Accelerometer application division

Accelerometers are divided according to their applications: marine, aerospace, vehicle, etc. If it is used on a ship, especially if it is used underwater, the requirements for attitude are very high and the inertial navigation equipment is required to run for a long time, so it is necessary to choose products with higher precision. The quartz flexible accelerometer is with high bias stability and scale factor stability, which is consistent with this type of selection. If used in aerospace, most of these navigation systems have short continuous operation times and low accuracy requirements. They use quartz accelerometer with a larger range. Quartz flexible accelerometer has the characteristics of simple structure and high accuracy.

It is widely used in inertial navigation systems and geodetic systems.

The accelerometer is a force-balanced sensor that converts the input acceleration into a small displacement of its flexible pendulum and balances it with feedback force. Due to the use of a force feedback loop, this quartz flexible accelerometer has the characteristics of high accuracy and strong anti-interference ability. It’s suitable for low-frequency and low-g value acceleration measurement, it is one of the indispensable key components in inertial navigation and guidance systems. Quartz accelerometers are generally used in navigation and guidance systems such as launch vehicles, spacecrafts, missiles, aircraft, and ships. Low-precision accelerometers are generally used in oil exploration, mechanical sensing, etc.
