The invention relates to a monitoring arrangement (12) for monitoring the clamping quality of a workpiece carrier clamped in a clamping device (3, 40, 49) as well as a clamping system with clamping device (3, 40, 49) and such a monitoring arrangement (12). The monitoring arrangement comprises at least two sensors (A1-A4) for the independent detection of the clamping quality of a clamped workpiece carrier or workpiece. The monitoring arrangement also comprises a transmitting device (14) and a receiving device (21), wherein the transmitting device (14) is constituted such that it transmits the determined or calculated parameter or parameters redundantly to the receiving device (21).
