Gas line profiles as well as the acceleration sensor works

At present, the linear acceleration sensor has dozens, most of them are solid substances as "quality testing" that is mass. The solid mass in a large impact (or high overload) condition will produce a strong inertial force root, which cause the sensor to lose the ability to work. Therefore, they are a big impact (or high overload) the application is limited occasions. In order to overcome the existing deficiencies of the linear acceleration Crankshaft Sensor, developed a new linear acceleration sensors. The sensor is a gas instead of a solid mass, thereby avoiding a large mass inertia force generated. This new line of other sensors, acceleration Crankshaft Sensors can not match with the characteristics of simple structure, low cost and high reliability, especially after impact by a high 1600ug still work. Heat rises, air conditioning decline, which is often seen in our daily life phenomena. For example, the still air burning candle, the flame temperature gas solid as the center of the presence of increased buoyancy, cold air constantly replenished from below, thus forming elongated flame, which is a natural air convection. Gas line acceleration Crank Shaft Sensor is the use of this phenomenon, the theory is based fluid mechanics "natural convection" theory. Natural convection Forced convection is a relative terms. Forced convection by fans, pumps, etc., causing fluid flow; natural convection speed in the absence of force, the fluid flow convection still it is a gravitational field acting on the fluid in the density gradient flow generated. Natural convection speed is generally much smaller than the speed of forced convection. Thus, the natural convection effect is often overlooked. However, under certain conditions, natural convection will play a decisive role. Gas formation conditions of natural convection is present gravitational field and the gas has a density gradient. In fact, in addition to gravity off, overload can also cause than the force of acceleration or when the natural flow. Gas line acceleration sensor is the use of acceleration overload caused by natural convection test line acceleration.
