Quartz flex accelerometer solution – How to choose quartz servo accelerometers?
1.If quartz pendulous accelerometer is used on ships, especially for underwater applications. It requires high attitude and requires inertial navigation equipment to run for a long time. Therefore, it is necessary to use products with higher precision. SenNav’s SNQ1 & SNQ2 quartz flexible accelerometer bias stability And scale factor stability is very high, in line with such selection.
2.For aerospace applications, most of these navigation systems have a short continuous operating time and require low accuracy, but require a relatively large range. The SenNav SNQ3 quartz flexure accelerometer related models are available.
3.The application areas are medium-range aircrafts and large-scale surface ships, mid-range ground-to-ground missiles, cruise missiles, etc. Middle precision accelerometers (generally, instruments with an accuracy in the range of 1×10-5g to 1×10-6g) can be selected. The quartz-flex accelerometer is a representative product in the mid-accuracy accelerometer. Such applications require accelerometers with medium precision and high reliability. Available SNQ1 and SNQ5 quartz flexible accelerometer related models.
4.For oil drilling instruments, emphasis is placed on strong impact, strong shocks and high temperatures stability. SNQ4 and SNQ6 vibrating quartz accelerometer have different temperatures 125/150/180, users can choose according to actual requirements.
