Capacitive Vibration Sensors
NEUCHÂTEL, Switzerland, May 20, 2008 -- Colibrys SA said its new wide-bandwidth capacitive accelerometers set new performance standards for vibration sensing and are expected to displace piezoresistive sensors in health and usage monitoring systems (HUMS), aeronautics, railway technologies and auto crash-test applications.
The Colibrys VS9000 accelerometer is a MEMS (microelectromechanical) -capacitive sensor based on a bulk micromachined silicon element, a low-power ASIC for signal conditioning, a microcontroller for storage of compensation values and a temperature sensor, the company said.

The new extended bandwidth of its capacitive sensors, combined with a high degree of miniaturization, make the product line ideally suited to meet the increasing requirements of vibration measurement systems (such as high reliability, long-term stability, signal-to-noise ratio, size and power) that can no longer be met by current piezoresistive sensor technology, according to Colibrys.
“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.”
The new line covers the full range from ±2 g to ±2000 g and offers a constant frequency response (< 5 percent variation) up to 2 kHz, Colibrys said. The VS9000 will be on display June 9-11 at Sensors Expo (Booth 1113) in Rosemont, Ill.
