AdvancedOrientationSystems,Inc(AOSI)是美国著名的倾角传感器制造品牌，成立于1995年，很快成为角度测量行业的一个组成部分，并自豪地制造的优质产品。主要包括：AOSI倾斜传感器、AOSI交配连接器、AOSI测斜仪等，AOSI倾斜传感器是近年发展起来的一种先进的聚合物制造，这种高度一致的传感器迅速成为合乎逻辑的，可靠的和低成本的更换，以脆性旧风格的玻璃元件，广泛应用于医疗、军事、汽车和其他高可靠性行业中。

Advanced Orientation Systems, Inc. (AOSI) was founded in January of 1995 with a goal of developing and producing the next generation of tilt sensors. AOSI quickly became an integral part of the angle measurement industry, and proudly manufactures products in the USA.AOSI’s base line of Dual Axis tilt sensors are manufactured from a recently developed advanced Polymer. Inert to most chemicals and mechanically stable, this new material made it possible to manufacture dual axis miniature tilt sensors in the tens of thousands without any significant unit to unit structural deviation.
