Accelerometers meet demanding applications

The products are based on Murata’s proprietary 3D MEMS technology and they offer a number of product features and benefits for the most demanding applications, including Electronic Stability Control (ESC), Hill Start Assistance (HSA), Electronic Parking Brake (EPB), 2-axis acceleration measurements, and 360° vertical orientation measurement.

The sensing element and the measuring ASIC are environmentally protected with silicone gel resulting in excellent performance and reliability 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’s 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.
