The invention relates to more accurate rotative and linear positional measurement for a rotary-linear drive. A measuring system comprising a linear sensor (12) and a rotary sensor (20) is disclosed. A decoupling unit (11,14,17) decouples the rotary displacement from the linear displacement of a shaft (10). The decoupling unit (11,14,17) has either a first measuring section (11), which is coupled in a fixed manner to the shaft to be measured (10) and tapped by the linear sensor (12) and a second measuring section (17), which is exclusively non-rotatably coupled to the shaft to be measured (10) and is tapped by the rotary sensor (20), or a first measuring section, which is coupled in a fixed manner exclusively linearly to the shaft to be measured and is tapped by the linear sensor and a second measuring section, which is non-rotatably coupled to the shaft to be measured and is tapped by the rotary sensor. In each case, the linear displacement is decoupled from the rotary displacement for the measuring process, permitting high-resolution standard measuring sensors to be used.
