一九八四年十一月在英国举办了国际传感器博览会,在这次博览会上美国森德斯特兰德数据控制公司(Sundstrand Data Control, Inc.)展出2180、2181、QA-900、QA-1300、QA-1400等伺服加速度计。这些加速度计是石英挠性加速度计,可用于飞行控制、大g测量、加速度和振动测量、小量程加速度测量及惯性导航。森德斯特兰德伺服加速度计其性能指标、环境条件、电气/物理性能以及价格详见下页表。
In November 1984, the International Sensor Expo was held in the UK, where Sundstrand Data Control, Inc. exhibited 2180, 2181, QA-900, QA -1300, QA-1400 and other servo accelerometer. These accelerometers are quartz flexible accelerometers that can be used for flight control, large g measurements, acceleration and vibration measurements, small range acceleration measurements, and inertial navigation. Senderland servo accelerometer performance indicators, environmental conditions, electrical / physical properties and prices see the table on the following page.
