MM7.10  | BODAS Inertial sensor Product description Product description The inertial sensor is available as MM7.10 and MM7.10AC. Description MM7.10 and MM7.1AC The purpose of the inertial sensor is to measure the physical effects of the yaw rate, rate of roll, and of transverse, longitudinal and vertical acceleration. When mounted appropriately (i.e. according to the offer drawing), the sensor measures the yaw and roll rates as well as the lateral, longitudinal and vertical acceleration of the vehicle. In order to prevent signal interference or negative power supply impacts on the sensor,...
