World’s lowest noise vibration sensors set new reference for low to medium frequency MEMS sensing

World’s lowest noise vibration sensors set new reference for low to medium frequency MEMS sensing VS1000 series sensors from Colibrys set a new reference in DC- to medium-frequency vibration sensing, offering the best combined bias-stability, repetitive high-shock resistance, linearity and noise performance (7µg/√Hz in band with the 2G range) on the market.

An embedded self-test feature also ensures that the device remains functional at all times, and a hermetically-sealed ceramic package ensures robustness and durability.

Wide, flat frequency response

Offering a large and flat frequency response from DC to Hz to 1500Hz (±5%, min), the series is built around an optimised MEMS (micro-electromechanical system) sensor, an improved die attach, a new ASIC (application-specific integrated circuit) with a powerful 200,000 Hz internal clock and a temperature sensor.

High bias and scale factor temperature stabilities

The new ASIC-optimised architecture provides bias and scale factor temperature stabilities of ±0.2 mg/°C (min/max) and 120 ppm/°C (typical). It also features overload and aftershock recovery detection. The non-linearity becomes almost nonexistent with 0.1% of the full scale output (typical) under vibrations.

Ranges and performances

The sensors are available with a wide range of dynamics from ±2 to ±200g, making them suitable for a wide range of applications such as active suspension systems in railway locomotives, structural health testing and MEMS inertial navigation systems.
