摘要： A position measurement system is provided to determine a time difference between a first event and a second event. Position values are hereby determined from an individual periodic signal or from a plurality of periodic signals, wherein a first position value is determined using a measurement signal evaluation means when a first event occurs, and a second position value is determined using the measurement signal evaluation means when the second event occurs. The time difference is determined from the first and second position values. As a result, the time difference can be measured between two events with a high temporal resolution, with a reduction of electromagnetic interference caused by the time measurement.

摘要： Two sensors scan a measuring scale, which can be displaced in relation to the sensors and comprises a plurality of equidistant measuring gradation, and deliver corresponding measuring signals. The measuring signals are periodic during a uniform relative displacement of the measuring scale, essentially sinusoidal and essentially phase-shifted by 90° in relation to one another. They have an essentially identical amplitude and a base frequency that corresponds to the relative displacement of the measuring scale. During a delivery period of measuring signals, the measuring scale carries out a relative displacement through one measuring gradation. Corrected signals are determined from the measuring signals using correction values. A signal of the position of the measuring scale in relation to the sensors is determined in turn using said correction signals. Fourier coefficients are determined in relation to the base frequency for the corrected signals or for at least one supplementary signal that is derived from the corrected signals, said coefficients being used in turn to update the correction values. Said correction values contain two shift correction values at least one amplitude correction value and at least one phase correction value for the measuring signals, or part of said values, in addition to at least one correction value for at least one higher frequency wave of the measuring signals.

摘要： A measuring arrangement includes a measuring unit for detecting an operating variable of a machine, and a control unit connected to the measuring unit by a bi-directional digital data connection to control the machine. The measuring unit has a sensor for detecting an analog measuring signal for the operating variable, an evaluation unit for digitalizing and evaluating the analog measuring signal, and a monitoring unit for checking the threshold value of the analog measuring signal. The data connection transmits digital measuring or monitoring information determined by the evaluation unit and the monitoring unit, from the measuring unit to the control unit, and transmits a digital control command for initiating a self-test of the monitoring unit, from the control unit to the measuring unit. A modification system provides targeted amplifying or damping of the analog measuring signal supplied as a test signal during the self-test of the monitoring unit.
