An accelerometer is an instrument used to measure the acceleration of an object. It has a wide range of applications in many fields, including aerospace, automotive engineering, and sports medicine.
1. Sensitivity: for an instrument, the higher the sensitivity, the better, because the higher the sensitivity, the easier the acceleration changes in the surrounding environment, the greater the acceleration changes, the natural output voltage changes correspondingly larger, so that the measurement is easier, more convenient, and the measured data is more accurate. Ericco's quartz accelerometer ER-QA-03A has a scaling factor of 15-50ppm, bias repeatability is 10-50μg and Class II non-linearity repeatability is 10-30μg/g2.
2. Bandwidth: Bandwidth refers to the effective frequency band that the sensor can measure. For example, sensors with hundreds of Hertz bandwidths can measure vibrations; A sensor with a bandwidth of 50 Hz can effectively measure inclination.
3. Range: The range required to measure the movement of different objects is not the same. It should be measured according to the actual situation. The measuring range of the accelerometer is usually in the unit of gravitational acceleration (g), and the common range is +2g, +4g, +8g, etc. This means that an accelerometer can measure the acceleration of an object in any direction, whether it is negative (deceleration) or positive (acceleration).As a wide range accelerometer ER-QA-03B's capable of measuring up to ±70g
4. Measurement accuracy: It is also an important technical specification. Measurement accuracy is usually expressed in terms of displacement error or percentage error. For example, an accelerometer with an accuracy of +0.1g means that its measurement is within +0.1g of the true value. The higher the accuracy, the more accurate the measurement results.
5. Response time: Also a key metric. Response time refers to the time it takes for the accelerometer to receive a change in acceleration to produce a stable result. In general, the shorter the response time, the better, because it means the accelerometer can detect the acceleration change more quickly.
The technical specifications of the accelerometer include measurement range, measurement accuracy, response time, resolution, sampling rate, operating temperature range and interface type. These technical specifications determine the performance and reliability of the accelerometer in different application scenarios. When selecting and using accelerometers, we need to weigh these technical specifications according to the specific needs to obtain the best measurement results and performance.
