One Sensor - Three Axis - Three Signals
First Prototype 1993
Silicon Chip: Dual-axis
Current Chip: "Inclinos"
Available soon: Inclinos chip mounted in ceramic housing
Principle of operation:
Based on Patents DE 4243978, EP 1111395, US 6,722,199: "A sensor for detecting a rotational movement, an angular acceleration, a tilt or an acceleration"
Integrated micro-machined heating elements in a gas chamber produce low density zones and convection currents along the field of force. Highly sensitive, temperature dependent, resistive micro-machined elements detect temperature fluctuations of the surrounding gas flow. New operation and readout methods (Pat. pend.) enable the sensor to measure inclination/tilt of 360 degrees with full accuracy for two axes, lateral acceleration for x- and y-axis and vertical acceleration for z-axis.
Prelimnary Technical Datas:
Measuring range from µg to 60g (see "Output-Signals") Resolution of inclination: 0.1 degree, resolution of acceleration: 200 µg, frequency 0 to >100 Hz (maximum amplitude), power consumption approx. 40 mW..
