Where Is The Quartz Accelerometer Used?

Small Size and High Temperature Quartz Accelerometer

Quartz accelerometer is an important physical measuring instrument, can measure the linear or rotational acceleration of objects, with simple structure, high precision, high sensitivity, good long-term stability, small size, low power consumption, etc. It is the acceleration, speed, distance, swing, vibration, tilt and other physical quantities sensitive, measurement, control replacement products. Widely used in aerospace, machinery, construction, earthquake, transportation, geological exploration and scientific research and other fields.

Quartz accelerometers are used for:

Inertial navigation and guidance system

Navigation guidance systems for missiles, aircraft, ships, and chariots must have speed and position information. In the case of low requirements, people use airspeed meters, Mach number sensors, odometers, etc., but with the performance requirements of the weapon system. Improve, the above instruments can not meet the requirements. The line accelerometer can be installed in a moving object to directly measure its acceleration, and then obtain the speed and position. The measurement accuracy is high and the dynamic performance is good, which is much better than the airspeed meter and the odometer. Therefore, linear accelerometers are one of the most important applications for inertial navigation guidance systems.ER-QA-01A is a high-precision airborne quartz accelerometer with bias repeatability ≤10μg, repeatability ≤10 PPM, second-order nonlinear repeatability ≤10μg/g2, and its performance characteristics can meet the needs of high-precision equipment. In the field of aerospace, quartz flexible accelerometers can be used for aircraft navigation, attitude control and flight safety.

Tilt measurement and leveling system

In the gravitational field, a line accelerometer can measure changes in gravitational acceleration. When the sensitive axis is perpendicular to the horizontal plane, the accelerometer indicates the unit of gravity acceleration; if the sensitive axis is tilted, the output is the product of the gravitational acceleration and the sinusoidal function of the tilt angle. Using this principle, it can be used as tilt measurement and leveling. For example, the fire control gun sight radar, air defense radar leveling; in addition, by measuring the lateral acceleration of the train, the car to control the tilt angle, so that it can still run at high speed on the curve.In the mechanical field, it can be used for vibration analysis and mechanical fault diagnosis; In earthquake research, it can be used for map construction and earthquake prediction.

Overload switch

The overload switch is used for the bullet spreading system of the mother missile. In this system, the motion acceleration of the female projectile at the expected height is calculated and set by the ballistics. The axial acceleration of the overloaded switch mounted on the bomb, when the preset acceleration is reached, the overload switch outputs a bullet to dissipate the control signal, ignites the projectile, and causes the bullet to be thrown from the female projectile. A number of bullets are like a net woven into a bomb, so that the target being hit has nowhere to hide. It is a powerful weapon against enemy positions and large equipment.

Development trend

The future development trend of quartz flexible accelerometer industry is mainly manifested in the following aspects:

1. High precision and sensitivity. With the continuous progress of science and technology, people's requirements for quartz flexible accelerometers are also coming.The higher the accuracy and sensitivity of the product will become a development trend.

2. Miniaturization and integration. The application of quartz flexible accelerometers in aerospace, automotive and mechanical fields is gradually increasing large, miniaturization and integration will become the future development trend.

3. Digital and intelligent. Digitalization and intelligence will penetrate into all areas of the quartz flexible accelerometer to promote the line .The rapid development of industry.
