Keywords: Industrial Applications, Accelerometers, Safety Critical

VTI 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.

VTI 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. 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.

Sensor Elements (Dies) | VTI

In some cases, ready-made sensors do not meet the exact requirements of the specific application; the sensor size might not be suitable, the power consumption too high or the measurement range not optimal. These needs can be satisfied with VTI's sensor elements, since capacitive sensing elements utilized in VTI component manufacturing can be purchased also as an element only.
