Title:
DEVICE AND METHOD FOR TESTING SENSOR OF STEERING WHEEL
Document Type and Number:
Japanese Patent JPH0412238
Kind Code:
A
Abstract:
PURPOSE:To detect the output state of a pressure sensor by applying simultaneously uniform pressurizing force to plural pressure sensors and leading out an output of the sensor in this case in a state that a sealed state of a pressure container is maintained by an electric signal leading-out means. CONSTITUTION:A pressure container 30 which can contain a steering wheel main body 1 is prepared, and a prescribed internal pressure state is made by a pressure adjusting means which can adjust internal pressure of the container 30 and consists of an air pressure source 38, a duct line 34, a supply valve 35 and an exhaust valve 36, and uniform pressurizing force can be applied simultaneously to plural semiconductor sensors. Also, an output of the sensor in this case is led out to the outside in a state that the sealed container 30 is maintained, by an electric signal leading-out means consisting of a junction line 42 and a connector 41 for leading out the output of the sensor to the outside of the container 30. Accordingly, in a state that the main body 1 is contained in the container 30 and prescribed pressurizing force is maintained, an electric signal corresponding to the pressurizing force in that case can be outputted.
