Active compensating method of sensitivity temperature drift of convection-based Tilt sensor

摘要

When environment temperature is changed, the properties of convection-based tilt sensors are changed, which is so-called sensitivity temperature drift. Methods of sensitivity compensation are introduced according to mechanism of this kind of tilt sensor: temperature distribution induced by the heat source plays a key role in sensing tilt angle. The sensitivity temperature drift was researched, a new method of sensitivity temperature active compensating was proposed, and sensitivity temperature active compensating was accomplished.
