Colibrys Extended Bandwidth Capacitive Vibration Sensors to Displace Piezoresistive Technology for HUMS Applications



Sensors Expo Rosemont, IL, USA, 9-11 June 2008 - The new Colibrys wide bandwidth capacitive accelerometers set new performance standards on vibration sensing and are expected to displace piezoresistive sensors in Health and Usage Monitoring Systems (HUMS), Aeronautics, Railway technologies and Automotive crash testing applications. The recognized high performance level of capacitive sensors, well proven for inertial and seismic applications, is now also available for vibration sensing.


The ever increasing requirements on vibration sensors in terms of reliability, long term stability, signal to noise, robustness, size and power can not be met anymore by the current piezoresistive sensor technology. The new extended bandwidth of the Colibrys capacitive sensors, combined with a high degree of miniaturization, make this new product family ideally suited to meet the increasing requirements of vibration measurement systems.


“It is part of our strategy to provide new advanced sensors for a wide range of vibration applications” said Philippe Krebs, Business Development Manager at Colibrys for vibration sensing. “This new VS9000 product has already been successfully qualified for safety critical railway technologies applications to improve security and comfort of passengers and demonstrators have already been integrated on bridges for preventive monitoring of the structure.”


This new product family, covering the full range from ±2 g to ±2000 g and offering a constant frequency response (< 5% variation) up to 2 kHz, consolidates the position of Colibrys as leading edge independent European supplier of capacitive accelerometers for vibration, inertial and seismic sensing applications.
