One Sensor - Three Axis - Three Signals



Development History:



Inventor Ploechinger





First Prototype 1993







Silicon Chip:
First Version Single Axis 1994







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.




  • Three signals for: tilt and acceleration in x-axis and y-axis, acceleration in z-axis
  • No moving mechanical parts
  • High shock resistance
  • No hysteresis
  • Best sensitivity around zero
  • Static inclination signal
  • Small power consumption
  • Small package outline.



Prelimnary Technical Datas:
