Somni Acceleration sensors

 

Acceleration sensors
Vibration detection is one of the most applied (health) monitoring methods. Get direct insight in system behaviour and monitor deviations over time by measuring acceleration with Somni acceleration sensors. Our accelerometers are available in many shapes and sizes,ach one with its own specifications.

Dynamic response
The sensor produces a flat response over its specified region and increases in sensitivity towards its resonance. Both sensitivity and phase show minor deviations up to at least 1/3 of the resonant frequency. This makes the sensor particularly suited for use in applications in which timing is important.

Calibration
Each acceleration sensor is calibrated prior to shipment. Our standard calibration procedure generates a measurement report which includes information on sensitivity, flatness and resonance. A calibration formula is provided to transform the optical signal into acceleration data.

Design of our sensor
The acceleration sensor mechanisms made by Somni are based on a decade of experience in transducer design. Our vibration sensors comprise of a proof-mass which is part of a compliant mechanism. Due to this robust monobody design the sensor response is robust and reliable. All transducers are frictionless and produce accurate signals regardless of g-level.
