The accuracy of the inclination sensor means what
With the tilt sensor technology continues to breakthroughs, precision tilt sensor also becoming smaller and smaller as we buy when the tilt sensor without asking precision tilt sensor in the end what it means? We are not going to buy relatively small precision tilt sensor tilt sensor at the time of purchase it?
Accuracy refers to the actual tilt angle of the sensor is an angle sensor measuring multiple (≥16 times) the measured mean square error. We are not saying that we have relatively little purchasing precision tilt sensor tilt sensor at the time of purchase, but to judge the accuracy that we need according to their actual situation is much, then go to make a purchase.
Accuracy of measurement of the tilt sensor is closely related to the following indicators:
1, sensitivity error - depending on characteristics of the core itself sensitive devices, but is associated with the frequency response, also referred to as amplitude-frequency characteristic. After the actual test, the impact on the sensitivity of small, negligible. 2, zero offset - dependent on the core itself characteristic sensitive devices, sensor means in the case where no angular input (e.g. absolute level), the sensor measuring the output is not zero, the actual output value is the zero offset angle. Whether this indicator sensor can be set to zero with nothing to do
3, non-linear - it can be corrected by follow-up, depending on how many calibration points. The more calibration points, the better the nonlinear
Tilt sensor life is generally relatively short, and it is a relationship of environment, so we pay attention to the harsh environment to protect the sensor when using the tilt sensor, is particularly important that we must always be above mechanical car the detection sensor and replace the lost, the high-temperature operation, and so is not conducive to long life tilt sensor
