| | | As safety components, ignition switches, control pedals and locking systems leave no room for production errors. Torque sensors can determine the operating torque of elements such as ignition switches during the active production process. Control monitors use the rotation to analyze the operation torque, compare the results with the specified tolerance and remove flawed products. Every single step of the production of safety components is monitored by sensors. Suppliers to the automotive industry can guarantee the error-free operation of their components by carrying out tests during the active manufacturing process. This approach reliably eliminates the risk of after-sales product malfunction. Torque sensors can test the working order of installed ignition switches during the active manufacturing process. The torque measured during rotation of the spring-preloaded components must comply with the specified tolerances. Torque sensors can test typical torque ranges, e.g. a range from 1 N-m to 3 N-m within short production cycles. In order to achieve this, the sensors are lifted pneumatically. A servo motor then rotates them by the required angle, e.g. by 120°, to test the torque against a spring-preloaded ignition switch. | | |
