POSITION MEASURING DEVICE AND METHOD FOR OPERATING SAME

The invention relates to a position measuring device. The device comprises a scale carrier (30) with measuring scales (40), a scanning device (50) for generating a position signal (PS) by scanning themeasurement scale (40); a processing unit (60) for processing the position signal (PS) into a digital position value (POS); an interface unit (70) for communicating with a subsequent electronic device (80), wherein the position measuring device (5) is associated with at least one crash sensor (100), the crash sensor generates an analog or digital measurement value (MA, M) from which a temporal profile of the crash event can be determined, the measurement value (MA, M) being transmitted to an evaluation unit (110, 210, 310) in which the crash event can be determined by means of a control unit(150) by evaluating the temporal profile of the measurement value (MA, M). The invention also relates to a method for operating such a position measuring device. 本发明涉及一种位置测量装置，其包括：具有测量刻度(40)的刻度载体(30)，用于通过扫描测量刻度(40)生成位置信号(PS)的扫
