally protected with silicone gel resulting in excellent performance and reliability in a humid environment and at temperature cycling. In addition, the robust sensing element design with over damped frequency response enables excellent performance even in harsh and vibrating environments. The measuring direction is parallel or perpendicular to the mounting plane. The ASIC includes an on-chip EEPROM memory with the calibration coefficients for unit interchangeability. Murata accelerometers include enhanced failure detection: digitally activated self-test, calibration memory parity or check sum check and continuous connection failure detection. The products are intended for horizontal or vertical measurements.The zero point temperature dependence is less than 1mg/°C.
