Abstract: A measurement method of angle sensor′s dynamic angle error is presented aiming at the measure of angle sensor′s dynamic accuracy which needs to be solved extremely. Working Principal, process and the expression of measuring results in dynamic measurement are produced. The uncertainty of measurement result is also assessed. We find the electromagnetic effect from table induces reading unsteadiness, which makes a bigger uncertainty. The fixing error also makes the uncertainty bigger. A study direction is found to prefect the dynamic angle measurement method.

Key words: Angle sensor, Dynamic angle, Uncertainty
