Accelerometers

VTI's accelerometers are based on our proven and robust silicon capacitive 3D MEMS technology.

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. 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. VTI´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. The sensing element in use is over-damped.
